Alarm Sherhan Logicar 5i with autostart function allows you to remotely start the car engine, maintaining a comfortable temperature in the cabin in winter or cool in summer. However, many owners encounter difficulties when setting up this option for the first time - the system requires the correct sequence of actions, taking into account the features of a specific car model and compliance with safety measures. In this article you will find step-by-step instructions with menu illustrations, analysis of common errors and tips for optimizing autorun.

Difference Logicar 5i from previous versions - an improved algorithm for protecting against false positives and the ability to flexibly configure timers. But even experienced car owners sometimes miss important nuances: for example, the need to activate neutral in a manual transmission or check the battery charge level before the first start. We will analyze all these points, and also tell you how to avoid draining the battery during frequent autostarts and what to do if the system ignores commands from the key fob.

Preparing the car for setting up autostart

Before activating the function, you must make sure that the car is technically ready for remote start. First and most important — check the serviceability of all systems:

  • 🔋 Battery: the voltage must be no lower 12.4 V (measured with the ignition off). If the battery is weak, autostart may be interrupted or may not work.
  • 🚗 Gearbox: for manual transmission the lever must be in neutral position, for automatic transmission - in mode P (Parking).
  • 🔑 Immobilizer: if a regular immo is installed in the car, a lineman will be required (for example, BP-03 or Fortin).
  • 📶 Keychain connection: distance to the car when setting up - no more 5-7 meters.

Pay special attention handbrake: On some car models (eg Kia Rio or Hyundai Solaris) autostart is blocked if the parking brake is activated. Also check if there are any errors on the instrument panel - for example, Check Engine may prevent the engine from starting.

💡

If your vehicle is equipped with Start-Stop, disable it before setting up autorun. Otherwise, the alarm may not correctly recognize the engine status.

Step-by-step instructions: how to enable autostart on Sherhan Logicar 5i

The algorithm for activating the function depends on the type of gearbox. Below are instructions for mechanical and automatic transmissions. Important: all actions are performed with the ignition off!

For cars with manual transmission

  1. Place the gear shift lever in neutral position.
  2. Turn on the ignition (without starting the engine) and wait until the indicator on the key fob lights up Immo (if any).
  3. Turn off the ignition and remove the key from the castle.
  4. Click the button III (closed lock) on the key fob to arm the car.
  5. Hold the button I (open lock) + III simultaneously during 3 secondsuntil the siren sounds twice.
  6. Autorun is activated. To check, click the button II (engine icon) — the engine should start.

For cars with automatic transmission

  1. Make sure the selector is in position P (Parking).
  2. Turn the ignition on, wait for the immobilizer tag (if any) to be read, then turn off the ignition.
  3. Click the button III on the key fob for arming.
  4. Hold down the buttons I + II on 5 secondsuntil a confirmation tone sounds.
  5. For a test run, use the button II.

If the engine does not start after completing these steps, check:

  • 🔌 Connection immobilizer crawler (if available).
  • 📡 Quality of communication between the key fob and the alarm unit (try to get closer to the car).
  • ⚙️ Timer settings in the alarm menu (the operating time may be set to zero).

Configuring autorun parameters in the Sherhan Logicar 5i menu

After successfully activating the function, it is recommended to configure its parameters to suit your needs. To do this:

  1. Press and hold the button I on the keychain 3 secondsuntil the signal sounds.
  2. Using buttons II (up) and III (down) select item Autostart (engine icon).
  3. Click I to enter the submenu.

The following options are available in the autorun menu:

Parameter Values Recommendations
Start timer Every 2/4/8 hours or Off Optimal for cold regions every 4 hours.
Opening hours 5/10/15/20 minutes 10 minutes enough to warm up the interior.
Temperature -5°C / -10°C / -15°C Exhibit on 2-3°C above average night temperature.
Start on alarm On/Off, time: 06:00-09:00 Useful for warming up in the morning before a trip.
Turbo timer 1-3 minutes or Off Turn it on if your car has a turbocharger.

Critical nuance: if the “Autostart” item is not displayed in the menu, this means that the function is not activated in the alarm firmware. In this case, the unit must be reflashed by an official installer.

Common mistakes and their solutions

Even with proper settings, autorun may be unstable. Here are typical problems and how to fix them:

The engine starts and immediately stalls

Reasons:

  • 🔑 The immobilizer tag is not read (check the crawler or proximity tag).
  • 🚘 The neutral sensor (for manual transmission) or the selector position sensor (for automatic transmission) is faulty.
  • ⚡ Weak battery (voltage drops below 11.8 V at startup).

Autorun does not work on timer

What to do:

  • ⏰ Check the time settings in the alarm menu (the clock may be wrong).
  • 📱 Make sure that the key fob is not discharged (the indicator should light green).
  • 🔌 Check the alarm fuse (usually 10A, located in the block under the hood).

The alarm beeps and flashes, but the engine does not start

This indicates start blocking due to:

  • 🚪 An open door or hood (check the limit switches).
  • 🔓 Unarmed car (click III on the keychain).
  • 🛑 Activated handbrake (on some models this blocks auto start).
What to do if autorun works every once in a while?

If autorun is unstable (it works, sometimes it doesn’t), the problem may lie in poor ground wire contact alarms Check the fastening of the black wire to the car body - it should be cleaned to a shine and securely tightened. Also inspect the connectors of the alarm unit for oxidation. In 30% of cases, unstable operation is associated precisely with poor grounding.

Security: how to avoid battery drain and theft

Frequent autostarts may drain the battery, especially in cold weather. To avoid this:

  • 🔋 Install AGM battery capacity for 10-15% more full-time
  • ⚡ Connect the alarm to the battery via decoupling diode (prevents stray currents).
  • ⏱️ Limit autorun time to 10 minutes.

To protect against theft:

  • 🔐 Use two-stage locking (for example, alarm + secret button).
  • 📍 Activate the function Slave mode (the key fob must be in the cabin).
  • 🚨 Install additional GPS tracker with engine blocking option.
💡

Never leave your key fob in the alarm range (for example, on a windowsill next to your car). Attackers can use repeaters to intercept the signal and steal a car.

⚠️ Attention: If you have an immobilizer bypass installed, never store it in the glove compartment or under the seat. The optimal location is inside the dashboard, away from metal parts that could shield the signal.

Additional autorun functions: timer, temperature, alarm clock

Alarm Sherhan Logicar 5i supports three types of autorun:

  1. By timer — launch at specified intervals (configurable in the menu).
  2. By temperature — activation when the interior is cooled below the set threshold.
  3. On alarm clock — one-time launch at a specified time (for example, at 7:00 before going to work).

To configure temperature trigger:

  1. Go to the autorun menu (button I → engine icon).
  2. Select an item Temperature (thermometer icon).
  3. Set a threshold value (for example, -10°C).
  4. Save the settings with the button I.

Function Alarm clock useful for those who want to warm up the car by a certain time. For example, you can program the start to 07:30to 07:45 the interior was warm. Important: the alarm goes off only once a day.

💡

If you are using temperature autostart, set the threshold 2-3°C higher than the actual night temperature. This will prevent too frequent starts and save battery power.

Compatible with different car brands

Alarm Sherhan Logicar 5i universal, but there are nuances for different brands:

Car make Settings Features Is an immo crawler required?
VAZ (Lada) Autorun works without additional modules. No (if there is no regular immo)
Toyota, Honda Lineman required Fortin or BP-03. Yes
Kia/Hyundai Need to disable Smart Key in the settings. Yes
Volkswagen, Skoda May require a CAN module for correct operation. Yes
Nissan, Renault It is often necessary to update the alarm unit's firmware for a specific model. Yes

For vehicles with Start/Stop button (for example, Mazda CX-5 or Ford Kuga) you will need an additional button press emulation module. It is connected parallel to the standard start button.

⚠️ Attention: On some models BMW and Mercedes-Benz with the system Keyless Go autostart may work unstable due to a conflict with the standard immobilizer. In this case it is recommended to use Slave keychain with tag emulation function.

FAQ: answers to frequently asked questions

Is it possible to install autostart on Sherhan Logicar 5i yourself?

Technically yes, but this will require skills in working with auto electricians. Main difficulties:

  • Correct connection to CAN bus (if it is in the car).
  • Setting up the immobilizer crawler (if equipped).
  • Programming the alarm unit for a specific car model.

If you have no experience, it is better to turn to professionals - installation errors can lead to short circuit or failure of standard electronics.

Why does auto start work at night, but the engine stalls after 10 seconds?

This is a typical situation for cars with gas equipment. The engine starts on gasoline, but does not switch to gas because:

  • There is not enough pressure in the cylinder (the reducer needs to be warmed up).
  • The gas solenoid valve does not open due to low voltage.
  • The HBO settings prohibit starting on gas.

Solution: disable autostart on gas or install gearbox preheater.

How to disable autostart on Sherhan Logicar 5i?

To temporarily disable:

  1. Hold down the buttons I + III on 5 seconds (a double beep will sound).
  2. The function will be deactivated until the next time the system is armed.

To completely disable:

  1. Go to the settings menu (button I → engine icon).
  2. Select an item Autostart: Off.
  3. Save your changes.
Is it possible to start the engine from the phone if the alarm system is connected to the GSM module?

Yes, if you have the module installed Sherhan GSM or StarLine M20. To do this:

  1. Send SMS command START to the module number.
  2. Or use the mobile application (if the module supports GPRS).

Important: before the first remote start, check the balance of the SIM card in the module and configure APN for data transfer.

What to do if the stove does not work after autostart?

This is due to the fact that the alarm does not emulate pressing the heating button. Solutions:

  • Connect an additional climate control module (for example, Comfort from StarLine).
  • Set the stove to start via CAN bus (programming required).
  • Use preheater (for example, Webasto), if the stove does not turn on remotely.
