Проверка запирания компьютера управления двигателем
By using a key shield
A metallic shield inserted between the analogue module antenna and the electronic device located in the key prevents the former from reading the latter. a faulty key can be simulated in this way. this shield can be made by drilling a 8 mm hole in the centre of a suspension sphere thread protection cap (1)
Выполняемая процедура
- Выключить зажигание
- Open the driver's door and wait for 10 seconds (the key-in-ignition audible warning stops)
- Insert the ignition key into the 8mm hole drilled in the shield
- Switch on the ignition using the screened ignition key: the transponder warning lamp in the instrument panel flashes, and the audible warning emits a pulsed sound
- If the ECU is correctly locked, the engine cannot be started
By removing the ignition on information
Выполняемая процедура
- Выключить зажигание
- Open the driver's door and wait for 10 seconds (the key-in-ignition audible warning stops)
- Remove fuse F2
- Включить зажигание: the transponder warning lamp in the instrument panel does not come on
- Attempt to start the engine: the transponder warning lamp in the instrument panel flashes and the audible warning emits a pulsed sound
- If the ECU is correctly locked, the engine cannot be started
Using the transponder warning lamp in the instrument panel
Выполняемая процедура
- Выключить зажигание
- Open the driver's door and wait for 10 seconds (the key-in-ignition audible warning stops)
- Закрыть дверь водителя
- Включить зажигание
- Observe the time required to unlock the engine ECU (the time that the transponder warning lamp in the instrument panel is on for)
- Выключить зажигание
- Включить зажигание
- Observe the time that the transponder warning lamp in the instrument panel is on for (engine ECU unlocked)
The second time the ignition is switched on: as the CPH does not need to unlock the ECU, the warning lamp should come on for a shorter period of time
ПримечаниеThe time that the warning lamp is on for also depends on the type of engine ECU fitted to the vehicle. certain ECUs respond faster than others
Using the LED for vehicles fitted with an alarm
For vehicles fitted with an alarm, and depending on the CPH configuration (программирование): the alarm LED can also be used to check the state of the engine ECU
Зажигание включено
- The LED stays off then starts to flash 10 seconds after the driver's door is opened
- The LED will flash slowly (1 Hz) to indicate that the CPH has been informed that the engine ECU is locked
Зажигание включено: the LED will continue to flash until the CPH is informed that the engine ECU has been unlocked
ВниманиеПри выключении зажигания: the LED flashes immediately if the CPH has not been informed that the engine ECU is unlocked
The diagnostic equipment cannot communicate with the CPH
