Functions/components controlled
New sensors and functions which are different to previously known principles are marked with bold text .
| Number | Component | Signal type/function |
|---|---|---|
| 2/11 | Relay, engine cooling fan (FC) | Engine cooling fan (FC) speed, high speed or low speed. |
| 2/22 | Air conditioning (A/C) relay | Connecting and disconnecting air conditioning (A/C) compressor. |
| 2/23 | Fuel pump relay | Activation and deactivation of fuel pump. |
| 2/32 | System relay | Controlled by the engine control module (ECM) provides engine sensors and functions with voltage supply. |
| 4/30 4/6 |
ECC MCC |
Signals engine coolant temperature to climate control system which can then determine how the blower fan should be controlled after cold start. |
| 4/28 | Transmission Control Module (TCM) | For the signals transmitted between the engine control module (ECM) and the Transmission control module (TCM) refer to CAN communication . |
| 4/50 | Electronic Throttle Module (ETM) | For the signals transmitted between the engine control module (ECM) and the electronic throttle module refer to CAN communication . |
| 5/1 | Can and Driver information Module (CDM) | For the signals transmitted between the engine control module (ECM) and the CAN and Driver information Module refer to CAN communication . |
| 7/15 | Front heated oxygen sensor (HO2S) | Power supply for heating PTC element. |
| 7/82 | Rear heated oxygen sensor (HO2S) | Power supply for heating PTC element. |
| 8/6-10 | Injectors (air surrounded) | Have a special design adjusted for the assisted air controlled valve system. Controlled individually (sequentially). |
| 8/18 | Canister purge (CP) valve | Continuously controlled, it controls the flow from EVAP canister to engine intake side. |
| 8/35 | AACV valve | Stepless control from the engine control module (ECM), supplies the air surrounded injectors with air. Idle air trim is carried out using the air which passes in through the assisted air control valve. |
| 8/44 | Fresh air valve, Canister purge (CP) | The valve is either off or on and closes the canister fresh air intake during a leak diagnostic. |
| 20/3-7 | Ignition coil/power stage for cylinders 1-5 | Separate ignition coil with integrated power stages for each cylinder. Gives shorter charging interval and more power. |
| Malfunction indicator lamp (MIL) USA/CDN = Check Engine Other = engine symbol |
The lamp lights up for faults affecting the emissions. The lamp flashes for misfires which cause risk of damage to the catalytic converter. Can also light up when requested by the Transmission Control Module (TCM) and the electronic throttle module. | |
| ETS warning lamp | Can be activated by either the engine control module (ECM) or the electronic throttle module depending on where the fault was found in the system. | |
| Cruise lamp activated | Activated by the engine control module (ECM) and informs the driver that the cruise control is active. |
