Functions/components controlled
Sensors and functions which are different to previous types are marked in bold text .
| Number | Component | Signal type/explanation |
|---|---|---|
| 2/22 | Air conditioning (A/C) relay | Connecting and disconnecting A/C compressor |
| 2/23 | Fuel pump (FP) relay | Signal for fuel pump (FP) on/off switch. In a collision where the SRS is deployed it also sends a signal to the Engine Control Module (ECM) to turn off supply to the fuel pump (FP). |
| 2/32 | System relay | Controlled by the Engine Control Module (ECM) provides sensors and functions with voltage supply. |
| 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 (ETM) refer to CAN communication. |
| 4/71 | Electronic Fan Control Module | For the signals transmitted between the engine control module (ECM) and the electronic fan control module refer to CAN communication. |
| 5/1 | Central Electronic Module (CEM) | For the signals transmitted between the engine control module (ECM) and the central electronic throttle module refer to CAN communication. |
| 7/15 | Front heated oxygen sensor (HO2S) 1 | Power supply for heating PTC element |
| 7/82 | Rear heated oxygen sensor (HO2S) 2 | Power supply for heating PTC element |
| 7/103 | Rear heated oxygen sensor (HO2S) 3 | Power supply for heating PTC element |
| 7/104 | Front heated oxygen sensor (HO2S) 4 | Power supply for heating PTC element |
| 8/6 - 8/11 |
Injectors | Controlled individually (sequentially). |
| 8/18 | Canister purge (CP) valve | Continuously controlled, it controls the flow from the EVAP canister to the engine intake side. |
| 8/19 | Continuously Variable Valve Timing control valve (CVVT) | Continuously controlled, it controls camshaft setting. On turbocharged engines it controls the exhaust camshaft and on normally aspirated it controls the intake camshaft. |
| 8/28 | Turbocharger (TC) control valve | Controls turbocharger (TC) boost pressure, see the information on turbocharger (TC) control system. |
| 8/44 | Fresh air valve, Canister purge (CP) | The valve is either off or on and opens or closes the canister fresh air intake during a leak diagnostic. |
| 20/3 - 20/8 |
Ignition coil/power stage for cylinders 1 - 6 | 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. |
