Input signals
Emergency mode (Limp-home)
Remarks:
If signal is missing from the atmospheric pressure sensor, the value 90 kPa (130 psi) is used when calculating. This is comparable to an elevation of approx. 1000 meters (0.62 miles). This will lower the boost pressure slightly but will hardly be noticeable.
If a signal is missing from the mass airflow sensor (MAF), the air mass is calculated using the throttle's position and the RPM signal.
If signal is missing from the throttle position sensor (TPS), MAF will take over.
| Input signal from | Used for/Remarks | |
| 1 | Engine control module (ECM) | - |
| 2 | Knock sensor (KS) | A knock sensor - located between 2nd and 3rd cylinder - is used to detect knocking. |
| 3 | AC linear pressure sensor | Pressure in the AC system. Input for Engine control module (ECM) for A/C and fan strategy. |
| 4 | ECC control panel / AC controls | Request to turn AC on and off. |
| 5 | DSA control module | Request to reduce power in case of wheel spin. |
| 6 | Control module immobilizer | Communication only within the first two seconds between Engine control module (ECM) and immobilizer control module. Then immobilizer control module's internal relays switches to connecting to diagnostics socket (k-line) for diagnostics communication with Engine control module (ECM). |
| 7 | AW50-42 Transmission control module (TCM) | Communication with Transmission Control Module (TCM) takes place via two cables. Signals are composed in the same way as in CAN communication protocol. Up to 38 different signals are communicated via this system. |
| 8 | ABS control module | Car's speed from right front wheel sensor. |
| 9 | Front heated oxygen sensor (HO2S) | Oxygen content in exhausts before the catalytic converter. This sensor is located directly after the turbocharger in front of CCC. |
| 10 | Rear heated oxygen sensor (HO2S) | Oxygen content in the exhausts is sensed after the catalytic converter. It is located after the catalytic converter. It is used for diagnostics and fuel adjustment purposes. |
| 11 | Throttle position sensor (TP) | Senses how much the throttle is open. No idle switch is installed. |
| 12 | Engine coolant temperature sensor (ECT) | This sensor is also used for the instrument. The value is converted in Engine control module (ECM) and is sent to the instrument as a digital signal. |
| 13 | Air temperature sensor (IAT) | Measures the air temperature between the charge-air cooler and inlet manifold. |
| 14 | Camshaft sensor (CMP) | Cylinders' work cycles. Located on the exhaust camshaft. Also gives consideration to variable valve times. |
| 15 | mass air flow (MAF) sensor | Measures the air mass that passes through the air filter. It is based on the warm film principle. |
| 16 | atmospheric pressure sensor | Measures the air pressure. Engine control module (ECM) translates this value to the elevation at which the car is driven. It is used to protect the turbocharger from overspeeding in thin air. As well, the fuel mixture is reduced when the car is started at high altitude. |
| 17 | Pressure sensor | Measures the absolute pressure in the inlet manifold. Same sensor as the altitude sensor, but located in the inlet manifold. Located between cyl. 3 and 4. |
| 18 | Impulse sensor (RPM) | Engine RPM and crankshaft position. |
