- Wiring diagram

Test requirements







- Corresponding fuses on E-box in engine compartment, left side, for Clutch Position Sensor -G476- must be OK.
- Motronic Engine Control Module (ECM) Power Supply Relay -J271- (relay position R4) must be OK, check.
- Battery voltage must be at least 11.5 Volts.
- All electrical consumers such as, lights and rear window defroster must be switched off.
- Ground (GND) connections between engine and chassis must be OK.
- Ignition switched off.


Test sequence
Observe safety precautions.
Observe rules for cleanliness.

- Remove engine cover, removing and disassembling air filter/engine cover.
- Remove battery and battery holder.







- Disconnect 5-pin connector -4- from Clutch Position Sensor -G476-
- Re-install battery holder and battery.
- Connect battery.

Checking voltage supply







- Connect multimeter using adapter cables to terminal 5 of connector and chassis Ground (GND) for voltage measurement.
- Switch ignition on.

Specified value: at least 11.5V

- Switch ignition off.

If there is a malfunction in voltage supply:
- Check wire between 5-pin connector terminal 5 and corresponding fuse holder for open circuit according to wiring diagram.

Wire resistance: max. 3.0 Ohms

- Erase DTC memory of Engine Control Module (ECM). Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes

If there is no malfunction in voltage supply:
- Check wires to Engine Control Module (ECM) according to wiring diagram.

Checking wires to Engine Control Module (ECM)
- Connect test box to 94-pin connector of wiring harness. Test Box, Connecting For Wiring Test

Engine Control Module (ECM) is not connected.







- Check wires between test box and 5-pin connector to Engine Control Module (ECM) for open circuit according to wiring diagram.

Terminal 1 + socket 1
Terminal 2 + socket 41

Wire resistance: max. 3.0 Ohms

- Check wires for short circuit to each other.

Specified value: Infinity Ohms

- Erase DTC memory of Engine Control Module (ECM). Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes

If no malfunctions are found in wires:







- Unclip Clutch Position Sensor -G476- at sensor cylinder -arrow- and replace.
- Erase DTC memory of Engine Control Module (ECM). Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes
