FAULT-TRACING INFORMATION

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.

Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

INTERNAL FAULT

see INTERNAL FAULT

CHECKING THE COMPONENT

HINT: The diagnostic trouble code (DTC) may due to a damaged cooling fan for the control module boxes. If diagnostic trouble code (DTC) ECM-680X is stored it must be remedied first.

Activate the cooling fan for the control module box. Check the function. There must be a buzzing noise from the cooling fan when the fan for the control module box is activated.

Check that the air ducts for the control module box are not blocked.

Remedy as necessary.

INFORMATION

This diagnostic trouble code (DTC) indicates that the immobilizer code does not match between the engine control module (ECM) and the central electronic module (CEM). This may be because

  1. the immobilizer code in the engine control module (ECM) is incorrect i. e. the code does not correspond to the code stored in the central electronic module (CEM)
  2. the engine control module (ECM) is not programmed and has no immobilizer code
  3. the immobilizer code in the central electronic module (CEM) is incorrect
  4. the central electronic module (CEM) is not programmed and has no immobilizer code
  5. the engine control module (ECM) is damaged
  6. the central electronic module (CEM) is damaged.

Note. A programmed engine control module (ECM) or central electronic module (CEM) cannot be moved from one vehicle to another.

HINT: Read off the diagnostic trouble codes (DTCs) for the central electronic module (CEM).

FAULTY SIGNAL. PERMANENT FAULT

see FAULTY SIGNAL. PERMANENT FAULT

The immobilizer function is integrated in the central electronic module (CEM).

This diagnostic trouble code (DTC) can be caused by missing CAN communication. If there is a diagnostic trouble code (DTC) stored in the central electronic module (CEM) fault trace accordingly.

If no diagnostic trouble codes (DTCs) are stored in the central electronic module (CEM), try a new central electronic module (CEM).

CHECKING THE POWER SUPPLY

  1. Ignition on. Check the power supply to the stop lamp switch. Take readings between stop lamp switch terminal #1 (cable harness side) and the ground terminal. The power supply must be approximately 12 V. If there is no power supply: Check the power supply circuit for stop lamp switch terminal #1 (cable harness side). Check for an open-circuit. Check for a short-circuit to ground. Check for a blown fuse in the circuit. Remedy as necessary.

  1. Start the engine
  2. Ignition off
  3. Ignition on
  4. Read off the movement of the accelerator pedal by carefully depressing and releasing the accelerator pedal (AP). Check that the value changes with accelerator pedal movement. The value must be between approximately 0.4 V when the accelerator pedal (AP) is unaffected and approximately 4 V when the accelerator pedal (AP) is fully depressed. The fault is intermittent at the moment if the values are OK.
  1. Continue Refer to «CHECKING THE POWER SUPPLY»(ref-476771-S15795106162012060500000)

  1. Ignition on. Check the power supply (12 V) to the accelerator pedal (AP) position sensor between accelerator pedal (AP) position sensor terminals #1 (wiring side) and #3 (wiring side). Check that the power supply is approximately 12 V with the ignition on Other information: see «CHECKING WIRING AND TERMINALS»(ref-476689-S17283010372012060500000) To connect the breakout box, see «CONNECTING THE BREAKOUT BOX»(ref-476691-S38062545372012060500000) For 5 cylinder turbocharged engines -2004, see «SIGNAL DESCRIPTION»(ref-476694-S26303328522012060500000) For 5 cylinder turbocharged engines 2005-, see «SIGNAL SPECIFICATION»(ref-476694-S29505181092012060500000) .

Is the power supply OK?

  1. YES Refer to «CHECKING THE CONNECTORS AND CABLES»(ref-476771-S22785693232012060500000)
  2. NO Refer to «CHECKING COMPONENTS AND WIRING»(ref-476771-S06106535872012060500000)
  1. Ignition off. Check the signal cable between engine control module (ECM) terminal #B25 (#B35) and accelerator pedal (AP) position sensor terminal #2. Check for a short-circuit to supply voltage. Try a new accelerator pedal (AP) position sensor if no fault is found and the fault is permanent. Remedy as necessary.

HINT: After carrying out the repair, check that the fault has been remedied.

  1. Ignition off
  2. Reconnect the connectors, reinstall components etc.
  3. Start the engine
  4. Ignition off
  5. Ignition on
  6. Read off the movement of the accelerator pedal by carefully depressing and releasing the accelerator pedal (AP). Check that the value changes with accelerator pedal movement. The value must be between approximately 0.4 V when the accelerator pedal (AP) is unaffected and approximately 4 V when the accelerator pedal (AP) is fully depressed. The fault has been remedied if the values are OK.

Are these values OK?

  1. YES VERIFIED: Troubleshooting has been completed.
  2. NO Refer to «INFORMATION»(ref-476771-S02251460532012060500000)
