General Information - Diagnostic Trouble Code (DTC)

Index DTC: Engine Control Module (PCM)

Description and Operation
Engine Control Module (ECM)

CAUTION: Diagnosis by substitution from a donor vehicle

is NOT acceptable. Substitution of control modules does not guarantee
confirmation of a fault, and may also cause additional faults in the vehicle being
tested and/or the donor vehicle.

NOTES:

If a control module or a component is suspect and the vehicle remains

under manufacturer warranty, refer to the Warranty Policy and Procedures
manual, or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.

Generic scan tools may not read the codes listed, or may read only 5-digit
codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit
code listed to identify the fault (the last 2 digits give extra information read by
the manufacturer-approved diagnostic system).

When performing voltage or resistance tests, always use a digital

multimeter accurate to three decimal places, and with an up-to-date calibration
certificate. When testing resistance always take the resistance of the digital
multimeter leads into account.

Check and rectify basic faults before beginning diagnostic routines

involving pinpoint tests.

Inspect connectors for signs of water ingress, and pins for damage and/or
corrosion.

If DTCs are recorded and, after performing the pinpoint tests, a fault is not
present, an intermittent concern may be the cause. Always check for loose
connections and corroded terminals.

Check DDW for open campaigns. Refer to the corresponding bulletins and
SSMs which may be valid for the specific customer complaint and carry out the
recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged
in the Engine Control Module (ECM). For additional diagnosis and testing
information, refer to the relevant Diagnosis and Testing section in the workshop
manual.
For additional information, refer to: Engine (303-01 Engine - ID4 2.4L Diesel,
