Inspection and Verification

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.

1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage and system integrity.

DTC Index

• NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior

to the installation of a new module/component.

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

• NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places and with a current calibration certificate. W hen testing resistance, always take the resistance of the DMM leads into
account.

• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

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

• NOTE: 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.
