Description and Operation
For a detailed description of the multifunction electronic control modules, refer to the relevant Description and Operation
section in the workshop manual.
REFER to:
Module Controlled Functions
(419-10 Multifunction Electronic Modules, Description and Operation).
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.
1.
2. Visually inspect for obvious signs of electrical damage.

Fuse(s)
Electrical connector(s)

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before
proceeding to the next step.
3.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
4.
DTC Index
• NOTE: If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the W arranty 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.
• NOTE: The DTC Index in this section shows information for DTCs that could be logged in the Driver Door Module (DDM) or
Passenger Door Module (PDM). For diagnosis and testing information for: Driver Seat module.
REFER to:
Seats
(501-10 Seating, Diagnosis and Testing).
Information and Entertainment module.
REFER to:
Information and Entertainment System
(415-01 Information and Entertainment System, Diagnosis and Testing).
• 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 additional
information read by the manufacturer approved diagnostic system).
• NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three
decimal places, and with an up-to-date calibration certificate. When 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.
