General Information - Diagnostic Trouble Code (DTC) Index DTC: Restraints
Control Module (RCM)
Description and Operation

Restraints Control Module (RCM)

WARNINGS:


TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED
BEFORE REPAIRING OR REPLACING ANY AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS. TO DEPLETE THE
BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT ONE MINUTE. FAILURE TO FOLLOW
THIS INSTRUCTION MAY RESULT IN PERSONAL INJURY


Do not use a multimeter to probe the restraints control module. It is possible for the power from the meter battery to
trigger the activation of the airbags. Failure to follow this instruction may result in personal injury


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.


It is advisable not to use a cellular phone or to have a cellular phone in close proximity when working on the restraints
control module or associated systems.


Given the legal implications of a restraints system failure, harness repairs to air bag module circuits are not acceptable.
Where the text refers to "REPAIR the circuit", this will normally mean the replacement of a harness.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Restraints Control Module (RCM). For
additional diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop manual.
