Issue:
This bulletin provides information on Flash Codes and PID code descriptions to assist in
the diagnosis of the SRS.
This document is to be used as a guide only. It supports the existing diagnostic
equipment, circuit diagrams in the Electrical Guide, and workshop manual.
Action:
FLASH CODES
Determine any Flash Code(s) that may be stored in the Restraint Control Module (RCM)
by observing the SRS warning indicator displayed on the instrument cluster.
Note: Only one Flash Code will be displayed at a time, however there
may be multiple fault codes stored, which can appear after one fault
is repaired.
DTC & PID CODES
Retrieve any logged Diagnostic Trouble Codes (DTCs) from the Restraint Control
Module (RCM) using the Worldwide Diagnostic System (WDS).
Note: The Parameter Identification (PID) code, which is displayed on
the WDS screen in brackets next to the DTC, differs from the Flash
Code. These two codes must not be confused as incorrect diagnosis
may occur.
DIAGNOSIS
WARNING: ENSURE ALL SAFETY PROCEDURES ARE
FOLLOWED BEFORE AND DURING ANY WORK THAT IS
CARRIED OUT ON THE SRS.
Using the Index, retrieved Flash Code, retrieved DTCs and PID codes determine the
correct fault description. Check the list of possible causes against that fault description
