Non-Trouble Code Procedures
CENTRAL TIMER MODULE
WARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE
SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, SEAT
BELT TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE
PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL
RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG
DEPLOYMENT.
The hard wired inputs to and outputs from the central timer module (CTM) may be diagnosed and tested using conventional diagnostic tools and
methods. Refer to the appropriate wiring information.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM. In order to obtain conclusive testing of the CTM, the
programmable communications interface (PCI) data bus network and all of the modules that provide inputs to or receive outputs from the CTM must also
be checked. The most reliable, efficient, and accurate means to diagnose the CTM, the PCI data bus network, and the modules that provide inputs to, or
receive outputs from, the CTM requires the use of a DRBIII(R) scan tool. Refer to the appropriate diagnostic information.
