Test Notes
WARNING: THE ELECTRICAL CIRCUIT NECESSARY FOR SYSTEM DEPLOYMENT IS POWERED DIRECTLY FROM THE BATTERY. TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE NEGATIVE BATTERY CABLE MUST BE DISCONNECTED PRIOR TO SERVICING OR REPLACING ANY SYSTEM COMPONENTS.
NORMAL OPERATION
Each primary crash sensor has three wires. Two of the wires are used for air bag deployment and monitoring the sensor's connection to the air bag diagnostic monitor. 41: Center Cowl Primary Crash Sensor Feed Circuit OpenThe other wire is used for monitoring the mounting (ground) of the primary crash sensor to sheet metal. 44: Center Cowl Primary Crash Sensor Mounted Incorrectly
If diagnosis reveals that BOTH primary crash sensors are not connected AND the primary crash sensors are not properly grounded, the air bag diagnostic monitor will flash the air bag indicator continuously at a fast rate.
POSSIBLE CAUSES
- All primary crash sensors disconnected from wiring harness or main wiring harness not connected with engine compartment wiring harness.
