Test Notes

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 diagnostic monitor (refer to Diagnostic Trouble Codes 41 and 42 diagnosis). The other wire is used for monitoring the mounting (ground) of the sensor to sheet metal (refer to Diagnostic Trouble Codes 44 and 45 diagnosis). If diagnosis reveals that BOTH primary sensors are not connected AND the primary sensors are not properly grounded, the diagnostic monitor will flash the air bag indicator continuously at a fast rate.

Possible Causes
1. Both primary crash sensors disconnected from wiring harness or main wiring harness not connected with engine compartment wiring harness.
