DTC 33 - Pin 7 Not Grounded at Diagnostic Monitor

If Pin 7 is not grounded, the diagnostic monitor will flash Diagnostic Trouble Code 33 on the air bag indicator.

Possible Causes
A high resistance or open in the passenger side air bag circuit can be caused by:
1. Pin 7 not connected to ground. The wire in pin location 7 in the Black diagnostic monitor harness connector should be connected to ground.
