Test J: LFC 33/DTC B1933 - Passenger Air Bag Resistance High

J1:

J1 - J2:

J2 - J3:

J4 - J5:

Normal Operation
The Restraints Control Module (RCM) monitors the resistance of the passenger air bag ignitor by measuring the resistance between pins 6 and 7. If the RCM detects high resistance between these pins, it will store a Diagnostic Trouble Code (DTC) B1933 in memory and flash a Lamp Fault Code (LFC) 33 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
A passenger air bag high resistance could be caused by:
^ wiring, terminals, or connectors.
^ an open circuit or high resistance in the passenger air bag module.
^ an RCM internal concern.
