Test Notes
NORMAL OPERATIONNote that Circuit 618 (P/LG) is grounded to the side of the RH primary crash sensor case and the case is grounded to the vehicle at its mounting point.
The air bag diagnostic monitor measures the resistance between Pin C276-20, Circuit 618 (P/LG) and Pin C277-3, Circuit 57 (BK), diagnostic monitor reference ground. If the air bag diagnostic monitor measures a difference of more than 2.0 ohms between Pin 276-20 and Pin C277-3, it will flash Diagnostic Trouble Code (DTC) 44.

POSSIBLE CAUSES
High resistance on Pin C276-20, Circuit 618 (P/LG) to ground can be caused by:
1. A poor connection due to loose mounting, dirt or corrosion at the RH primary crash front air bag sensor and bracket mounting location.
2. An open or damaged wire in Circuit 618 (P/LG) from Pin C276-20 of the air bag diagnostic monitor harness connector to RH primary crash sensor.
3. An open circuit inside RH primary crash sensor.
