Test F: DTCs B299B and B29A5 - Suppressor Left/Right Circuit Short to Battery - Loop #1

PINPOINT TEST F: DTCS B299B AND B29A5 - SUPPRESSOR LEFT/RIGHT CIRCUIT SHORT TO BATTERY - LOOP #1

F1-F3:

Normal Operation
The fire suppression module (FSM) checks all of the fire suppressor circuits for faults. If the FSM detects a short to voltage on the LH fire suppressor squib 1 circuits, it stores diagnostic trouble code (DTC) B299B in memory and illuminates the fire suppression system indicator. If the FSM detects a short to voltage on the RH fire suppressor squib 1 circuits, it stores diagnostic trouble code (DTC) B29A5 in memory and illuminates the fire suppression system indicator.

Possible Causes
- circuit 2310 (OG) short to voltage
- circuit 2311 (DG) short to voltage
- circuit 2312 (LG) short to voltage
- circuit 2313 (BK/WH) short to voltage
- FSM
