Test E: DTCs B299F and B29A9 - Suppressor Left/Right Circuit Open - Loop #2

PINPOINT TEST E: DTCS B299F AND B29A9 - SUPPRESSOR LEFT/RIGHT CIRCUIT OPEN - LOOP #2

E1-E2:

E3-E4:

Normal Operation
The fire suppression module (FSM) checks all of the fire suppressor circuits for faults. If the FSM detects an open on the LH fire suppressor squib 2 circuits, it stores DTC B299F in memory and illuminates the fire suppression system indicator. If the FSM detects an open on the RH fire suppressor squib 2 circuits, it stores diagnostic trouble code (DTC) B29A9 in memory and illuminates the fire suppression system indicator.

Possible Causes
- circuit 2328 (OG) open
- circuit 2329 (DG) open
- circuit 2326 (LG) open
- circuit 2327 (BK/WH) open
- RH fire suppressor
- LH fire suppressor
- FSM
