Test I: DTCs B299E and B29A8 - Suppressor Left/Right Circuit Resistance Low on Squib - Loop #1

PINPOINT TEST I: DTCS B299E AND B29A8 - SUPPRESSOR LEFT/RIGHT CIRCUIT RESISTANCE LOW ON SQUIB - LOOP #1

I1-I3:

I3-I5:

I6:

Normal Operation
he fire suppression module (FSM) checks all of the fire suppressors circuits for faults. If the FSM detects a low resistance condition between the LH fire suppressor squib 1 circuits, it stores DTC B299E in memory and illuminates the fire suppression system indicator. If the FSM detects a low resistance condition between the RH fire suppressor squib 1 circuits, it stores DTC B29A8 in memory and illuminates the fire suppression system indicator.

Possible Causes
- circuit 2312 (LG) short to circuit 2313 (BK/WH)
- circuit 2310 (OG) short to circuit 2311 (DG)
- LH fire suppressor
- RH fire suppressor
- FSM
