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

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

Normal Operation
The fire suppression module checks all of the fire suppressors circuits for faults. If the fire suppression module 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 fire suppression module 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.

DTC B299E (Suppressor Left Circuit Resistance Low on Squib - Loop #1) - sets when the fire suppression module detects a low resistance condition on the left fire suppressor squib 1 circuits 2312 (LG) and 2313 (BK/WH). This DTC will cause the fire suppression system indicator to illuminate.

DTC B29A8 (Suppressor Right Circuit Resistance Low on Squib - Loop #1) - sets when the fire suppression module detects a low resistance condition on the right fire suppressor squib 1 circuits 2310 (OG) and 2311 (DG). This DTC will cause the fire suppression system indicator to illuminate.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH fire suppressor
- RH fire suppressor
- Fire suppression module
