Test F: DTCs B299C And B29A6 - Suppressor Left/Right Circuit Short to Ground - Loop #1

PINPOINT TEST F: DTCs B299C AND B29A6 - SUPPRESSOR LEFT/RIGHT CIRCUIT SHORT TO GROUND - LOOP #1

Normal Operation
The fire suppression module checks all of the fire suppressor circuits for faults. If the fire suppression module detects a short to ground on the LH fire suppressor squib 1 circuits, it stores DTC B299C in memory and illuminates the fire suppression system indicator. If the fire suppression module detects a short to ground on the RH fire suppressor squib 1 circuits, it stores DTC B29A6 in memory and illuminates the fire suppression system indicator.

DTC B299C (Suppressor Left Circuit Short to Ground - Loop #1) - sets when the fire suppression module detects a short to ground 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 B29A6 (Suppressor Right Circuit Short to Ground - Loop #1) - sets when the fire suppression module detects a short to ground 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
