Test G: DTCs B29A1, B29AB, B29A3 And B29AD - Suppressor Left/Right Circuit Short To Ground/Low Resistance -Loop #2

PINPOINT TEST G: DTCs B29A1, B29AB, B29A3 AND B29AD - SUPPRESSOR LEFT/RIGHT CIRCUIT SHORT TO GROUND/LOW RESISTANCE -LOOP #2

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 2 circuits, it stores DTC B29A1 in memory and illuminates the fire suppression system indicator. If the fire suppression module detects a low resistance condition between the LH fire suppressor squib 2 circuits, it stores DTC B29A3 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 2 circuits, it stores DTC B29AB 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 2 circuits, it stores DTC B29AD in memory and illuminates the fire suppression system indicator.

DTC B29A1 (Suppressor Left Circuit Short to Ground - Loop #2) - sets when the fire suppression module detects a short to ground on the left fire suppressor squib 2 circuits 2328 (OG) and 2329 (DG). This DTC will cause the fire suppression system indicator to illuminate.

DTC B29AB (Suppressor Right Circuit Short to Ground - Loop #2) - sets when the fire suppression module detects a short to ground on the right fire suppressor squib 2 circuits 2326 (LG) and 2327 (BK/WH). This DTC will cause the fire suppression system indicator to illuminate.

DTC B29A3 (Suppressor Left Circuit Resistance Low on Squib - Loop #2) - sets when the fire suppression module detects a low resistance condition on the left fire suppressor squib 2 circuits 2328 (OG) and 2329 (DG). This DTC will cause the fire suppression system indicator to illuminate.

DTC B29AD (Suppressor Right Circuit Resistance Low on Squib - Loop #2) - sets when the fire suppression module detects a low resistance condition on the right fire suppressor squib 2 circuits 2326 (LG) and 2327 (BK/WH). This DTC will cause the fire suppression system indicator to illuminate.

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