Test J: DTC B2792 - Cross Link Between Firing Loops

PINPOINT TEST J: DTC B2792 - CROSS LINK BETWEEN FIRING LOOPS


J1-J2:






J2-J6:






Normal Operation
The fire suppression module (FSM) monitors all of the firing loops circuits for a cross-link between the circuits of another firing loop. If the FSM detects a short between the circuits of a firing loop and another firing loop, it stores a diagnostic trouble code (DTC) B2792 in memory and illuminates the fire suppression system indicator.

Possible Causes
- short circuit between firing loops
- LH fire suppressor
- RH fire suppressor
- FSM
