Chart F Tech 1 Cannot Communicate With SRS









CIRCUIT DESCRIPTION
When system voltage is applied to the center sensor assembly, it will perform the "Primary Check" followed by the "Constant Check." When a fault is detected, the center sensor assembly will store a DTC and illuminate the air bag indicator. When a DTC is stored. the safety circuit (inside the center sensor assembly) will open, preventing SRS operation. All faults must be repaired and all DTCs must be cleared before the safety circuit closes, allowing the SRS to function normally.

TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. An improper connection to the DLC will prevent communication from being established.
2. This test confirms proper center sensor assembly operation.
3. This test determines whether the fault is due to an open in the AB CKT or junction block 1.
