CIRCUIT DESCRIPTION

1. Functional readiness of the firing circuit activation transistors.

2. Adequacy of deployment energy reserves.

3. Safing sensor integrity : detection of faulty closure.

4. Plausibility of accelerometer signal.

5. Operation of SRSCM components.

DIAGNOSIS WITH SCAN TOOL

CHECK PROCEDURES

1. Connect the Hi-Scan Pro DLC to the vehicle's data link connector located under neath the dash panel.

2. Turn the ignition key to the "ON" position and turn the Hi-Scan Pro ON.

3. Perform the SRS diagnosis according to the vehicle model configuration.

4. If a fault code is assured, then replace the component. Never attempt to repair the component.

5. If the Hi-Scan Pro finds that a component of the system is faulty, there is a possibility that the fault is not in the

component, but in SRS wiring or connector.
