1. Using the M-MDS, verify that no DTCs are stored. (See DTC INSPECTION [SAS CONTROL MODULE (ACTIVE BONNET)].)

2. Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data at that time, and detect the malfunction cause.

3. Shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for malfunction or occurrence of any DTCs.

Outline

• The OBD (on-board diagnostic) system has the following functions:

― Malfunction detection function: Detects malfunctions in the air bag system and outputs DTCs (Diagnostic Trouble Codes).

― PID/data monitor function: Reads out specific input/output signals and the system status.

• DTCs can be read/cleared using the M-MDS.

Note

• Use the M-MDS to verify DTCs because the DTCs displayed by the air bag system warning light are reference information only.
