Inspection Procedure 3: SRS warning lamp does not illuminate.
OPERATION
- The SRS warning lamp illuminates when the ignition switch is turned to the "ON" position and goes out after approximately 6 to 8 seconds if there is not a malfunction in the SRS system.
- SRS-ECU sends the SRS warning lamp signal to the combination meter via the CAN communication.
- As a cause, the failure of CAN bus line, combination meter, or SRS-ECU is suspected.
PROBABLE CAUSES
- Damaged wiring harness and connectors
- Combination meter malfunction
- Malfunction of SRS-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
STEP 2. M.U.T.-IIISE actuator test
Use M.U.T.-IIISE to perform the SRS-ECU actuator tests.Item No. 01: SRS warning lamp
