52 -INTERIOR AND SUPPLEMENTAL RESTRAINT SYSTEM(SRS) > 52B-SUPPLEMENTAL RESTRAINT SYSTEM (SRS) > TROUBLESHOOTING > SYMPTOM PROCEDURES > AFTER THE IGNITION SWITCH IS TURNED TO "ON", THE SRS WARNING LAMP DOES NOT GO OUT.
Inspection Procedure 4: The SRS warning lamp does not go out.
 
 
 
 
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
 
 
DIAGNOSTIC PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 2
Repair the CAN bus lines (refer to Group 54C - Troubleshooting ).
 
STEP 2. Recheck of the SRS warning lamp
(1) Connect the negative battery terminal.
(2) Ignition switch: ON
Does the SRS warning light illuminate for approximately 6 to 8 seconds and then go out after the ignition switch is turned to the "ON" position?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
Go to Step 3
 
STEP 3. M.U.T.-IIISE special function
Use M.U.T.-IIISE to perform the combination meter special function (Refer to GROUP 54A - Combination Meter - Special function table ).
  • Item No. 9: Indicator (AUTO)
Does the SRS warning lamp turn on and off normally?
Go to Step 4.
Replace the combination meter (Refer to GROUP 54A - Combination Meter - Combination meter ).
 
STEP 4. Check the diagnosis code.
After erasing the diagnosis code memory, check the diagnosis code.
Is the diagnosis code set?
Troubleshoot for the relevant diagnosis code. (Refer to .)
Go to Step 5.
 
STEP 5. Recheck of the SRS warning lamp
Does the lamp stay ON?
Replace the SRS-ECU (Refer to ).
This diagnosis is complete.
