Code No. B1519: SRS-ECU Connector Lock Out of Order
 
 
cautionIf diagnosis code B1519 is set in the SRS-ECU, always diagnose the CAN main bus line.
 
 
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set if a poor connection at the SRS-ECU is detected.
 
 
PROBABLE CAUSES
  • Damaged connectors
  • Malfunction of the SRS-ECU
 
 
DIAGNOSIS 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 line (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set.
(1) Erase the diagnosis code.
(2) Ignition: "LOCK" (OFF) position to "ON"
(3) On completion, check that the diagnosis code is not set again.
Is the diagnosis code set?
Go to Step 3.
There is an intermittent malfunction such as poor engaged connector(s) or open circuit (Refer to GROUP 00, How to Cope with Intermittent Malfunction ).
 
STEP 3. Connector check: SRS-ECU connector
Are connectors correctly engaged?
Go to Step 4.
Engage the connectors correctly.
 
STEP 4. Connector check: SRS-ECU harness side connector.
(1) Disconnect the negative battery terminal.
(2) Disconnect SRS-ECU harness side connectors.
 
(3) Check the connector lock switch terminal inside the harness side connector for improper contact or deformation.
Are the SRS-ECU harness side connector in good condition?
Erase the diagnosis code from memory, and check the diagnosis code. If diagnosis code B1519 sets, replace the SRS-ECU (Refer to ).
Replace the SRS-ECU connector (Refer to ).
