1. SRS system check
2. Far side airbag circuit resistance check
1) Observe the Far Side Airbag Loop Resistance parameter on the scan tool. Is the Far Side Airbag Loop Resistance parameter less than or equal to the specified value?
Value: 1 Ω
Yes
=>Go to Connection check for far side airbag harness connector.
No
Go to Intermittent conditions of SRS control.
Refer to "209.Restraints 22D.Symptom Intermittent conditions of SRS control".
3. Connection check for far side airbag harness connector
1) Verify that the far side airbag harness connector (R60) is securely connected. Is the far side airbag harness connector (R60) securely connected?
Refer to "RHD SRS airbag (Driver/Passenger/Side/Curtain/Knee/Far Side)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Far side airbag harness connector inspection.
No
Securely connect the far side airbag harness connector (R60).
4. Far side airbag harness connector inspection
1) Disconnect the far side airbag harness connector (R60).
2) Inspect the far side airbag harness connector terminals (pins 1 and 2 of R60) for bending, dirt, etc. Is the result normal?
Refer to "RHD SRS airbag (Driver/Passenger/Side/Curtain/Knee/Far Side)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
No
Repair the connections as necessary.
5. Current DTC check
1) Connect the far side airbag harness connector (R60).
Refer to "RHD SRS airbag (Driver/Passenger/Side/Curtain/Knee/Far Side)" in the ETM (wiring diagram). (Open using the ETM viewer.).
2) Turn ON the ignition switch.
3) Observe the DTC information with a scan tool for DTC B1E1A[1A] being set as a current failure. Is a DTC set?
Yes
=>Go to Far side airbag circuit check.
No
6. Far side airbag circuit check
1) Turn OFF the ignition switch for 15 seconds or more.
2) Disconnect the far side airbag harness connector (R60).
3) Connect the SRS alternative load and SRS adapter for load tool to the far side airbag harness connector (R60).
Refer to "RHD SRS airbag (Driver/Passenger/Side/Curtain/Knee/Far Side)" in the ETM (wiring diagram). (Open using the ETM viewer.).
SST: 5-8840-3269-0 - SRS adapter for load tool
SST: 5-8840-2856-0 - SRS alternative load
4) Turn ON the ignition switch.
5) Observe the DTC information with a scan tool for DTC B1E1A[1A] being set as a current failure. Is a DTC set?
Yes
=>Go to Inspection for short circuit in far side airbag circuit.
No
Replace the far side airbag.
Refer to "8.Restraints 8B.Airbag Systems far side air bag removal".
Refer to "8.Restraints 8B.Airbag Systems far side air bag installation".
7. Inspection for short circuit in far side airbag circuit
1) Turn OFF the ignition switch for 15 seconds or more.
2) Inspect for a short together between the far side airbag deployment current output (High) circuit and the far side airbag deployment current output (Low) circuit between the SRS control unit (pins 14 and 13 of R6) and the far side airbag (pins 1 and 2 of R60). Is the result normal?
Refer to "RHD SRS airbag (Driver/Passenger/Side/Curtain/Knee/Far Side)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to SRS control unit replacement.
No
Repair the circuit as necessary.
8. SRS control unit replacement
Note
- Perform the VIN programming and ECU lock after replacing the SRS control unit.
Refer to "8.Restraints 8Z.Seat Belt and SRS Airbag Electrical Control SRS control unit removal".
Refer to "8.Restraints 8Z.Seat Belt and SRS Airbag Electrical Control SRS control unit installation".
Refer to "8.Restraints 8Z.Seat Belt and SRS Airbag Electrical Control SRS control unit setting".
Procedure completion
9. Repair verification
1) Reconnect all of the disconnected harness connectors.
2) Clear the DTC with a scan tool.
3) Turn OFF the ignition switch for 15 seconds or more.
4) Turn ON the ignition switch.
5) Observe the DTC information with a scan tool.
