When checking the joint connector, ensure that its wiring harness side and its short pins are not damaged.
|
|
Q.
Is the check result normal?
|
|
Repair the defective connector. Replace the joint connector as necessary.
|
|
|
|
(1)Disconnect joint connector (CAN2) and the SRS-ECU connector, and measure at the wiring harness side.
|
|
(2)Turn the ignition switch to the LOCK (OFF) position.
|
|
(3)
caution |
When measuring the resistance, disconnect the negative battery terminal. For details refer to .
|
Ensure that the negative battery terminal is disconnected.
|
|
(4)Continuity between D-22 joint connector (CAN2) terminal No.3 and D-24 SRS-ECU connector terminal No.32 <3800, 3200> OK: Continuity (2 Ω or less)
|
|
(5)Continuity between D-22 joint connector (CAN2) terminal No.9 and D-24 SRS-ECU connector terminal No.43 <3800> OK: Continuity (2 Ω or less)
|
|
(6)Continuity between D-22 joint connector (CAN2) terminal No.14 and D-24 SRS-ECU connector terminal No.43 <3200> OK: Continuity (2 Ω or less)
caution |
Strictly observe the specified wiring harness repair procedure. For details refer to .
|
|
|
Q.
Is the check result normal?
|
|
<All the resistances measure 2 Ω or less> Power supply to the SRS-ECU may be suspected. Diagnose the SRS-ECU. Refer to GROUP 52B, Symptom procedure .
|
|
|
|
NO : <Either or all of the resistances measure more than 2 Ω> Repair the wiring harness between joint connector (CAN2) and the SRS-ECU connector.
