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 (CAN1) and the ABS-ECU <vehicles without ASC> or
ASC-ECU <vehicles with ASC> 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 joint connector (CAN1) terminal No.9 and ABS-ECU <vehicles
without ASC> or ASC-ECU <vehicles with ASC> connector terminal No.11 OK: Continuity (2 Ω or less)
|
|
(5)Continuity between joint connector (CAN1) terminal No.20 and ABS-ECU <vehicles
without ASC> or ASC-ECU <vehicles with ASC> connector terminal No.10 OK: Continuity (2 Ω or less)
|
|
Q.
Is the check result normal?
|
|
<All the resistances measure 2 Ω or less> Power supply
to the ABS-ECU <vehicles without ASC> or ASC-ECU <vehicles with ASC> may be suspected. Diagnose
the ABS <vehicles without ASC> Refer to GROUP 35B - Troubleshooting ,
or ASC <vehicles with ASC> Refer to GROUP 35C - Troubleshooting .
|
|
|
|
NO : <Either or all of the resistances measure more than 2 Ω> Repair
the wiring harness between joint connector (CAN1) and the ABS-ECU <vehicles without ASC>
or ASC-ECU <vehicles with ASC> connector.
