When checking the joint connector, ensure that its wiring harness side and its short pins
are not damaged.
Q.
Is the check result normal?
Go to Step 2
Repair the defective connector. Replace the joint connector as necessary.
|
|
(1)Disconnect the joint connector (CAN2) and the BMU connector, and measure at the
wiring harness side.
|
|
(2)Turn the electric motor switch to the LOCK (OFF) position.
|
|
(3)
caution |
When measuring the resistance, disconnect the negative auxiliary
battery terminal. For details refer to .
|
Ensure that the negative auxiliary battery terminal is disconnected.
|
|
(4)Continuity between C-103 joint connector (CAN2) terminal No.9 and C-107 BMU connector
terminal No.6 OK: Continuity (2 Ω or less)
|
|
(5)Continuity between C-103 joint connector (CAN2) terminal No.20 and C-107 BMU connector
terminal No.7 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> Go to Step
3.
<Either or all of the resistances measure more than 2 Ω> Repair
the wiring harness between joint connector (CAN2) and the BMU connector.
|
|
(1)Remove the BMU, and measure at the equipment side.
|
|
(2)Resistance between C-107 BMU connector terminal Nos.6 and 7 OK: 1 kΩ or more
Q.
Is the check result normal?
<1 kΩ or more> Power supply to the BMU may be suspected.
Diagnose the BMU. Refer to .
<Less than 1 kΩ > Replace the BMU.
