Q.
Is the check result normal?
|
|
Repair the damaged connector.
|
|
|
|
(1)Disconnect the connector and measure at the wiring harness side.
|
|
(2)Turn the electric motor switch to the ON position.
|
|
(3)Measure the voltage between the E-06 MCU connector No.5 and the earth. OK: Battery voltage

|
|
|
|
Repair the wiring harness.
|
|
|
|
(1)Disconnect the connector and measure at the wiring harness side.
|
|
(2)Measure the resistance between the E-06 MCU connector terminal No. 10 and the body
earth. OK: Continuity exists (2 Ω or less)
