DIAGNOSIS

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

STEP 1. Check joint connector (CAN2) C-04, AWD-ECU
connector C-128 and intermediate connector C-31 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to P.54D-8.

Q:Are joint connector (CAN2) C-04, AWD-ECU connector

C-128 and intermediate connector C-31 in good

condition?

YES:

Go to Step 2.

NO:

Repair the damaged parts.

STEP 2. Check the wiring harness between joint connector
(CAN2) C-04 and AWD-ECU connector C-128.

Strictly observe the specified wiring harness repair
procedure. For details refer to P.54D-8.

(1)

Disconnect joint connector (CAN2) C-04 and AWD-ECU
connector C-301, and check the wiring harness.

(2)

Check the wiring harness between joint connector (CAN2)
C-04 (terminal No.5) and AWD-ECU connector C-128
(terminal No.5)

(3)

Check the wiring harness between joint connector (CAN2)
C-04 (terminal No.16) and AWD-ECU connector C-128
(terminal No.13)

Q:Is the wiring harness between joint connector (CAN2)

C-04 and AWD-ECU connector C-128 in good condition?

YES:

Check the power supply circuit of the AWD-ECU. Refer

to Group 27C, Multiselect AWD Diagnosis P.27C-74.

NO:

Repair the wiring harness between joint connector

(CAN2) C-04 and AWD-ECU connector C-128.
