STEP 2. Check the wiring harness between joint connector
(CAN2) C-04 and AWD-ECU connector C-128 for open
circuit.
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
(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)
OK: Continuity exists (2 ohms or less)
(3) Check the wiring harness between joint connector (CAN2)
C-04 (terminal No.16) and AWD-ECU connector C-128
(terminal No.13)
OK: Continuity exists (2 ohms or less)
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
.
NO : Repair the wiring harness between joint connector
(CAN2) C-04 and AWD-ECU connector C-128.

FUNCTION
If the scan tool MB991958 cannot communicate with
the AWC-ECU, this diagnosis result will be set.
.
TROUBLE JUDGMENT CONDITIONS
If a communication flag is not set for the AWC-ECU,
the ETACS-ECU determines that there is a failure.
.
TROUBLESHOOTING HINTS
• Malfunction of the connector [joint connector
(CAN2) or AWC-ECU connector improperly con-
nected]
• Malfunction of the wiring harness [open circuit
between the AWC-ECU and the joint connector
(CAN2), power supply circuit to the AWC-ECU]
• Malfunction of the AWC-ECU
DIAGNOSIS
Required Special Tools:
• MB991223: Harness Set
• MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN2) C-04, AWC-ECU
connector C-139, intermediate connector C-138 and
intermediate connector C-31 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
CAUTION
The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to
Q: Are joint connector (CAN2) C-04, AWC-ECU connector
C-139, intermediate connector C-138 and intermediate
connector C-31 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.
