DIAGNOSIS
TSB Revision
CONTROLLER AREA NETWORK (CAN)
54C-89
.
FUNCTION
If the scan tool MB991958 cannot communicate with
the TCM, this diagnosis result will be set.
.
TROUBLE JUDGMENT CONDITIONS
If a communication flag is not set for the TCM, the
ETACS-ECU determines that there is a failure.
.
TROUBLESHOOTING HINTS
• Malfunction of the connector [joint connector
(CAN3) or TCM connector improperly connected]
• Malfunction of the wiring harness [open circuit
between the TCM and the joint connector
(CAN3), power supply circuit to the TCM]
• Malfunction of the TCM
DIAGNOSIS
Required Special Tools:
• MB991223: Harness Set
• MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN3) C-01 and TCM
connector C-38 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 (CAN3) C-01 and TCM connector
C-38 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.

STEP 2. Check the wiring harness between joint connector
(CAN3) C-01 and TCM connector C-38 for open circuit.
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
(1) Disconnect joint connector (CAN3) C-01 and TCM
connector C-38, and check the wiring harness.
(2) Check the wiring harness between joint connector (CAN3)
C-01 (terminal No.7) and TCM connector C-38 (terminal
No.4) <CVT>
OK: Continuity exists (2 ohms or less)
(3) Check the wiring harness between joint connector (CAN3)
C-01 (terminal No.20) and TCM connector C-38 (terminal
No.5) <CVT>
OK: Continuity exists (2 ohms or less)
(4) Check the wiring harness between joint connector (CAN3)
C-01 (terminal No.7) and TCM connector C-38 (terminal
No.10) <A/T>
OK: Continuity exists (2 ohms or less)
(5) Check the wiring harness between joint connector (CAN3)
C-01 (terminal No.20) and TCM connector C-38 (terminal
No.11) <A/T>
OK: Continuity exists (2 ohms or less)
Q: Is the wiring harness between joint connector (CAN3)
C-01 and TCM connector C-38 in good condition?
YES : Check the power supply circuit of the TCM. Refer to
GROUP 23A, Troubleshooting
GROUP 23C, Troubleshooting
NO : Repair the wiring harness between joint connector
(CAN3) C-01 and TCM connector C-38.
