STEP 2. Check the wiring harness between joint connector
(CAN3) C-127 and shift lever connector C-27.
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
(1) Disconnect joint connector (CAN3) C-127 and shift lever
connector C-27, and check the wiring harness.
(2) Check the wiring harness between joint connector (CAN3)
C-127 (terminal 7) and shift lever connector C-27 (terminal
2)
OK: Continuity exists (2
Ω or less)
(3) Check the wiring harness between joint connector (CAN3)
C-127 (terminal 20) and shift lever connector C-27 (terminal
1)
OK: Continuity exists (2
Ω or less)
Q: Is the wiring harness between joint connector (CAN3)
C-127 and shift lever connector C-27 in good condition?
YES : Check the power supply circuit of the shift lever. Refer
<shift
lever>.
NO : Repair the wiring harness between joint connector
(CAN3) C-127 and shift lever connector C-27.

.
FUNCTION
If the scan tool MB991958 cannot communicate with
the ASC-ECU, this diagnosis result will be set.
.
TROUBLE JUDGEMENT CONDITIONS
If a communication flag is not set for the ASC-ECU,
the ETACS-ECU determines that there is a failure.
.
TROUBLESHOOTING HINTS
• Malfunction of the connector [joint connector
(CAN3) or ASC-ECU connector improperly con-
nected]
• Malfunction of the wiring harness [open circuit
between the ASC-ECU and the joint connector
(CAN3), power supply circuit to the ASC-ECU]
• Malfunction of the ASC-ECU
DIAGNOSIS
Required Special Tools:
• MB991223: Harness Set
• MB992006: Extra Fine Probe
• MB991997: ASC Check Harness
STEP 1. Check joint connector (CAN3) C-127 and ASC-ECU
connector A-05 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-127 and ASC-ECU
connector A-05 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.
