disconnected.
(4) Continuity between joint connector (CAN-LO)
terminal No.6 and A/C-ECU connector terminal
No.32
OK: Continuity (2
Ω or less)
(5) Continuity between joint connector (CAN-LO)
terminal No.17 and A/C-ECU connector terminal
No.31
OK: Continuity (2
Ω or less)
CAUTION
Strictly observe the specified wiring harness
repair procedure. For details refer to
Q: Is the check result normal?
YES :
<All the resistances measure 2
Ω or less>
Power supply to the A/C-ECU may be
suspected. Diagnose the A/C. Refer to
GROUP 55
− Troubleshooting .
NO :
<Either or all of the resistances measure
more than 2
Ω> Repair the wiring harness
between joint connector (CAN-LO) and the
A/C-ECU connector.
Diagnosis Item 24: Diagnose when the M.U.T.-III cannot receive the data sent by electric tailgate
control unit <vehicles with electric tailgate>.
CAUTION
When servicing a CAN bus line, earth yourself by
touching a metal object such as an unpainted
water pipe. If you fail to do, a component con-
nected to the CAN bus line may be broken.
FUNCTION
The diagnostic result demonstrates that "the
M.U.T.-III cannot receive the sent data from the elec-
tric tailgate control unit" when the M.U.T.-III checks
the periodically sent data from each ECU and cannot
receive the electric tailgate control unit data only.
TROUBLE JUDGEMENT CONDITIONS
M.U.T.-III judges the trouble when the periodically
sent data from electric tailgate control unit cannot be
received.
PROBABLE CAUSES
• Damaged harness wires and connectors
• Power supply circuit malfunction of the electric
tailgate control unit
• Malfunction of the electric tailgate control unit
DIAGNOSIS PROCEDURE
STEP 1. Connector check: joint connector
(CAN-LO) and electric tailgate control unit
connector
CAUTION
The strand end of the twist wire should be within
10 cm from the connector. For details refer to
.
When checking the joint connector, ensure that its
wiring harness side and its short pins are not dam-
aged.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the defective connector. Replace the
joint connector as necessary.
STEP 2. Resistance measurement at joint
connector (CAN-LO) and electric tailgate control
unit connector.
CAUTION
A digital multimeter should be used. For details
refer to
CAUTION
The test wiring harness should be used. For
details refer to
.
(1) Disconnect joint connector (CAN-LO) and the
electric tailgate control unit connector, and
measure at the wiring harness side.
(2) Turn the ignition switch to the LOCK (OFF)
