STEP 21. Check the CAN_H line (communication line
including the multi-center display unit (middle-grade type))
between joint connector (3) and middle-grade multi-center
display connector for short to ground. Measure the
resistance at joint connector (3) C-02.
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 (3) C-02, and measure the
resistance at the wiring harness side of joint connector (3)
C-02.
(2) Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION
Disconnect the negative battery terminal. For details refer
to
.
(3) Disconnect the negative battery terminal.
(4) Measure the resistance between joint connector (3)
terminal 8 and body ground.
OK: 1 k
Ω or more
Q: Does the resistance measure 1 k
Ω or more?
YES : If the resistance measures 1 k
Ω or more, go to Step
24 .
NO : If the resistance measures less than 1 k
Ω, go to Step
22 .
STEP 22. Check multi-center display unit (middle-grade
type) connector C-05.
CAUTION
The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to
Q: Is multi-center display unit (middle-grade type)
connector C-05 in good condition?
YES : Go to Step 23.
NO : Repair the damaged parts.

C-02.
(2) Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION
Disconnect the negative battery terminal. For details refer
to
.
(3) Disconnect the negative battery terminal.
(4) Measure the resistance between joint connector (3)
terminal 8 and body ground.
OK: 1 k
Ω or more
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Does the resistance measure 1 k
Ω or more?
YES : If the resistance measures 1 k
Ω or more, diagnose
CAN bus lines thoroughly by referring to
NO : If the resistance measures less than 1 k
Ω, repair the
wiring harness between joint connector (3) and
multi-center display unit (middle-grade type)
connector.
