STEP 11. Check the CAN_H line (communication line only)
between joint connector (3) and ETACS-ECU 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 ETACS-ECU
connector C-218, 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 5 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 the
ETACS-ECU connector.

(3) Disconnect the negative battery terminal.
(4) Measure the resistance between joint connector (3)
terminal 6 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
NO : If the resistance measures less than 1 k
Ω, go to Step

STEP 13. Check A/C-ECU connector C-10 <manual air
conditioning system (low)> or C-15 <manual air
conditioning system (middle) or automatic air conditioning
system> 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: Is A/C-ECU connector C-10 <manual air conditioning
system (low)> or C-15 <manual air conditioning system
(middle) or automatic air conditioning system> in good
condition?
YES : Go to Step 14.
NO : Repair the damaged parts.
