STEP 24. Check the CAN_H line (communication line only)
between joint connector (3) and the data link 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

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to

P.54C-4

.

(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

P.54C-4

.

(3) Disconnect the negative battery terminal.

(4) Measure the resistance between joint connector (3)

terminal 7 and body ground.

OK: 1 k

Ω or more

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to

P.54C-5

.

Q: Does the resistance measure 1 k

Ω or more?

YES : If the resistance measures 1 k

Ω or more, go to Step

25 .

NO : If the resistance measures less than 1 k

Ω, repair the

wiring harness between joint connector (3) and the
data link connector.

STEP 25. Check the CAN_H line (communication line only)
between intermediate connector C-29 and joint connector
(3) 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

P.54C-4

.

(1) Disconnect intermediate connector C-29 and 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

P.54C-4

.

(3) Disconnect the negative battery terminal.

(4) Measure the resistance between joint connector (3)

terminal 9 and body ground.

OK: 1 k

Ω or more

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to

P.54C-5

.

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

P.54C-520

.

NO : If the resistance measures less than 1 k

Ω, repair the

wiring harness between intermediate connector C-29
and joint connector (3).

STEP 26. Check ABS-ECU connector A-02 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

P.54C-4

.

Q: Is ABS-ECU connector A-02 in good condition?

YES : Go to Step 27.
NO : Repair the damaged parts.

STEP 27. Check the CAN_H line (communication line only)
between intermediate connector C-29 and ABS-ECU
connector for short to ground. Measure the resistance at
intermediate connector C-29.

CAUTION

A digital multimeter should be used. For details refer to

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to

P.54C-4

.

(1) Disconnect intermediate connector C-29 and ABS-ECU

connector A-02, and measure the resistance at the male
side of intermediate connector C-29 (at front wiring harness
side).

(2) Turn the ignition switch to the "LOCK" (OFF) position.

CAUTION

Disconnect the negative battery terminal. For details refer
to

P.54C-4

.

(3) Disconnect the negative battery terminal.
