(4) Measure the resistance between intermediate connector

terminal 11 and ABS-ECU connector terminal 25.

OK: 2 ohms or less

(5) Measure the resistance between intermediate connector

terminal 12 and ABS-ECU connector terminal 7.

OK: 2 ohms or less

CAUTION

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

P.54C-5

.

Q: Do all the resistances measure 2 ohms or less?

YES : If all the resistances measure 2 ohms or less, go to

Step 3.

NO : If either of the resistances measures more than 2

ohms or all the resistances measure more than 2
ohms, repair the wiring harness between intermediate
connector C-29 and the ABS-ECU connector.

STEP 3. Check joint connector (3) C-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

.

Check the joint connector at the wiring harness side for loose,
corroded or damaged terminals, or terminals pushed back in
the connector, and also check the short pin behind the connec-
tor for corrosion, deformation and delamination.
Q: Is joint connector (3) C-02 in good condition?

YES : Go to Step 4.
NO : Repair the damaged parts. Replace the joint

connector as necessary.

STEP 4. Check the CAN bus lines between intermediate
connector C-29 and the joint connector (3). Measure the
resistance between intermediate connector C-29 and 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 intermediate

connector C-29, and measure the resistance between the
wiring harness side connector of joint connector (3) C-02
and the female side connector of intermediate connector
C-29 (instrument panel 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.

(4) Measure the resistance between intermediate connector

terminal 12 and joint connector (3) terminal 20.

OK: 2 ohms or less

(5) Measure the resistance between intermediate connector

terminal 11 and joint connector (3) terminal 9.

OK: 2 ohms or less

CAUTION

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

P.54C-5

.

Q: Do all the resistances measure 2 ohms or less?

YES : If all the resistances measure 2 ohms or less, power

supply to the ABS-ECU may be suspected. Diagnose
the ABS system. Refer to GROUP 35B ABS
diagnosis

P.35B-84

.

NO : If either of the resistances measures more than 2

ohms or all the resistances measure more than 2
ohms, repair the wiring harness between joint
connector (3) and intermediate connector C-29.
