STEP 25. Check the CAN bus lines between intermediate
connector C-29 and the ABS-ECU. Measure the resistance
between intermediate connector C-29 and ABS-ECU
connector A-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 intermediate connector C-29 and ABS-ECU

connector A-02, and measure the resistance between the
wiring harness side connector of ABS-ECU connector A-02
and the male side connector 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.

(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 26.

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 26. 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

(4) Measure the resistance between intermediate connector

terminal 11 and joint connector (3) terminal 9.

OK: 2 ohms or less

(5) Measure the resistance between intermediate connector

terminal 12 and joint connector (3) terminal 20.

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-82

.

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.
