STEP 7. Check the CAN bus lines (communication line
only) between intermediate connector C-29 and joint
connector (3). Measure the resistance at 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, go to

Step 2.

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 the intermediate connector, and
then go to Step 2.

STEP 8. Check the front wiring harness side CAN bus lines
(communication line including the powertrain control
module and the ABS-ECU). 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 measure the

resistance at the male side (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

terminals 11 and 12.

OK: 120

± 20 Ω

Q: Does the resistance measure 120

± 20 Ω?

YES : If the resistance measures 120

± 20 Ω, go to Step 15.

NO : If the resistance does not measure 120

± 20 Ω, go to

Step 9 .

STEP 9. Check ABS-ECU connector A-02 and powertrain
control module connector B-19 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: Are ABS-ECU connector A-02 and powertrain control

module connector B-19 in good condition?
YES : Go to Step 10.
NO : Repair the damaged parts. Then go to Step 8.
