STEP 24. Check the CAN_H line (communication line only)
between joint connector (3) and the data link connector for
a short to the power supply. Measure the voltage 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 measure the
voltage at the wiring harness side of joint connector (3)
C-02.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between joint connector (3) terminal 7
and body ground.
OK: 1.0 V or less
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Does the voltage measure 1.0 V or less?
YES : If the voltage measures 1.0 V or less, go to Step 25.
NO : If the voltage measures more than 1.0 V, 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 a short to the power supply. Measure the voltage 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 intermediate connector C-29 and joint
connector (3) C-02, and measure the voltage at the wiring
harness side of joint connector (3) C-02.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between joint connector (3) terminal 9
and body ground.
OK: 1.0 V or less
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Does the voltage measure 1.0 V or less?
YES : If the voltage measures 1.0 V or less, diagnose CAN
bus lines thoroughly by referring to
NO : If the voltage measures more than 1.0 V, 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
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 a short to the power supply. Measure the
voltage at intermediate connector C-29.
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 intermediate connector C-29 and ABS-ECU
connector A-02, and measure the voltage at the male side
of intermediate connector C-29 (at front wiring harness
side).
(2) Turn the ignition switch to the "ON" position.
