(3) Measure the voltage between intermediate connector
terminal 11 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 and
the powertrain control module connector.
STEP 24. Check intermediate connector C-29 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 intermediate connector C-29 in good condition?
YES : Go to Step 25.
NO : Repair the damaged parts.

STEP 25. Check the CAN_L-side bus line (communication
line including) of the front wiring harness 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 measure the
voltage at the male side (at front wiring harness side).
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between intermediate connector
terminal 12 and body ground.
OK: 4.0 V or less
Q: Does the voltage measure 4.0 V or less?
YES : If the voltage measures 4.0 V or less, go to Step 26.
NO : If the voltage measures more than 4.0 V, go to Step
43.

STEP 26. 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
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 27.
NO : Repair the damaged parts. Replace the joint
connector as necessary.

STEP 27. Check the CAN_L line (communication line
including the combination meter) between joint connector
(3) and the combination meter connector for a short to the
power supply. Measure the voltage at joint connector (3)
C-02.
CAUTION

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between joint connector (3) terminal
15 and body ground.
OK: 4.0 V or less
Q: Does the voltage measure 4.0 V or less?
YES : If the voltage measures 4.0 V or less, go to Step 29.
NO : If the voltage measures more than 4.0 V, go to Step
28.
