STEP 46. 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 47.
NO : Repair the damaged parts.

STEP 47. Check the CAN_L line (communication line only)
between intermediate connector C-29 and ABS-ECU
connector for short to ground. Measure the resistance 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 resistance at the male
side 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
.
(3) Disconnect the negative battery terminal.
(4) Measure the resistance between intermediate connector
terminal 12 and body ground.
OK: 1 k
Ω or more
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Does the resistance measure 1 k
Ω or more?
YES : If the resistance measures 1 k
Ω or more, go to Step
48 .
NO : If the resistance measures less than 1 k
Ω, repair the
wiring harness between intermediate connector C-29
and ABS-ECU connector.

STEP 48. Check the CAN_L line (communication line only)
between the powertrain control module connector and
ABS-ECU connector for short to ground. Measure the
resistance at powertrain control module connector B-19.
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 powertrain control module connector B-19 and

B-19.
(2) Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION
Disconnect the negative battery terminal. For details refer
to
.
(3) Disconnect the negative battery terminal.
