(4) Measure the resistance between ABS-ECU connector

terminal 23 and powertrain control module connector

terminal 18.

OK: 2 ohms or less

(5) Measure the resistance between ABS-ECU connector

terminal 24 and powertrain control module connector

terminal 17.

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 12.

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 the
ABS-ECU connector and the powertrain control
module connector, and then go to Step 8.

STEP 12. Check the terminator resistor inside the
powertrain control module. Measure the resistance at

powertrain control module connector B-19.

CAUTION

A digital multimeter should be used. For details refer to

P.54C-4

.

(1) Disconnect powertrain control module connector B-19, and

measure the resistance at the component side of
powertrain control module connector B-19.

(2) Measure the resistance between powertrain control module

connector terminals 17 and 18.

OK: 120

± 20 Ω

Q: Does the resistance measure 120

± 20 Ω?

YES : If the resistance measures 120

± 20 Ω, go to Step 8.

NO : If the resistance does not measure 120

± 20 Ω,

replace the powertrain control module, and then go to
Step 8.

STEP 13. Check the CAN bus lines (communication line
only) between intermediate connector C-29 and the
ABS-ECU. Measure the resistance at 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 14.

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, and
then go to Step 8.
