STEP 20. Check the wiring harness between joint
connector (CAN1) C-103 and CAN box unit connector C-13
for a short to power supply. Measure the voltage at joint
connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and measure the

voltage at the wiring harness side of joint connector
(CAN1).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN1)

terminal 10 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN1)

terminal 23 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES (vehicles without satellite radio) : Go to Step 22.
YES (vehicles with satellite radio) : Go to Step 21.
NO : Go to Step 51.

STEP 21. Check the wiring harness between joint
connector (CAN1) C-103 and satellite radio tuner
connector C-111 for a short to power supply. Measure the
voltage at joint connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and measure the

voltage at the wiring harness side of joint connector
(CAN1).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN1)

terminal 3 and body ground.

OK: 4.7 volts or less

(4) Measure the voltage between joint connector (CAN1)

terminal 14 and body ground.

OK: 4.7 volts or less

Q: Do all the voltages measure 4.7 volts or less?

YES : Go to Step 22.
NO : Go to Step 52.

STEP 22. Check the wiring harness between joint
connector (CAN1) C-103 and ETACS-ECU connector C-301
for a short to power supply. Measure the voltage at joint
connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1) and ETACS-ECU

connector C-301, and measure the voltage at the wiring
harness side of joint connector (CAN1).

(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN1)

terminal 6 and body ground.

OK: 1.0 volts or less

(4) Measure the voltage between joint connector (CAN1)

terminal 19 and body ground.

OK: 1.0 volts or less

Q: Do all the voltages measure 1.0 volts or less?

YES : Go to Step 53.
NO : Repair the wiring harness between joint connector

(CAN1) C-103 and ETACS-ECU connector C-301.

STEP 23. Check the wiring harness for line-to-line short.
Measure the resistance at ETACS-ECU connector C-301

CAUTION

Disconnect the negative battery terminal. For details refer
to

P.54C-7

.

(1) Disconnect ETACS-ECU connector C-301, and check that

there is continuity at the harness side of ETACS-ECU.

(2) Check that there is continuity between ETACS-ECU

connector terminals 6 and 7.

OK: No continuity

Q: Is the check result normal?

YES : Go to Step 34.
NO : Go to Step 24.

STEP 24. Check the wiring harness between joint
connector (CAN1) C-103 and combination meter connector
C-03 for line-to-line short. Measure the resistance at joint
connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and check that there is

continuity at the harness side of joint connector (CAN1).

(2) Check that there is continuity between joint connector

(CAN1) terminals 4 and 15.

OK: No continuity

Q: Is the check result normal?

YES (vehicles with KOS) : Go to Step 25.
YES (vehicles with WCM) : Go to Step 26.
NO (vehicles with KOS or WCM) : Go to Step 44.

STEP 25. Check the wiring harness between joint
connector (CAN1) C-103 and KOS-ECU connector C-102
for line-to-line short. Measure the resistance at joint
connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and check that there is

continuity at the harness side of joint connector (CAN1).

(2) Check that there is continuity between joint connector

(CAN1) terminals 8 and 21.

OK: No continuity

Q: Is the check result normal?

YES : Go to Step 27.
NO : Go to Step 45.

STEP 26. Check the wiring harness between joint
connector (CAN1) C-103 and WCM connector C-29 for
line-to-line short. Measure the resistance at joint
connector (CAN1) C-103.
(1) Disconnect joint connector (CAN1), and check that there is

continuity at the harness side of joint connector (CAN1).

(2) Check that there is continuity between joint connector

(CAN1) terminals 5 and 16.
