STEP 21. Check the wiring harness between joint
connector (CAN1) C-105 and radio and CD player or CD
changer connector C-107 for a short to power supply.
Measure the voltage at joint connector (CAN1) C-105.
(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 5 and body ground.
OK: 4.7 V or less
(4) Measure the voltage between joint connector (CAN1)
terminal 16 and body ground.
OK: 4.7 V or less
Q: Do all the voltages measure 4.7 V or less?
YES (vehicles without satellite radio) : Go to Step 24.
YES (vehicles with satellite radio) : Go to Step 23.
NO : Go to Step 55.

STEP 23. Check the wiring harness between joint
connector (CAN1) C-105 and satellite radio tuner
connector C-18 for a short to power supply. Measure the
voltage at joint connector (CAN1) C-105.
(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 2 and body ground.
OK: 4.7 V or less
(4) Measure the voltage between joint connector (CAN1)
terminal 13 and body ground.
OK: 4.7 V or less
Q: Do all the voltages measure 4.7 V or less?
YES : Go to Step 24.
NO : Go to Step 57.

STEP 24. Check the wiring harness between joint
connector (CAN1) C-105 and ETACS-ECU connector C-301
for a short to power supply. Measure the voltage at joint
connector (CAN1) C-105.
(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 V or less
(4) Measure the voltage between joint connector (CAN1)
terminal 19 and body ground.
OK: 1 V or less
Q: Do all the voltages measure 1 V or less?
YES : Go to Step 58.
NO : Repair the wiring harness between joint connector
(CAN1) C-105 and ETACS-ECU connector C-301.
STEP 25. 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
.
(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 37.
NO : Go to Step 26.
