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 volts or less

terminal 13 and body ground.
OK: 4.7 volts or less
Q: Do all the voltages measure 4.7 volts 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.

(4) Measure the voltage between joint connector (CAN1)
terminal 19 and body ground.
OK: 4.7 volts or less
Q: Do all the voltages measure 4.7 volts 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
.
