STEP 13. Check the wiring harness between C-139
AWC-ECU connector terminal No.16 and C-313
ETACS-ECU connector terminal No.2.
Check the power supply line for short circuit.
Q: Is the check result normal?
YES : Replace the fuse No.12, No.17. Then go to Step 24.
NO : Repair the wiring harness, and then replace the fuse
STEP 14. Voltage measurement at C-309 ETACS-ECU
connector
Disconnect the connector, and measure the voltage between
terminal No.1 and ground at the wiring harness side.
OK: Battery positive voltage
Q: Is the check result normal?
YES : Go to Step 16.
NO : Go to Step 15.
STEP 15. ETACS-ECU connector check: C-309
Q: Is the check result normal?
YES : The short or open circuit may be present in the power
supply circuit. Repair the wiring harness between the
C-309 ETACS-ECU connector terminal No.1 and
fusible link No.34. Then go to Step 26.
NO : Repair the defective connector. Then go to Step 26.
STEP 16. Voltage measurement at C-317 ETACS-ECU
connector
(1) Disconnect the connector, and measure the voltage
between terminal No.6 and ground at the wiring harness
side.
(2) Turn the ignition switch to the "ON" position.
OK: Battery positive voltage
Q: Is the check result normal?
YES : Go to Step 18.
NO : Go to Step 17.
STEP 17. ETACS-ECU connector check: C-317
Q: Is the check result normal?
YES : The short or open circuit may be present in the power
supply circuit. Repair the wiring harness between the
C-317 ETACS-ECU connector terminal No.6 and
ignition switch. Then go to Step 26.
NO : Repair the defective connector. Then go to Step 26.

terminal No.12 and ground at the wiring harness side.
OK: Battery positive voltage
Q: Is the check result normal?
YES : Go to Step 20.
NO : Go to Step 19.
STEP 19. Intermediate connector, AWC-ECU connector,
ETACS-ECU connector check: C-31, C-138, C-139, C-315
Q: Is the check result normal?
YES : The open circuit may be present in the power supply
circuit. Repair the wiring harness between the C-139
AWC-ECU connector terminal No.12 and C-315
ETACS-ECU connector terminal No.4. Then go to
Step 26.
NO : Repair the defective connector. Then go to Step 26.
STEP 20. Voltage measurement at C-139 AWC-ECU
connector
(1) Disconnect the connector, and measure the voltage
between terminal No.16 and ground at the wiring harness
side.
(2) Turn the ignition switch to the "ON" position.
OK: Battery positive voltage
Q: Is the check result normal?
YES : Go to Step 22.
NO : Go to Step 21.
STEP 21. Intermediate connector, AWC-ECU connector,
ETACS-ECU connector check: C-138, C-139, C-313
Q: Is the check result normal?
YES : The open circuit may be present in the power supply
circuit. Repair the wiring harness between the C-139
AWC-ECU connector terminal No.16 and C-313
ETACS-ECU connector terminal No.2. Then go to
Step 26.
NO : Repair the defective connector. Then go to Step 26.
STEP 22. Resistance measurement at C-139 AWC-ECU
connector
Disconnect the connector, and measure the resistance
between terminal No.13 and ground at the wiring harness side.
OK: Continuity (Less than 2
Ω)
Q: Is the check result normal?
