STEP 4. Check the wiring harness between B-107
TC-SST-ECU connector terminal No. 19 and body ground.
Check the ground line for open circuit.
Q: Is the check result normal?
YES : Go to Step 5.
NO : Repair the wiring harness.
STEP 5. Measure the voltage at B-107 TC-SST-ECU
connector.
Disconnect the connector, and measure the voltage between
terminal No. 6 and ground at the wiring harness side.
OK: Battery positive voltage
Q: Is the check result normal?
YES : Go to Step 8.
NO : Go to Step 6.
STEP 6. Inspection of the intermediate connector and
TC-SST-ECU connector: A-13, B-107
Check for the contact with terminals.
Q: Is the check result normal?
YES : Go to Step 7.
NO : Repair the defective connector.
STEP 7. Check the wiring harness between B-107

36.
Check the power supply line for short or open circuit.
Q: Is the check result normal?
YES : Go to Step 8.
NO : Repair the wiring harness.

54A
− Troubleshooting
P.54A-582
.)
Q: Is the DTC set?
YES : Perform the relevant troubleshooting.
NO : Go to Step 9.
STEP 9. Measure the voltage at B-107 TC-SST-ECU
connector.
(1) Disconnect the connector, and measure the voltage
between terminal No. 11 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 12.
