STEP 6. Check the harness wire between ignition switch
(IG1) and ETACS-ECU connector D-11.

NOTE: After inspecting junction block connector D-08 inspect
the wires. If junction block connector D-08 is damaged, repair
or replace it. Refer to GROUP 00E

P.00E-2

, Harness Connec-

tor Inspection. Then go to Step 21.
Q: Are the harness wire damaged?

YES : Repair or replace the harness wire, then go to Step

21.

NO : Replace the ETACS-ECU and then go to Step 21.

STEP 7. Check power window relay connector C-75X for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is the connector in good condition?

YES : Go to Step 8.
NO : Repair or replace the damaged components. Refer to

GROUP 00E

P.00E-2

, Harness Connector inspection.

Then go to Step 21.

STEP 8. Measure the power window relay continuity.
(1) Remove the power window relay (Refer to

P.42-137

).

(2) Follow the table to check the power window relay continuity.

Q: Does the measured resistance value correspond with

this range?
YES : Go to Step 9.
NO : Replace power window relay, then go to Step 21.

STEP 9. Measure the power window relay supply circuit
[ETACS-ECU] at the power window relay connector C-75X.
(1) Remove the power window relay, and measure at the power

window relay connector C-75X (relay box side).

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 4 and ground.
Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 12.
NO : Go to Step 10.

, Harness Connector inspection.

Then go to Step 21.

STEP 11. Check the harness wire between ETACS-ECU
connector D-26 (terminal No.26) and power window relay
connector C-75X (terminal No.4).
Q: Are the harness wire damaged?

YES : Repair or replace the harness wire, then go to Step

21.

NO : Replace the ETACS-ECU and then go to Step 21.

STEP 12. Measure the power window relay supply circuit
at power window relay connector C-75X.
(1) Remove the power window relay, and measure at power

window relay connector C-75X (relay box side).

(2) Measure the resistance between terminal 2 and ground.
Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 14.
NO : Go to Step 13.

STEP 13. Check the harness wire between power window
relay connector C-75X (terminal No.2) and ground.
Q: Is the harness wire damaged?
