TECHNICAL DESCRIPTION (COMMENT)
The power window sub-switch or the power window motor (RH) may be defective. Alternatively, the power window lock switch (incorporated in the power window main switch) may remain pressed to "LOCK" position.

TROUBLESHOOTING HINTS
- Malfunction of power window main switch
- Malfunction of power window sub-switch
- Malfunction of power window motor (RH)
- Damaged harness wires or connectors

DIAGNOSIS

Required Special Tool:

STEP 1. Check the continuity of the power window main switch.

1. Remove the power window main switch. Refer to Door - Door Trim and Waterproof Film.










2. Check continuity when the switch on the power window main switch is operated to "UP" or "DOWN" position.

Q: Is the power window main switch in good condition?

YES: Go to Step 2.

NO: Replace the power window main switch. When the power window sub-switch is operated, the power window (RH) should open or close normally.

STEP 2. Check the power window lock switch.

Q: Is the power window lock switch at the "UNLOCK" position?

YES: Go to Step 3.

NO: Operate the power window lock switch to the "UNLOCK" position? When the power window sub-switch is operated, the power window (RH) should open or close normally.

STEP 3. Check the continuity of the power window sub-switch.

1. Remove the power window sub-switch. Refer to Door - Door Trim and Waterproof Film.







2. Check continuity when the power window sub-switch is operated to "UP" or "DOWN" position.

Q: Is the power window sub-switch in good condition?

YES: Go to Step 4.

NO: Replace the power window sub switch. When the power window sub-switch is operated, the power window (RH) should open or close normally.

STEP 4. Check the front power window motor (RH).

1. Remove the front power regulator assembly (RH). Refer to Door - Door Glass and Regulator.







2. Follow the given table to check the front power window motor (RH) for correct operation.

Q: Is the power window motor (RH) in good condition?

YES: Go to Step 5.

NO: Replace the front power regulator assembly (RH). When the power window sub-switch is operated, the power window (RH) should open or close normally.

STEP 5. Check at front power window sub-switch connector E-05 in order to check the power window relay circuit of the power supply to the power window sub-switch.




1. Disconnect power window sub-switch connector E-05, and measure at the harness side.




2. Measure the voltage between terminal 7 and ground.
- The measured value should be approximately 12 volts (battery positive voltage).

Q: Does the measured voltage correspond with this range?

YES: Go to Step 8.

NO: Go to Step 6.







STEP 6. Check power window relay connector C-116 and front power window sub-switch connector E-05 for damage.

Q: Are power window relay connector C-116 and power window sub-switch connector E-05 in good condition?

YES: Go to Step 7.

NO: Repair or replace the connector. Refer to Harness Connector Inspection. When the power window sub-switch is operated, the power window (RH) should open or close normally.










STEP 7. Check the wiring harness between power window relay connector C-116 (terminal 4) and power window sub switch connector E-05 (terminal 7).

NOTE: Also check junction block connector C-111 and intermediate connector C-95. If junction block connector C-111 or intermediate connectors C-95 is damaged, repair or replace the connector as described in Harness Connector Inspection.

Q: Is the wiring harness between power window relay connector C-116 (terminal 4) and power window sub switch connector E-05 (terminal 7) in good condition?

YES: No action to be taken.

NO: Repair the wiring harness. When the power window sub-switch is operated, the power window (RH) should open or close normally.

STEP 8. Measure at power window sub switch connector E-05 in order to check the ground circuit to the power window sub switch.




1. Disconnect power window sub-switch connector E-05, and measure at the harness side.




2. Measure the resistance value between terminal 8 and ground.
- The measured value should be 2 ohm or less.

Q: Does the measured resistance value correspond with this range?

YES: Go to Step 11.

NO: Go to Step 9.







STEP 9. Check power window main switch connector E-12 and front power window sub-switch (RH) connector E-05 for damage.

Q: Are power window main switch connector E-12 and power window sub-switch connector E-05 in good condition?

YES: Go to Step 10.

NO: Repair or replace the connector. Refer to Harness Connector Inspection. When the power window sub-switch is operated, the power window (RH) should open or close normally.













STEP 10. Check the wiring harness between power window main switch connector E-12 (terminal 7) and power window sub-switch connector E-05 (terminal 8).

NOTE: Also check intermediate connectors C-91 and C-95. If intermediate connectors C-91 or C-95 is damaged, repair or replace the connector as described in Harness Connector Inspection.

Q: Is the wiring harness between power window main switch connector E-12 (terminal 7) and power sub-switch connector E-05 (terminal 8) in good condition?

YES: Replace the power window main switch. When the power window sub-switch is operated, the power window (RH) should open or close normally.

NO: Repair the wiring harness. When the power window sub-switch is operated, the power window (RH) should open or close normally.

STEP 11. Measure at power window sub switch connector E-05 in order to check the ground circuit to the power window sub switch.




1. Disconnect power window sub-switch connector E-05, and measure at the harness side.




2. Measure the resistance value between terminal 5 and ground.
- The measured value should be 2 ohm or less.

Q: Does the measured resistance value correspond with this range?

YES: Go to Step 14.

NO: Go to Step 12.







STEP 12. Check power window main switch connector E-12 and front power window sub-switch (RH) connector E-05 for damage.

Q: Are power window main switch connector E-12 and power window sub-switch connector E-05 in good condition?

YES: Go to Step 13.

NO: Repair or replace the connector. Refer to Harness Connector Inspection. When the power window sub-switch is operated, the power window (RH) should open or close normally.













STEP 13. Check the wiring harness between power window main switch connector E-12 (terminal 8) and power window sub-switch connector E-05 (terminal 5).

NOTE: Also check intermediate connectors C-91 and C-95. If intermediate connectors C-91 or C-95 is damaged, repair or replace the connector as described in Harness Connector Inspection.

Q: Is the wiring harness between power window main switch connector E-12 (terminal 8) and power sub-switch connector E-05 (terminal 5) in good condition?
