connector terminal No.2 and body earth.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-30 and E-29, and
repair if necessary.
- Check the earth wires for open circuit.
Q: Is the check result normal?
YES:
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope
with Intermittent Malfunction 
).NO: Repair the wiring harness.
Step 5. Measure the voltage at the E-05 power window main switch connector.
- Disconnect the connector, and measure at the wiring harness side.
- Turn the ignition switch to the ON position.
- Voltage between terminal 6 and body earth
OK: Battery positive voltage
Q: Is the check result normal?
YES:
Go to Step 8
.NO: Go to Step 6
.Step 7. Check the wiring harness between C-208 power window relay
connector terminal No.4 and E-05 power window main switch connector terminal No.6.
NOTE: Prior to the wiring harness inspection, check intermediate connectors C-30, E-29 and junction
block connector C-203, and repair if necessary.
- Check the power supply line for open circuit.
Q: Is the check result normal?
YES:
The trouble can be an intermittent malfunction (Refer to GROUP 00, How to Cope
with Intermittent Malfunction ).NO: Repair the wiring harness.
Step 9. Check the wiring harness from E-23 power window motor (front
RH) connector terminal Nos. 1 and 3 to E-05 power window main switch connector terminal Nos.
7 and 1.
NOTE: Prior to the wiring harness inspection, check intermediate connector E-29, and repair
if necessary.
- Check the input and output lines for open or short circuit.
Q: Is the check result normal?
YES:
Go to Step 10.NO: Repair the wiring harness.
Step 10. Retest the system.
- Replace the power window main switch.
- Check that the driver's power window works by means of the power window main switch.
Q: Is the check result normal?
YES:
The trouble can be an intermittent malfunction (Refer to GROUP 00 -
How
to Cope with Intermittent Malfunction ).NO: Replace the power window motor assembly (front RH).
