STEP 7. Check the battery power supply circuit to the sunroof motor assembly. Test at sunroof motor assembly connector D-08 by backprobing.

1. Measure the voltage available at the harness side of sunroof motor assembly connector D-08 without disconnecting sunroof motor assembly.
2. Turn the ignition switch to ON position.
3. Measure the voltage between terminal 2 and ground by backprobing.
- The voltage should measure approximately 12 volts (battery positive voltage).

Q: Is the measured voltage approximately 12 volts (battery positive voltage)?

YES: Go to Step 10.
NO: Go to Step 8.




STEP 8. Check sunroof motor assembly connector D-08 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Is the sunroof motor assembly connector D-08 in good condition?
