STEP 8. Check the ground circuit to the sunroof motor (1) Disconnect sunroof motor assembly connector D-04 and ZC500788 Connector D-04 0001 (2) Measure the resistance value between terminal 2 and ⦆ The resistance should be 2 ohms or less. Q:Is the measured resistance 2 ohms or less? YES: Go to Step 10. NO: Go to Step 9. STEP 9. Check the wiring harness between sunroof motor Q:Is the wiring harness between sunroof motor assembly connector D-04 (terminal 2) and ground in good condition? YES: No action is necessary and testing is complete. NO: The wiring harness may be damaged or the connector (s) may have loose, corroded or damaged terminals, or STEP 10. Check the fusible link (34) line of power supply (1) Disconnect sunroof motor assembly connector D-04 and ZC500795 Connector D-04 0000 (2) Measure the voltage between terminal 6 and ground. ⦆ The voltage should measure approximately 12 volts Q:Is the measured voltage approximately 12 volts (battery positive voltage)? YES: Go to Step 12. NO: Go to Step 11. STEP 11. Check the wiring harness between sunroof motor NOTE: Also check ETACS-ECU connectors C-309 and C-316 for loose, corroded, or damaged terminals, or terminals pushed SUNROOF 42Ad-19 SUNROOF DIAGNOSIS |
