How To Proceed With Troubleshooting

HINT

• Use these procedures to troubleshoot the sliding roof system
• * Use the intelligent tester or Techstream

1. VEHICLE BROUGHT TO WORKSHOP 
2. INSPECT BATTERY VOLTAGE 

   Standard voltage: 11 to 14 V 

   If the voltage is below 11 V, recharge or replace the battery before proceeding.

3. INSPECT COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM* 
   1. Using the intelligent tester or Techstream, check if the CAN communication system is functioning normally.
