1. Apply battery positive voltage and connect the ground to roof motor terminals A and E, and then inspect the roof motor operation.
If the roof motor does not operate as indicated in the table, replace it.
If the roof motor temperature is high, the motor may not rotate due to the motor internal PTC function. Leave it untouched for about 3 min to cool it down, then reinspect.
2. Connect the battery positive voltage to roof motor terminal B and connect terminal F to ground.
3. Operate the roof motor and measure the voltage at terminal D.
If there is any malfunction, replace the roof motor.
