Yes
GO to A5.
No
REPAIR circuit 33-AG6 (YE). TEST the system for normal operation.
A5: CHECK FOR CONTINUITY BETWEEN THE ROOF OPENING PANEL CONTROL SWITCH AND THE ROOF OPENING PANEL MOTOR

1
Measure the resistance between the roof opening panel control switch C215 pin 7, circuit 32-AG6 (WH), harness side and the roof opening panel motor C346 pin 2, circuit 32-AG6 (WH), harness side.

Is the resistance less than 5 ohms?
Yes
INSTALL a new roof opening panel motor. TEST the system for normal operation.
No
REPAIR circuit 32-AG6 (WH). TEST the system for normal operation.
A6: CHECK FOR VOLTAGE TO THE ROOF OPENING PANEL CONTROL SWITCH
1
Ignition switch in position 0.
2
Disconnect Roof Opening Panel Control Switch C215.
3
Ignition switch in position II.

Component Test

Roof Opening Panel Control Switch

  1. Measure the resistance between the following:

Roof Opening Panel Control Switch Position Terminals Measurements
Neutral 3-7 Less than 5 ohms
Neutral 1-6 Less than 5 ohms
Neutral 2-7 Greater than 10,000 ohms
Neutral 1-2 Greater than 10,000 ohms
Up/Close 1-2 Less than 5 ohms
Up/Close 3-7 Less than 5 ohms
Up/Close 1-6 Greater than 10,000 ohms
Down/Open 1-6 Less than 5 ohms
Down/Open 2-7 Less than 5 ohms
