| 3 Connect CJB C367. |
| 4 Ignition switch in position II. |
| 5 Measure the voltage between the roof opening panel adjust switch connector C3009 pin 2, circuit 14-AG7 (VT/BU), and ground. |
| Is the voltage greater than 10 volts? Yes No |
E6: CHECK CIRCUIT 14-AG7 (VT/BU) FOR CONTINUITY |
| 1 Ignition switch in position 0. |
| 2 Disconnect Roof opening panel unit C748b. |
| 3 Measure the resistance between the roof opening panel unit connector C748b pin 5, circuit 14-AG7 (VT/BU), and the roof opening panel adjust switch connector C3009 pin 2, circuit 14-AG7 (VT/BU). |
| Is the resistance less than 5 ohms? Yes INSTALL a new roof opening panel unit. TEST the system for normal operation. No REPAIR circuit 14-AG7 (VT/BU). TEST the system for normal operation. |
E7: CHECK CIRCUIT 31-AG7 (BK) FOR CONTINUITY |
| 1 Measure the resistance between the roof opening panel unit connector C748b pin 4, circuit 31-AG7 (BK), and the roof opening panel adjust switch connector C3009 pin 3, circuit 31-AG7 (BK). |
| Is the resistance less than 5 ohms? Yes No REPAIR circuit 31-AG7 (BK). TEST the system for normal operation. |
E8: CHECK CIRCUIT 31-AG6 (BK) FOR CONTINUITY |
| 1 Measure the resistance between the roof opening panel unit connector C748b pin 1, circuit 31-AG6 (BK), and the roof opening panel adjust switch connector C3009 pin 6, circuit 31-AG6 (BK). |
