1. Disconnect connector C1.
2. Using a J 39200 digital multimeter (DMM), measure the voltage at CKT 1001 (YEL) to ground.

Is the voltage within the specified range?

9-16 V

Go to Step 3

Go to Step 4

Measure the voltage between CKT 1001 (YEL) and CKT 1850 (BLK).

Is the voltage within the specified range?

9-16 V

Go to Step 6

Go to Step 5

Repair the open in CKT 1001 (YEL) between the sunroof module and the body relay block.

1. Reconnect connector C1.
2. Disconnect connector C2 at the sunroof module.
3. Measure the continuity from cavity 2 (BRN) and cavity 3 (DK BLU) while depressing the switch in the OPEN position.

Is the resistance equal to or less than the specified value?

1 ohms

Go to Step 7

Go to Step 8

Measure the continuity from cavity 3 (DK BLU) and cavity 5 (ORN) while depressing the switch in the CLOSE position.

Is the resistance equal to or less than the specified value?

1 ohms

Go to Step 11

Go to Step 9

Inspect for an open from the sunroof switch and cavity 2 (BRN) and cavity 3 (DK BLU). Repair as necessary.
