Diagnostic Overview

The Roof Opening Panel Does Not Open or Close

Refer to Wiring Diagram Set 101 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

REFER to Roof Opening Panel . The roof opening panel motor/module must be initialized when repairs are carried out on any part of the roof opening panel system or when a new component is installed. The motor/module uses the initialization procedure to "learn" the positions of the roof opening panel. A failure in the power or ground circuit, an internal failure of the switch or motor/module or a motor/module that has not been initialized all cause the roof opening panel to become inoperative.

Visual Inspection and Diagnostic Pre-checks

Inspect rear junction box fuse 37 (5A)

Inspect BCM (Body Control Module) fuse 80 (20A)

Pinpoint Test

1. CHECK THE ROOF OPENING PANEL MOTOR/MODULE FOR INITIALIZATION

1. Attempt to carry out the roof opening panel motor/module initialization procedure. REFER to Roof Opening Panel Motor Initialization Programming and Relearning.

2. Operate the system and determine if the concern is still present.

Is the concern still present?






2. CHECK THE OVERHEAD CONSOLE SWITCH ASSEMBLY

1. Ignition OFF.

2. Disconnect the overhead console switch assembly electrical connector.

3. Carry out the Overhead Console Switch Assembly Component Test.

Is the overhead console switch assembly OK?






3. CHECK THE BATTERY VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE

1. Disconnect the roof opening panel motor/module electrical connector.

2. Measure:





Is the voltage greater than 11 volts?






4. CHECK THE IGNITION VOLTAGE TO THE ROOF OPENING PANEL MOTOR/MODULE

1. Ignition ON.

2. Measure:





Is the voltage greater than 11 volts?






5. CHECK THE ROOF OPENING PANEL MOTOR/MODULE GROUND CIRCUIT

1. Ignition OFF.

2. Measure:





Is the resistance less than 3 ohms?






6. CHECK THE ROOF OPENING PANEL MOTOR/MODULE CLOSE CIRCUIT FOR AN OPEN

1. Measure:





Is the resistance less than 3 ohms?






7. CHECK THE ROOF OPENING PANEL MOTOR/MODULE OPEN CIRCUIT FOR AN OPEN

1. Measure:





Is the resistance less than 3 ohms?






8. CHECK THE ROOF OPENING PANEL MOTOR/MODULE FOR CORRECT OPERATION

1. Inspect the roof opening panel motor/module electrical connector.

2. Repair:

- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Connect the roof opening panel motor/module electrical connector. Make sure it seats and latches correctly.

4. Connect the overhead console switch assembly electrical connector.

5. Operate the system and determine if the concern is still present.

Is the concern still present?
