Pinpoint Test B: Roof Opening Panel - Inoperative

B1: INOPERATIVE

NOTE: These tests are to be carried out to determine the cause of the loss of roof opening panel functionality

Perform the manual roof opening panel initialization procedure REFER to: Power Roof Opening Panel Initialization . Check for correct roof opening panel operation

Does the roof opening panel operate correctly?

Yes:

No further action required

No:

GO to B2 .

B2: FUSE

NOTE: These tests are to be carried out to determine the cause of the loss of roof opening panel functionality

Refer to the electrical circuit diagrams and check the fused link to the roof opening panel motor

Is the fused link (VBATT) circuit to the roof opening panel motor intact?

Yes:

GO to B3.

No:

The fused link to the roof opening panel motor has failed. Refer to the electrical circuit diagrams and check the circuit - VBATT - between the fused link and the roof opening panel motor for short circuit to ground. Replace the fused link or repair the circuit as required. Perform the manual roof opening panel initialization procedure REFER to: Power Roof Opening Panel Initialization . Check for correct operation, If correct no further action required

B3: SWITCH CONNECTOR

Access to the connector for the front overhead console REFER to: INSTRUMENT PANEL AND CONSOLE
Refer to the electrical circuit diagrams and check the roof opening panel switch terminals and housing for location and condition

Are the roof opening panel switch terminals and housing located correctly and in good condition?

Yes:

GO to B4 .

No:

Correctly relocate or replace any roof opening panel switch connector terminals as required. Perform the manual roof opening panel initialization procedure REFER to: Power Roof Opening Panel Initialization . Check for correct operation, If correct no further action required

B5: SWITCH - CIRCUIT CHECK

NOTE: The roof opening panel motor gives a voltage out on the open and close circuits which is grounded when the switch is operated, this voltage should be greater than 7volts (switch inactive) and less than 1volt (switch active) with the ignition state switched to on

Refer to the electrical circuit diagrams and locate the open and close circuits between the roof opening panel motor and the roof opening panel switch, monitor the voltage on each circuit as the switch is operated

Do both open and close switch circuit voltages change from greater than 7 volts to less than 1 volt when the roof opening panel open or close switches are pressed?

Yes:

GO to B8 .

No:

GO to B6 .

B6: SWITCH - CIRCUIT CHECK 2

NOTE: During the previous check, if the voltage remained high (greater than 7 volts) , refer to the electrical circuit diagrams and check the switch circuit for fault

NOTE: During the previous check, if the voltage remained low (less than 1 volt) , refer to the electrical circuit diagrams and check the roof opening panel motor circuit for fault

Refer to notes above

Did the voltage remain low (less than 1 volt) ?

Yes:

GO to B7 .

No:

The voltage remained high (greater than 7 volts) refer to the electrical circuit diagrams and check the roof opening panel switch circuit for fault. Repair as required. Perform the manual roof opening panel initialization procedure REFER to: Power Roof Opening Panel Initialization . Check for correct operation, If correct no further action required

B8: MOTOR - FAILURE

Uninstall the motor from the roof opening panel REFER to: Roof Opening Panel Motor .
Operate the roof opening panel using the roof mounted switch

When operating the switch, does the motor operate?

Yes:

GO to B9 .

No:

Replace the roof opening panel motor REFER to: Roof Opening Panel Motor . Check for correct operation, If correct no further action required

B9: MANUAL - ROOF OPERATION

Reinstall the roof opening panel motor to the roof opening panel frame REFER to: Roof Opening Panel Motor .
Using a large flathead screwdriver applied to the motor, operate the roof opening panel through all possible positions (slide open / slide close / tilt open / tilt close)

Can the roof opening panel be manually operated through all possible positions?

Yes:

Install a new roof opening panel module REFER to: Roof Opening Panel Module . Check for correct operation, If correct no further action required

No:

GO to B10 .

B10: GLASS PANEL - REMOVAL

Remove the glass panel from the roof opening panel REFER to: Roof Opening Panel Glass

Can the glass panel be removed?

Yes:

GO to B11 .

No:

Contact dealer technical support

B11: GLASS PANEL REMOVED

Carry out visual and manual inspection of the rail(s) for debris

Are the rail(s) free from debris?

Yes:

GO to B12 .

No:

Clear any obstructions from the rails. Apply grease (KP 1N-30 or ISO-L-X-CDBE1) to the areas shown. Then, GO to B12 .

B12: LIFTER ARMS - CONDITION

Carry out visual inspection of the lifter arms for cracks or damage (pieces broken)

Are the lifter arms cracked or damaged?

Yes:

Replace the lifter arms. Perform the manual roof opening panel initialization procedure REFER to: Power Roof Opening Panel Initialization . Check for correct operation, If correct no further action required

No:

GO to B13 .

B13: REAR MECHANISM - CONDITION

Carry out visual inspection of the rear mechanism

Are the rear mechanisms free from cracking and damage?

Yes:

GO to B14 .

No:

Install a new roof opening panel REFER to: Roof Opening Panel . Check for correct operation, If correct no further action required

B14: GLASS PANEL - RE-ASSEMBLY

Re-assemble the glass panel onto the roof opening panel REFER to: Roof Opening Panel Glass .
Perform the manual roof opening panel initialization procedure REFER to: Power Roof Opening Panel Initialization .
Check for correct roof opening panel operation

Does the roof opening panel operate correctly?

Yes:

No further action required

No:
