Pinpoint Test E: The Roof Opening Panel Does Not Open or Close

Refer to Wiring Diagram Set 101, Roof Opening Panel for schematic and connector information Electrical Diagrams.

NOTE: The roof opening panel motor must be initialized when repairs are carried out on any part of the roof opening panel system, including:
- whenever the roof opening panel motor has been removed from the roof opening panel system.
- whenever the roof opening panel glass has been removed from the roof opening panel system.
- whenever the roof opening panel assembly has been removed from the vehicle.
- whenever a new roof opening panel motor has been installed.
- whenever a new roof opening panel glass has been installed.
- whenever a new roof opening panel assembly has been installed.
Refer to Roof Opening Panel Motor Initialization Programming and Relearning.

Normal Operation

The roof opening panel uses an integrated motor and module to operate the roof opening panel. A new roof opening panel module is installed as an assembly.

The roof opening panel module receives voltage from the Central Junction Box (CJB) when the ignition is ON. The roof opening panel switch receives voltage from the roof opening panel module and then supplies voltage signals back to the roof opening panel module to operate the roof opening panel, depending on switch position.

This pinpoint test is intended to diagnose the following:

- Fuse(s)

- Wiring, terminals or connectors

- Roof opening panel switch

- Roof opening panel module

PINPOINT TEST E : THE ROOF OPENING PANEL DOES NOT OPEN OR CLOSE

E1 CHECK THE ROOF OPENING PANEL SWITCH

- Ignition OFF.

- Disconnect: Roof Opening Panel Switch C912.

- Carry out the roof opening panel switch component test.

Is the roof opening panel switch OK?

Yes
GO to E2.

No
INSTALL a new roof opening panel switch. TEST the system for normal operation.

E2 CHECK THE ROOF OPENING PANEL MODULE GROUND CIRCUIT FOR AN OPEN

- Disconnect: Roof Opening Panel Module C921.

- Measure the resistance between roof opening panel module C921-1, circuit GD145 (BK/BU), harness side and ground.





Is the resistance less than 5 ohms?

Yes
GO to E3.

No
REPAIR the circuit. TEST the system for normal operation.

E3 CHECK VOLTAGE TO THE ROOF OPENING PANEL MODULE

- Ignition ON.

- Measure the voltage between ground and
- roof opening panel module C921-3, circuit CBP08 (GY/YE)

- roof opening panel module C921-6, circuit SBP35 (BU/RD)






Are the voltages greater than 10 volts?

Yes
GO to E4.

No
VERIFY CJB (Central Junction Box) fuses 8 (7.5A) and 35 (20A) are OK. If OK, REPAIR the affected circuit(s). TEST the system for normal operation.

If not OK, REFER to the Wiring Diagrams to identify the possible causes of the circuit short Electrical Diagrams. TEST the system for normal operation.

E4 CHECK VOLTAGE TO THE ROOF OPENING PANEL SWITCH

- Ignition OFF.

- Connect: Roof Opening Panel Module C921.

- Ignition ON.

- Measure the voltage between roof opening panel switch C912-1, circuit CPR39 (VT/WH), harness side and ground.





Is the voltage greater than 10 volts?

Yes
GO to E5.

No
GO to E8.

E5 CHECK THE ROOF OPENING PANEL TILT UP CIRCUIT FOR AN OPEN

- Measure the resistance between roof opening panel switch C912-3, circuit CPR38 (WH/BU), and roof opening panel module C921-4, circuit CPR38 (WH/BU) harness side.





Is the resistance less than 5 ohms?

Yes
GO to E6.

No
REPAIR the circuit. TEST the system for normal operation.

E6 CHECK THE ROOF OPENING PANEL CLOSE/DOWN CIRCUIT FOR AN OPEN

- Measure the resistance between roof opening panel module C921-10, circuit CPR40 (YE/OG), harness side and:
- roof opening panel switch C912-2, circuit CPR40 (YE/OG), harness side.

- roof opening panel switch C912-5, circuit CPR40 (YE/OG), harness side.






Is the resistance less than 5 ohms?

Yes
GO to E7.

No
REPAIR the affected circuit(s). TEST the system for normal operation.

E7 CHECK THE ROOF OPENING PANEL OPEN CIRCUIT FOR AN OPEN

- Measure the resistance between roof opening panel switch C912-4, circuit CPR31 (VT/BN), and roof opening panel module C921-5, circuit CPR31 (VT/BN), harness side.





Is the resistance less than 5 ohms?

Yes
GO to E9.

No
REPAIR the circuit. TEST the system for normal operation.

E8 CHECK THE ROOF OPENING PANEL SWITCH VOLTAGE CIRCUIT FOR AN OPEN

- Measure the resistance between roof opening panel switch C912-1, circuit CPR39 (VT/WH), and roof opening panel module C921-2, circuit CPR39 (VT/WH), harness side.





Is the resistance less than 5 ohms?

Yes
GO to E9.

No
REPAIR the circuit. TEST the system for normal operation.

E9 CHECK THE ROOF OPENING PANEL MODULE FOR CORRECT OPERATION

- Inspect the roof opening panel module electrical connector.

- Check for:
- corrosion.

- bent pins.

- pushed-out pins.


- Connect the roof opening panel module connector and make sure it seats correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new roof opening panel module. REFER to Roof Opening Panel Motor Roof Opening Panel Motor. TEST the system for normal operation.

No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
