Pinpoint Test E: The Roof Opening Panel Does Not Open Or Close - Sliding Glass Panel Or Shades Inoperative

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Both the power sliding glass motor and the power shade motor must be the same build level. For information on the build level of the motor, refer to the REMOVAL AND INSTALLATION of that motor.

NOTE: The jumper wiring harness is different on the older level (black and silver) and the newer level (blue and white) motors. They are not interchangeable. Make sure to match the jumper wiring harness with the correct level of motor.

- Yes: GO to E4 .
- No: INSTALL a new roof opening panel switch. REFER to ROOF OPENING PANEL CONTROL SWITCH . TEST the system for normal operation.
E4 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR ASSEMBLY - CIRCUITS CBP41 (BU) AND SBB18 (YE/RD)
- Disconnect: Roof Opening Panel Motor Assembly C920.
- Ignition ON.
- Measure the voltage between roof opening panel motor assembly C920-13, circuit CBP41 (BU), harness side and ground; and between C920-1, circuit SBB18 (YE/RD), harness side and ground.

- Are the voltages greater than 10 volts?
- Yes: GO to E5 .
- No: VERIFY Smart Junction Box (SJB) fuse 41 (15A) and Battery Junction Box (BJB) fuse 18 (20A) are OK. If OK, REPAIR the circuit. TEST the system for normal operation.
  If not OK, REFER to the SYSTEM WIRING DIAGRAMS for Edge or SYSTEM WIRING DIAGRAMS for MKX to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation.
E5 CHECK THE ROOF OPENING PANEL MOTOR ASSEMBLY GROUND - CIRCUIT GD133 (BK)
- Ignition OFF.
- Measure the resistance between roof opening panel motor assembly C920-8, circuit GD133 (BK), harness side and ground.

- 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 SWITCH GROUND - CIRCUIT GD133 (BK) FOR AN OPEN
- Measure the resistance between roof opening panel switch C9001-2, circuit GD133 (BK), harness side and ground.

- Is the resistance less than 5 ohms?
- Yes: GO to E7 .
- No: REPAIR the circuit. TEST the system for normal operation.

E7 CHECK CIRCUITS CPR31 (VT/BN), CPR38 (WH/BU) AND CPR40 (YE/OG) FOR A SHORT TO GROUND

Using the following table, measure the resistance between roof opening panel motor assembly C920, harness side and ground:

Is the roof opening panel motor wiring harness OK?

Yes: GO to E10 .
No: INSTALL a new roof opening panel motor wiring harness. REFER to ROOF OPENING PANEL MOTOR WIRING HARNESS . INITIALIZE the roof opening panel motor. REFER to ROOF OPENING PANEL MOTOR INITIALIZATION . TEST the system for normal operation.

E10 CHECK THE ROOF OPENING PANEL MOTOR ASSEMBLY FOR CORRECT OPERATION
- Disconnect all roof opening panel motor connectors (sliding glass motor and shade motor).
- Check for:
  - corrosion.
  - bent or pushed-out pins.
- Connect all roof opening panel motor connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes: INSTALL a new roof opening sliding glass panel motor. REFER to ROOF OPENING PANEL MOTOR - SLIDING FRONT PANEL . INITIALIZE the roof opening panel motor. REFER to ROOF OPENING PANEL MOTOR INITIALIZATION . TEST the system for normal operation. If the concern is still present and both motors and harness were not replaced during the Roof Opening Panel Motor - Sliding Front Panel procedure, INSTALL a new roof opening panel shade motor. REFER to ROOF OPENING PANEL MOTOR - SHADE . INITIALIZE the roof opening panel motor. REFER to ROOF OPENING PANEL MOTOR INITIALIZATION . 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.
