WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

E1 CHECK THE MOTOR/MODULE FOR INITIALIZATION
- Carry out the roof opening panel motor initialization procedure. Refer to ROOF OPENING PANEL MOTOR INITIALIZATION .
- Is the concern still present?
Yes : GO to E2.

No : The system is operating normally at this time. The roof opening panel motor was not initialized.
E2 CHECK THE POWER WINDOWS
- Key in ON position.
- Verify the power windows operate.
- Do the power windows operate?
Yes : GO to E3.

No : REFER to GLASS, FRAMES AND MECHANISMS to diagnose the accessory delay relay circuit.
E3 CHECK THE ROOF OPENING PANEL SWITCH
- Key in OFF position.
- Disconnect: Roof Opening Panel Switch C912.
- Carry out the roof opening panel switch component test. Refer to COMPONENT TESTING .
- Is the roof opening panel switch OK?
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/MODULE - CIRCUIT CBP02 (GN) AND SBB33 (RD)
- Key in OFF position.
- Disconnect: Roof Opening Panel Motor/Module C921.
- Key in ON position.
- Measure the voltage between roof opening panel motor/module C921-2, circuit CBP02 (GN) and C921-1, circuit SBB33 (RD), harness side and ground.

- Are the voltages greater than 10 volts, but less than 16 volts?
Yes : GO to E5.

No : VERIFY SJB fuse 12 (7.5A) and BJB fuse 33 (20A) are OK. If OK, REPAIR the circuit. TEST the system for normal operation.
E5 CHECK THE ROOF OPENING PANEL GROUND - CIRCUIT GD139 (BK/YE)
- Key in OFF position.
- Measure the resistance between roof opening panel motor/module C921-4, circuit GD139 (BK/YE), 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 CIRCUIT CPR39 (VT/WH) FOR AN OPEN
- Measure the resistance between overhead console C912-4, circuit CPR39 (VT/WH), and roof opening panel motor/module C921-11, circuit CPR39 (VT/WH) harness side.

- Is the resistance less than 5 ohms?
Yes : CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR39 (VT/WH) between the roof opening panel switch socket and overhead console C912-4. If the overhead console jumper harness is not OK, INSTALL a new overhead console jumper harness and TEST the system for normal operation. If the overhead console jumper harness is OK, GO to E7.

No : REPAIR the circuit. TEST the system for normal operation.
E7 CHECK CIRCUIT CPR40 (YE/OG) FOR AN OPEN
- Measure the resistance between overhead console C912-7, circuit CPR40 (YE/OG), and roof opening panel motor/module C921-6, circuit CPR40 (YE/OG) harness side.

- Is the resistance less than 5 ohms?
Yes : CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR40 (YE/OG) between the roof opening panel switch socket and overhead console (J912-7. If the overhead console jumper harness is not OK, INSTALL a new overhead console jumper harness and TEST the system for normal operation. If the overhead console jumper harness is OK, GO to E8.

No : REPAIR the circuit. TEST the system for normal operation.
E8 CHECK CIRCUIT CPR31 (VT/BN) FOR AN OPEN
- Measure the resistance between overhead console C912-3, circuit CPR31 (VT/BN), and roof opening panel motor/module C921-5, circuit CPR31 (VT/BN) harness side.

- Is the resistance less than 5 ohms?
Yes : CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR31 (VT/BN) between the roof opening panel switch socket and overhead console C912-3. If the overhead console jumper harness is not OK, INSTALL a new overhead console jumper harness, and TEST the system for normal operation. If the overhead console jumper harness is OK, GO to E9.

No : REPAIR the circuit. TEST the system for normal operation.
E9 CHECK CIRCUIT CPR38 (BU/BK) FOR AN OPEN
- Measure the resistance between overhead console C912-2, circuit CPR38 (WH/BU), and roof opening panel motor/module C921-7, circuit CPR38 (WH/BU) harness side.

  Courtesy of FORD MOTOR CO.
- Is the resistance less than 5 ohms?
Yes : CHECK the overhead console jumper harness for loose pins, an open or a short in circuit CPR38 (WH/BU) between the roof opening panel switch socket and overhead console C912-2. If the overhead console jumper harness is not OK, INSTALL a new overhead console jumper harness, and TEST the system for normal operation. If the overhead console jumper harness is OK, GO to E10.

No : REPAIR the circuit. TEST the system for normal operation.
E10 CHECK THE ROOF OPENING PANEL MOTOR/MODULE FOR CORRECT OPERATION

Disconnect all roof opening panel motor/module connectors.
Check for:
- Corrosion.
- Bent or pushed-out pins.
Connect all roof opening panel motor/module 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 panel motor/module. REFER to 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.
