PINPOINT TEST B : The Roof Opening Panel Does Not Open or Close - Sliding Glass Panel
- B1 CHECK THE POWER WINDOW OPERATION
- Ignition ON.
- Verify the power windows operate.
Do the power windows operate?
Yes GO to B2. No Go to Pinpoint Test G or Go to Pinpoint Test K . - B2 CHECK THE FRONT SLIDING GLASS PANEL MOTOR FOR INITIALIZATION
- Carry out the front sliding glass panel motor initialization procedure. Refer to Roof Opening Panel Motor Initialization - Sliding Glass Panel .
Is the concern still present?
Yes GO to B3. No The system is operating normally at this time. The front sliding glass panel motor was not initialized. - B3 CHECK THE ROOF OPENING PANEL CONTROL SWITCH
- Ignition OFF.
- Disconnect: Roof Opening Panel Control Switch.
- Carry out the Roof Opening Panel Control Switch Component Test. Refer to OEM WIRING DIAGRAMS COMPONENT TESTING for component testing.
Is the roof opening panel switch OK?
Yes GO to B4. No INSTALL a new roof opening panel switch. Refer to Roof Opening Panel Control Switch . - B4 CHECK FOR VOLTAGE TO THE FRONT SLIDING GLASS PANEL MODULE
- Disconnect Roof Opening Panel Module.
- Ignition ON.
Are the voltages greater than 11 volts?
Yes GO to B5. No VERIFY BJB fuse 8 (20A) and BCM fuse 38 (10A) are OK. If OK, REPAIR the affected circuit(s). If not OK, REFER to the SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. - B5 CHECK THE FRONT SLIDING GLASS PANEL MODULE GROUND
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead C921-4 Ground
Is the resistance less than 3 ohms?
Yes GO to B6. No REPAIR the circuit. - B6 CHECK THE SLIDING GLASS CONTROL CIRCUITS FOR AN OPEN
- Measure:
Positive Lead Measurement / Action Negative Lead C921-5 C912A-6 C921-6 C912A-8 C921-12 C912A-12
Are the resistances less than 3 ohms?
Yes CHECK the overhead console jumper harness for loose pins or an open in the affected circuit(s) between the glass smartmotor and overhead console C921. If the overhead console jumper harness is not OK, INSTALL a new overhead console jumper harness. If the overhead console jumper harness is OK, GO to B7. No REPAIR the affected circuit(s). - Measure:
- B7 CHECK THE SLIDING GLASS CONTROL CIRCUITS FOR A SHORT TO GROUND
- Measure:
Positive Lead Measurement / Action Negative Lead C921-5 Ground C921-6 Ground C921-12 Ground
Are the resistances greater than 10, 000 ohms?
Yes CHECK the overhead console jumper harness for loose pins or an open in the affected circuit(s) between the glass smartmotor and overhead console C921. If the overhead console jumper harness is not OK, INSTALL a new overhead console jumper harness. If the overhead console jumper harness is OK, GO to B8. No REPAIR the affected circuit(s). - Measure:
- B8 CHECK THE ROOF OPENING PANEL MODULE FOR CORRECT OPERATION
- Ignition OFF.
- Disconnect and inspect the roof opening panel module connector.
- 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
- Reconnect the roof opening panel module connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSBs address this concern, INSTALL a new front sliding glass panel module. Refer to Roof Opening Panel Motor - Sliding Front Panel . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
