Pinpoint Test

1. Attempt to open and close the front sliding glass panel using the roof opening panel control switch.

Does the front sliding glass panel open and close using the slide control switch? 

1. Yes: GO to 2  .
2. No: REFER to Diagnostic Routine B: The Roof Opening Panel Does Not Open or Close - Sliding Glass Panel .

1. Ignition OFF.
2. Disconnect: Roof Opening Panel Control Switch.
3. Carry out the Roof Opening Panel Control Switch Component Test.

   Refer to ROOF OPENING PANEL CONTROL SWITCH - COMPONENT TESTING for schematic and connector information.

Is the roof opening panel switch OK? 

1. Yes: GO to 3  .
2. No: INSTALL a new roof opening panel switch. REFER to Roof Opening Panel Control Switch .

1. Disconnect Roof Opening Panel Module electrical connector.
2. Measure:

   Roof Opening Panel Module			Roof Opening Panel Control Switch
   C921			C912
   Pin	Circuit	Measurement / Action	Pin	Circuit
   7	CPR38 (WH/BU)		3	CPR38 (WH/BU)

Is the resistance less than 3 ohms? 

1. Yes: CHECK the overhead console jumper harness for loose pins or an open in circuit CPR38 (WH/BU) between the roof opening panel switch socket and overhead console C921-7. 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 4  .
2. No: REPAIR the circuit.

1. Ignition OFF.
2. Disconnect and inspect the roof opening panel module connector.
3. 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
4. Reconnect the roof opening panel module connector. Make sure it seats and latches correctly.
5. Operate the system and determine if the concern is still present.

Is the concern still present? 

1. 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 .
2. 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.
