Pinpoint Test E: the Roof Opening Panel Does Not Open Or Close

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

Result / Action to Test Step Take

E1 CHECK THE POWER WINDOWS

Yes GO to E2. No Ignition ON. REFER to Glass, Verify the power windows operate. Frames and Do the power windows operate? Mechanisms to

diagnose the accessory delay relay circuit.

E2 CHECK THE MOTOR/MODULE FOR

INITIALIZATION

Yes Attempt to carry out the Roof Opening Panel Motor GO to E3. Initialization procedure. Refer to Roof Opening Panel No Motor Initialization in this section. The system is Is the concern still present, or does the roof operating normally at opening panel motor fail to initialize? this time. The roof opening panel motor was not initialized.

E3 CHECK THE ROOF OPENING PANEL SWITCH

Ignition OFF. Yes Disconnect: Roof Opening Panel Switch C912. GO to E4. Carry out the Roof Opening Panel Switch Component No Test. INSTALL a new roof Refer to Wiring Diagrams Cell 149 for component opening panel switch. Result / Action to Test Step Take

REFER to Roof Opening Panel testing. Control Switch in this Is the roof opening panel switch OK? section. TEST the

system for normal operation.

E4 CHECK VOLTAGE TO THE ROOF OPENING

PANEL MOTOR/MODULE

Ignition OFF. Disconnect: Roof Opening Panel Motor/Module C921. Ignition ON. Yes Measure the voltage between roof opening panel GO to E5. motor/module C921-3, circuit CBP47 (GN/BU), harness No side and roof opening panel motor/module C921-6, VERIFY Smart circuit SBP01 (RD), harness side and ground. Junction Box (SJB) fuse 1 (30A) and circuit breaker 47 (30A) are OK. If OK, REPAIR the circuit. If not OK, REFER to the Wiring Diagrams manual to identify the possible causes of the circuit short. TEST the system for Is the voltage greater than 10 volts for both normal operation. measurements?

E5 CHECK THE ROOF OPENING PANEL

MOTOR/MODULE GROUND

Ignition OFF. Yes Measure the resistance between roof opening panel GO to E6. motor/module C921-1, circuit GD139 (BK/YE), harness No side and ground. REPAIR the circuit. Result / Action to Test Step Take

TEST the system for normal operation.

Is the resistance less than 5 ohms?

E6 CHECK THE ROOF OPENING PANEL CONTROL

SWITCH GROUND

Measure the resistance between roof opening panel switch C912-12, circuit CPR39 (VT/WH), harness side and ground.

Yes GO to E8. No GO to E7.

E7 CHECK COMMON FOR AN OPEN

Measure the resistance between roof opening panel Yes switch C912-12, circuit CPR39 (VT/WH), harness side INSTALL a new roof and roof opening panel motor/module C921-2, circuit opening panel CPR39 (VT/WH), harness side. motor/module. Result / Action to Test Step Take

REFER to Roof Opening Panel Motor in this section. TEST the system for normal operation. No REPAIR the circuit. TEST the system for Is the resistance less than 5 ohms? normal operation.

E8 CHECK CIRCUIT CPR40 (YE/OG) FOR AN OPEN

Measure the resistance between roof opening panel switch C912-8, circuit CPR40 (YE/OG), harness side and roof opening panel motor/module C921-10, circuit CPR40 (YE/OG), harness side.

Yes GO to E9. No REPAIR the circuit. TEST the system for normal operation.

E9 CHECK CIRCUIT CPR31 (VT/BN) FOR AN OPEN

Measure the resistance between roof opening panel Yes switch C912-6, circuit CPR31 (VT/BN), harness side GO to E10. and roof opening panel motor/module C921-5, circuit No Result / Action to Test Step Take

CPR31 (VT/BN), harness side.

REPAIR the circuit. TEST the system for normal operation.

E10 CHECK CIRCUITS CPR31 (VT/BN), CPR40 (YE/OG) AND CPR38 (WH/BU) FOR A SHORT TO GROUND

Measure the resistance between roof opening panel Yes switch C912, harness side and ground using the GO to E11. following chart: No Roof Opening Panel REPAIR the circuit(s). Circuit Switch TEST the system for normal operation. C912-6 CPR31 (VT/BN) C912-3 CPR38 (WH/BU) C912-8 CPR40 (YE/OG)

Is the resistance greater than 10,000 ohms for all measurements? Result / Action to Test Step Take

E11 CHECK THE ROOF OPENING PANEL

MOTOR/MODULE FOR CORRECT OPERATION

Yes INSTALL a new roof opening panel Disconnect all roof opening panel motor/module motor/module. connectors. REFER to Roof Check for: Opening Panel Motor corrosion. in this section. TEST bent pins. the system for normal pushed-out pins. operation. Connect all roof opening panel motor/module No connectors and make sure they seat correctly. The system is Operate the system and verify the concern is still operating correctly at present. this time. Concern Is the concern still present? may have been caused by a loose or corroded connector. TEST the system for normal operation.
