- Is the voltage greater than 10 volts?
- E4 CHECK CIRCUIT (OG) FOR AN OPEN
- Key in OFF position.
- Disconnect: Roof Opening Panel Module Connector
- Measure the resistance between the roof opening panel motor connector, pin 3, circuit (OG), harness side and the roof opening panel module connector, pin 8, circuit (OG), harness side.
- Is the resistance less than 5 ohms?
- YES : Go to E5.
- NO : REPAIR the circuit. TEST the system for normal operation.
- E5 CHECK CIRCUIT (OG) FOR A SHORT TO GROUND
- Measure the resistance between the roof opening panel motor connector, pin 3, circuit (OG), harness side and ground.
- Is the resistance greater than 10,000 ohms?
- YES : Go to E9.
- NO : REPAIR the circuit. TEST the system for normal operation.
- E6 CHECK VOLTAGE TO THE ROOF OPENING PANEL MOTOR - CIRCUIT (RD)
- While pressing the roof opening panel switch to the CLOSED position, measure the voltage between the roof opening panel motor connector, pin 1, circuit (RD), harness side and ground.
- Is the voltage greater than 10 volts?
- YES : INSTALL a new roof opening panel motor. REFER to Roof Opening Panel Motor . TEST the system for normal operation.
- NO : Go to E7.
- E7 CHECK CIRCUIT (RD) FOR AN OPEN
- Key in OFF position.
- Disconnect: Roof Opening Panel Module Connector
- Measure the resistance between the roof opening panel module connector, pin 7, circuit (RD), harness side and the roof opening panel motor connector, pin 1, circuit (RD), harness side.
- Is the resistance less than 5 ohms?
- YES : Go to E8.
- NO : REPAIR the circuit. TEST the system for normal operation.
- E8 CHECK CIRCUIT (RD) FOR A SHORT TO GROUND
- Measure the resistance between the roof opening panel motor connector, pin 1, circuit (RD), harness side and ground.
- Is the resistance greater than 10,000 ohms?
- YES : Go to E9.
- NO : REPAIR the circuit. TEST the system for normal operation.
- E9 CHECK THE ROOF OPENING PANEL SWITCH
- Disconnect: Roof Opening Panel Switch Connector
- Carry out the roof opening panel control switch component test. Refer to appropriate COMPONENT TESTING article.
- Did the roof opening panel control switch pass the component test?
- YES : Go to E10.
- NO : INSTALL a new roof opening panel switch. TEST the system for normal operation.
- E10 CHECK CIRCUIT (VT) FOR AN OPEN OR SHORT TO GROUND
- Disconnect: Roof Opening Panel Module Connector
- Connect: Roof Opening Panel Switch Connector
- Measure the resistance between the roof opening panel module connector, pin 3, circuit (VT), harness side and ground with the roof opening panel control switch at rest, and then while pressing the roof opening panel switch to the CLOSE position.
- Is the resistance greater than 10,000 ohms with the switch at rest, and less than 5 ohms with the switch in the CLOSE position?
- YES : Go to E11.
- NO : REPAIR the circuit. TEST the system for normal operation
- E11 CHECK CIRCUIT (WH) FOR AN OPEN OR SHORT TO GROUND
- Measure the resistance between the roof opening panel module connector, pin 2, circuit (WH), harness side and ground with the roof opening panel control switch at rest, and then while pressing the roof opening panel switch to the OPEN position.
- Is the resistance greater than 10,000 ohms with the switch at rest, and less than 5 ohms with the switch in the OPEN position?
- YES : INSTALL a new roof opening panel module. REFER to Roof Opening Panel Module . TEST the system for normal operation.
- NO : REPAIR the circuit. TEST the system for normal operation.
