Pinpoint Test E: A Single Power Window is Inoperative - RH Front, SE, SEL

Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number

Normal Operation

The RH front window control switch receives high current power through circuit CBP47 (GN/BU) whenever the accessory delay relay is active. The RH front window control switch receives low current power through circuit CPW14 (VT/WH) whenever the window lock switch on the LH front window control switch is set to the UNLOCK position and the accessory delay relay is active. Ground is provided to the RH front window control switch through circuit GD145 (BK/BU). When operating the RH front window in the down direction, the RH front window control switch supplies power to the RH front window motor through circuit CPW19 (VT) and ground through circuit CPW20 (WH/OG).

When operating the RH front window in the up direction, the RH front window control switch provides power to the RH front window motor through circuit CPW20 (WH/OG) and ground through circuit CPW19 (VT).

RH Front Window Operation From LH Front Switch

When the RH front power window is operated in the down direction from the LH front window control switch, a low current voltage is sent to the RH front window control switch through circuit CPW12 (GN/OG). The RH front window control switch integral electronics then supply high current power to the RH front window motor through circuit CPW19 (VT). Ground is provided to the RH front window motor from the RH front window control switch through circuit CPW20 (WH/OG).

When the RH front power window is operated in the up direction from the LH front window control switch, a low current voltage is sent to the RH front window control switch through circuit CPW13 (BN/YE). The RH front window control switch integral electronics then supply high current power to the RH front window motor through circuit CPW20 (WH/OG). Ground is provided to the RH front window motor from the RH front window control switch through circuit CPW19 (VT).

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- LH front window control switch

- RH front window control switch

- RH front window motor

PINPOINT TEST E : A SINGLE POWER WINDOW IS INOPERATIVE - RH FRONT, SE, SEL

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.

E1 CHECK THE RH FRONT POWER WINDOW OPERATION FROM LH FRONT CONTROL SWITCH

- Ignition ON.

- Attempt to operate the RH front window from the LH front window control switch.

Does the RH front window operate when using the LH front window control switch?

Yes
GO to E2.

No
GO to E4.

E2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE

- Disconnect: RH Front Window Control Switch C604.

- Ignition ON.

- NOTE: Make sure the LH window control switch lockout switch is in the UNLOCK position.
Measure the voltage between RH window control switch C604-3, circuit CPW14 (VT/WH), harness side and ground.






Is the voltage greater than 10 volts?

Yes
INSTALL a new RH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.

No
GO to E3.

E3 CHECK THE LH FRONT WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: LH Front Window Control Switch C504.

- Carry out the LH front window control switch component test.

Did the LH front window control switch pass the component test?

Yes
REPAIR open in circuit CPW14 (VT/WH). TEST the system for normal operation.

No
INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.

E4 CHECK THE RH FRONT POWER WINDOW OPERATION FROM RH FRONT CONTROL SWITCH

- Ignition ON.

- Attempt to operate the RH front window from the RH front window control switch.

Does the RH front window operate when using the RH front window control switch?

Yes
GO to E5.

No
GO to E6.

E5 CHECK CIRCUITS CPW13 (BN/YE) AND CPW12 (GN/OG) FOR AN OPEN

- Measure the resistance between RH front window control switch C604-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504-11, circuit CPW13 (BN/YE), harness side.





- Measure the resistance between RH front window control switch C604-4, circuit CPW12 (GN/OG), harness side and LH front window control switch C504-10, circuit CPW12 (GN/OG), harness side.





Are the resistances less than 5 ohms?

Yes
INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.

No
REPAIR the circuit(s). TEST the system for normal operation.

E6 CHECK THE HIGH CURRENT POWER TO THE RH WINDOW CONTROL SWITCH

- Ignition OFF.

- Disconnect: RH Front Window Control Switch C604.

- Ignition ON.

- Measure the voltage between RH front window control switch C604-5, circuit CBP47 (GN/BU), harness side and ground.





Is the voltage greater than 10 volts?

Yes
GO to E7.

No
VERIFY Smart Junction Box (SJB) circuit breaker 47 (30A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.

If not OK, Refer to the Wiring Diagrams to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation. Diagrams By Number

E7 CHECK THE GROUND TO THE RH WINDOW CONTROL SWITCH

- Ignition OFF.

- Measure the resistance between RH front window control switch C604-8, circuit GD145 (BK/BU), harness side and ground.





Is the resistance less than 5 ohms?

Yes
GO to E8.

No
REPAIR the circuit. TEST the system for normal operation.

E8 CHECK THE RH FRONT WINDOW CONTROL SWITCH

- Carry out the RH front window control switch component test.

Did the RH front window control switch pass the component test?

Yes
GO to E9.

No
