Pinpoint Test F: The Short Drop Windows Do Not Operate Correctly
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information [1][2]Diagrams By Number.
Normal Operation
The short drop window feature is activated when one (or both) of the doors are opened, which opens a door ajar switch. When the driver door is opened (opening the driver door ajar switch), a signal on circuit CPL26 (GN/VT) is interpreted by the driver window motor that the driver door is open. The driver window motor then carries out the short drop function on the driver window. When the passenger door is opened (opening the passenger door ajar switch), a signal on circuit CPL31 (WH) is interpreted by the passenger window motor that the passenger door is open. The passenger window motor then carries out the short drop function on the passenger window. This feature is on both the coupe and the convertible.
This pinpoint test is intended to diagnose the following:
- Window motor not initialized
- Wiring, terminals or connectors
- Door ajar switch
- Window motor
PINPOINT TEST F : THE SHORT DROP WINDOWS DO NOT OPERATE CORRECTLY
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
F1 VERIFY THE DOOR AJAR SWITCH OPERATION
- Open and close the driver door and view the interior lamps operation.
- Open and close the passenger door and view the interior lamps operation.
Do the interior lamps operate correctly?
Yes
GO to F2.
No
REFER to Lighting and Horns to continue the diagnosis of the interior lamps.
F2 CARRY OUT THE WINDOW MOTOR INITIALIZATION
- Ignition ON.
- Carry out the Window Motor Initialization .
Does the short drop window feature operate correctly?
Yes
The system is operating correctly at this time. INFORM the customer of the short drop window feature. REFER to the Owner's Literature.
No
For the driver window, GO to F3.
For the passenger window, GO to F4.
F3 CHECK CIRCUIT CPL26 (GN/VT) FOR AN OPEN
- Ignition OFF.
- Disconnect: LH Door Ajar Switch C501.
- Disconnect: LH Front Window Motor C518.
- Measure the resistance between LH front window motor C518-7, circuit CPL26 (GN/VT), harness side and LH door ajar switch C501-5, circuit CPL26 (GN/VT), harness side.
Is the resistance less than 5 ohms?
Yes
INSTALL a new LH front window motor. REFER to Window Regulator Motor - Front Door . TEST the system for normal operation.
No
REPAIR the circuit. TEST the system for normal operation.
F4 CHECK CIRCUIT CPL31 (WH) FOR AN OPEN
- Ignition OFF.
- Disconnect: RH Door Ajar Switch C603.
- Disconnect: RH Front Window Motor C623.
- Measure the resistance between RH front window motor C623-7, circuit CPL31 (WH), harness side and RH door ajar switch C603-5, circuit CPL31 (WH), harness side.
Is the resistance less than 5 ohms?
Yes
INSTALL a new RH front window motor. REFER to Window Regulator and Motor - Front Door . TEST the system for normal operation.
No
REPAIR the circuit. TEST the system for normal operation.
