Glass, Frames and Mechanisms
Pinpoint Test H: The One-Touch Up/Down Feature is Inoperative
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information Electrical Diagrams.
NOTE: De-initialize, then initialize the front window motor when any of the following occur:
- the LH or RH (MKX) or LH (Edge) front window motor is removed from the window regulator drum housing
- a new window regulator and/or motor is installed
- a new window glass is installed
- a new top run is installed
- any operation in which grease or lubricants are applied to the window regulator or glass run
NOTE: A new front window motor cannot operate in one-touch up or one-touch down mode until initialized. Refer to Window Motor Initialization .
Normal Operation
When the LH or RH (MKX) or LH (Edge) front window control switch is pressed or pulled to the second detent position (AUTO), the LH/RH front window control switch provides a ground signal to the LH or RH front window motor to request the one-touch up/down operation.
This pinpoint test is intended to diagnose the following:
- LH or RH front power window motor not initialized
- Battery power was lost while LH or RH front power window motor was operating
- Wiring, terminals or connectors
- Window control switch
- Power window motor
PINPOINT TEST H : THE ONE-TOUCH UP/DOWN FEATURE IS INOPERATIVE
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.
H1 CHECK FOR POWER (B+) LOSS DURING LH OR RH FRONT WINDOW OPERATION
- Verify if power (B+) was lost during LH or RH front window operation.
Was power (B+) lost while LH or RH front window was in operation?
Yes
RAISE the LH or RH front window to the fully CLOSED position. VERIFY the window glass stalls into the upper header seal. The front window should function normally. TEST the system for normal operation.
No
GO to H2.
H2 DE-INITIALIZE, THEN INITIALIZE THE FRONT MOTOR
- De-initialize the front window motor, then carry out the front window motor initialization procedure. Refer to Window Motor Initialization .
Is the one-touch down feature operating correctly?
Yes
The system is operating normally at this time. The front window motor lost initialization.
No
For LH window, GO to H3.
For RH window (MKX only), GO to H5.
H3 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535A and C535B (MKX) or C504A and C504B (Edge).
- Carry out the LH front window control switch component test.
Did the LH front window control switch pass the component test?
Yes
GO to H4.
No
INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
H4 CHECK THE AUTO CIRCUIT FOR AN OPEN
- Disconnect: LH Front Window Motor C540.
- Measure the resistance between LH front window motor connector C540-2, circuit CPW29 (VT/GY), harness side and LH front window control switch C535A-8 (MKX) or C504A-7 (Edge), circuit CPW29 (VT/GY), harness side.
Is the resistance less than 5 ohms?
Yes
INSTALL a new LH front window motor. REFER to Window Regulator Motor . TEST the system for normal operation.
No
REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.
H5 CHECK THE LH AND RH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C535A, C535B and RH Front Window Control Switch C648.
- Carry out the LH and RH front window control switch component tests.
Did the LH and RH front window control switches pass the component tests?
Yes
GO to H6.
No
INSTALL a new LH or RH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
H6 CHECK THE AUTO CIRCUIT FOR AN OPEN
- Disconnect: RH Front Window Motor C646.
- Measure the resistance between LH front window control switch C535A-1, circuit CPW31 (GN/WH), harness side and RH front window motor connector C646-2, circuit CPW31 (GN/WH), harness side; and between RH front window control switch C648-4, circuit CPW31 (GN/WH), harness side and RH front window motor connector C646-2, circuit CPW31 (GN/WH), harness side.
Is the resistance less than 5 ohms?
Yes
INSTALL a new RH front window motor. REFER to Window Regulator Motor . TEST the system for normal operation.
No
REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to Window Motor Initialization . TEST the system for normal operation.
