Power Windows - 'One Touch' Feature Inoperative
No: 76/18/03/NASRef:
Issue: 1
Date: 10/31/03
One Touch Window Operation Fault
AFFECTED VEHICLE RANGE:
New Range Rover (LM) All
SITUATION:
ONE TOUCH MODE FUNCTIONS INTERMITTENTLY OR IS DEACTIVATED
The front glass will not close in one touch mode or the window may open automatically after initially closing in one touch mode. The window channel seal may be compressing the anti-trap contact strip. This sends a false "trap" signal to the Body Control Unit (BCU), which in turn deactivates one touch mode functionality.
RESOLUTION:
INSPECT AND IF INDICATED REPLACE ANTI-TRAP SENSOR
Should a customer complain about these symptoms, follow rectification procedure below to ensure the anti-trap pinch strip is functioning correctly and is not compressed or pinched.
PARTS INFORMATION:
EJN000022PUY Finisher assembly - RH front door Qty 1
EJN000032PUY Finisher assembly - LH front door Qty 1

Inspect and install new anti-trap sensor. Perform resistance check
FAULT CODE S
DDW WARRANTY CLAIMS:
NOTE:
Claim 76.31.89/42 if the door finisher was removed but was not faulty and for connecting the anti-trap sensor.
DDW requires the use of casual part numbers. Labor only claims must show the causal part number with a quantity of zero.
Normal warranty policy and procedures apply.
Material allowance is included in labor operation.
REPAIR PROCEDURE
INVESTIGATE ONE TOUCH FUNCTION
1. Switch the ignition on.
2. Lower the window.
3. Lift the glass run seal (A in Figure 1) to release the anti-trap sensor (B in Figure 1)
4. Operate the window one touch mode.
5. If the window one touch mode operates, perform the following:
^ Rotate the anti-trap sensor inboard to move and reposition the active area of the anti-trap sensor away from the glass run seal.
^ Check the window one shot mode operation.
^ Close the window.
^ Switch off the ignition.
6. If the window one touch mode operates correctly, no further action is required.
7. If the window one touch mode does not operate, verify that anti-trap multiplug is connected as follows:
^ Refer to RAVE section 76.34.01 and remove the trim casing.
^ Verify that the anti-trap sensor is connected. (Arrowed in Figure 2).
^ If the anti-trap sensor multiplug is not connected, connect the multiplug.
^ Operate the window one touch mode and determine operability.
^ If the one shot mode operates correctly, install the trim casing as outlined in RAVE section 76.34.01.
8. If the anti-trap sensor multiplug is connected, test the anti-trap switch assembly as follows:
^ Refer to RAVE section 76.34.42 and remove the front door frame finisher.
^ Place the frame finisher on a bench and verify that the anti-trap sensor is not compressed.
^ Using a multimeter, check the resistance of the anti-trap sensor:
NOTE:
If the resistance is between 1100 ohms and 1300 ohms the anti-trap sensor has the correct values and the problem is elsewhere in the system.
^ If the resistance is below 1100 ohms, replace the anti-trap sensor/frame finisher.
NOTE:
The door frame finisher should be installed from the rear of the door to the front of the door, concluding the operation in the front corner. A rubber mallet can be used to knock the door frame finisher downwards into the front corner. This will ensure that the door frame finisher does not trap the pinch strip.
9. Install the door frame finisher following the procedures in RAVE section 76.34.42.
10. Check the window one touch mode operation to ensure proper operation.
