Pinpoint Tests

Hard To Open Or Close a Door From Either Door Handle

Normal Operations and Fault Conditions

The door latch can be actuated from the interior or exterior door handle. When actuated, the door latch releases and allows the door to open. If the door latch or the door hinges have insufficient lubrication or if the striker or door are misaligned, it causes extra force to be used when opening or closing the door.

Possible Causes


PINPOINT TEST A : HARD TO OPEN OR CLOSE A DOOR FROM EITHER DOOR HANDLE
A1   CHECK THE LATCH OPERATION FROM BOTH DOOR HANDLES
  • Open the door using both the interior and exterior door handles.

Does the door open normally from one of the door handles?

Yes If the door is difficult to open from the exterior door handle, GO to Pinpoint Test B
If the door is difficult to open from the interior door handle, GO to Pinpoint Test C
No GO to A2


A2   CHECK THE LATCH OPERATION
  • Open the door.
  • Using a screwdriver, fully close the latch (2 clicks).
  • Verify the latch releases easily while pulling on the interior/exterior door handle.

Does the latch release easily?

Yes GO to A4
No GO to A3


A3   CHECK THE LATCH OPERATION AFTER LUBRICATION
  • Lubricate the door latch.
    REFER to: Door Latch Lubrication (501-14 Handles, Locks, Latches and Entry Systems, General Procedures).
  • Using a screwdriver, fully close the latch (2 clicks).
  • Verify the latch releases easily while pulling on the interior/exterior door handle.

Does the latch release easily?

Yes The concern was caused by an insufficiently lubricated door latch.
No INSTALL a new door latch. For a front door latch,
REFER to: Front Door Latch (501-14 Handles, Locks, Latches and Entry Systems, Removal and Installation).

For a rear door latch,
REFER to: Rear Door Latch (501-14 Handles, Locks, Latches and Entry Systems, Removal and Installation).

The RKE Transmitter Has Poor Range Performance

Normal Operations and Fault Conditions


REFER to: Handles, Locks, Latches and Entry Systems - System Operation and Component Description (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).

For vehicles without push-button start, the Integrated Keyhead Transmitter (IKT) sends a radio signal to the BCM internal antenna. If the BCM detects the signal is from a programmed Integrated Keyhead Transmitter (IKT), it then carries out the selected action. The RKE radio signal has a normal operating range of 20 m (66 ft).

For vehicles with push-button start, the passive sends a radio signal to the Radio Frequency (RF) receiver. The Radio Frequency (RF) receiver sends the passive key information to the RFA module over a communication circuit.
