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

  • Door alignment
  • Door hinges
  • Striker adjustment
  • Door latch

PINPOINT TEST A: HARD TO OPEN OR CLOSE A DOOR FROM EITHER DOOR HANDLE
A1 CHECK THE LATCH OPERATION FROM BOTH DOOR HANDLES

      • re-configure module using as-built data if prior configuration is suspect
    • verify the module was not obtained from a like vehicle and installed into customer vehicle
      • return the swapped module to source vehicle and obtain new replacement module
  • Operate the system and determine if the observable symptom is still present.

Is the observable symptom still present?
Yes GO to AJ7
No The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

AJ7 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION
  • Disconnect and inspect all the SODR connectors.
  • Repair:
    • corrosion (install new connectors or terminals - clean module pins)
    • damaged or bent pins - install new terminals pins
    • pushed-out pins - install new pins as necessary
  • Reconnect the SODR connectors and make sure they seat and latch correctly.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new SODR .
REFER to: Side Obstacle Detection Control Module (SODCM) (419-04 Side and Rear Vision, Removal and Installation).
No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.


P1594 OR P1595

Normal Operation and Fault Conditions

When the BCM receives a request to remote start the vehicle, it first checks to make sure conditions exist to allow it to start (for example, the hood and doors closed, vehicle in PARK, no powertrain concerns). If the required conditions are correct, the BCM starts the vehicle and allows it to run for a predetermined amount of time, determined by the setting selected from the message center.


  PCM DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
P1594 Forced Engine Shutdown - Remote Start System Fault, No Unattended Vehicle Timeout Sets when the PCM detects the remote start has been active for more than 30 minutes continuously.
P1595 Forced Engine Shutdown - Remote Start System Fault, Transmission Range Not In Park Position Sets when the PCM detects the remote start is active with the transmission not in PARK.

Possible Causes

  • Network communication concern
  • Powertrain concern

PINPOINT TEST AK: P1594 OR P1595
AK1 CHECK FOR OTHER PCM (POWERTRAIN CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
  • Review the results from the PCM self-test.

Are any other PCM Diagnostic Trouble Codes (DTCs) present?
Yes DIAGNOSE all other PCM Diagnostic Trouble Codes (DTCs) first. REFER to the PCM DTC Chart in the appropriate 303-14 section.
No GO to AK2

AK2 CHECK FOR BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
  • Ignition ON.
  • Using a diagnostic scan tool, carry out the BCM self-test.

Are any BCM Diagnostic Trouble Codes (DTCs) present?
Yes REFER to the BCM DTC Chart in this section.
No GO to Pinpoint Test Z


B11DA:23

Normal Operation and Fault Conditions

The DDM sends voltage signals to the door latch to monitor the door lock cylinder lock/unlock position.


  DDM DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
B11DA:23 Driver Door Key Cylinder Switch: Signal Stuck Low Sets when the DDM detects a short to ground from one of the door lock cylinder input circuits.

Possible Causes

  • Wiring, terminals or connectors
  • Door latch
  • DDM

PINPOINT TEST AL: B11DA:23
AL1 CHECK THE OPERATION OF THE DOOR LOCK CYLINDER
  • Ignition OFF.
  • Lock and unlock the driver front door using the door lock cylinder.

Does the door lock cylinder lock and unlock the door?
Yes GO to AL2
No GO to Pinpoint Test G

AL2 CHECK THE DOOR LATCH FOR AN INTERNAL FAULT
  • Disconnect Left Front Door Latch C525 .
  • Ignition ON.
  • Using a diagnostic scan tool, clear the DDM Diagnostic Trouble Codes (DTCs).
  • Using a diagnostic scan tool, carry out the DDM self-test.

Is DTC B11DA:23 still present?
Yes GO to AL3
No INSTALL a new door latch.
REFER to: Front Door Latch (501-14 Handles, Locks, Latches and Entry Systems, Removal and Installation).

AL3 CHECK THE DOOR LOCK/UNLOCK INPUT CIRCUITS FOR A SHORT TO GROUND
  • Ignition OFF.
  • Disconnect DDM C501B .
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C501B-11   Ground
      C501B-4   Ground

Are the resistances greater than 10,000 ohms?
Yes GO to AL4
No REPAIR the circuit in question.

AL4 CHECK FOR CORRECT DDM (DRIVER DOOR MODULE) OPERATION
  • Disconnect and inspect all the DDM connectors.
  • Repair:
    • corrosion (install new connectors or terminals - clean module pins)
    • damaged or bent pins - install new terminals pins
    • pushed-out pins - install new pins as necessary
  • Reconnect the DDM connectors and make sure they seat and latch correctly.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new DDM .
REFER to: Driver Door Module (DDM) (419-10 Multifunction Electronic Modules, Removal and Installation).
No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
