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

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.

What Is Auto-Start-Stop
The system is designed to help reduce fuel consumption and CO2 emissions by stopping the engine when it is idling, for example at traffic lights.
Auto-Start-Stop Precautions
WARNING: Apply the parking brake, shift into park (P), switch the ignition off and remove the key before you leave your vehicle. Failure to follow this instruction could result in personal injury or death.
WARNING: Apply the parking brake, shift into park (P), switch the ignition off and remove the key before you open the hood or have any service or repair work completed.
