PINPOINT TEST A: HARD TO OPEN OR CLOSE A DOOR FROM EITHER DOOR HANDLE.jpg){kind=icon}
PINPOINT TEST A: HARD TO OPEN OR CLOSE A DOOR FROM EITHER DOOR HANDLE|
Normal Operation 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 Sources
|
||||
| A1 CHECK THE LATCH OPERATION FROM BOTH DOOR HANDLES | ||||
Does the door open normally from one of the door handles?
|
||||
| A2 CHECK THE LATCH OPERATION | ||||

PINPOINT TEST AP: P04B5, P04BA|
Refer to Wiring Diagrams Cell 116 for schematic and connector information. Normal Operation and Fault Conditions The PCM monitors the fuel filler door ajar switch and sets a DTC if it detects a failure of the fuel filler door ajar input based on conditions after a refueling event. If the fuel filler door is not fully closed after a refueling event, or the fuel filler door is open from erroneously pressing the fuel door release button, a message displays during the third drive cycle to indicate the fuel filler door is not closed and a DTC sets.
