Test G: The Doors Do Not Lock/Unlock Using The Keyless Entry Keypad
PINPOINT TEST G: THE DOORS DO NOT LOCK/UNLOCK USING THE KEYLESS ENTRY KEYPADNormal Operation
The driver door module (DDM) monitors for a ground signal on reference circuits 78 (LB/YE), 79 (LG/RD) and 121 (YE/BK) for the keyless entry keypad. When an individual keypad button is pressed, an individual or a combination of the reference circuits are connected to ground. The DDM then determines which button was pressed based on which circuit(s) has a ground signal. The keypad is grounded through circuit 57 (BK). Once the DDM determines that the 5-digit personal entry code, or the factory set 5-digit entry code has been entered on the keypad, the DDM then energizes the driver door unlock relay to unlock the driver door.
To unlock all the doors, the 3/4 button must be pressed within 5 seconds of the 5-digit code being entered.
To release the luggage compartment lid, the 5/6 button must be pressed within 5 seconds of the 5-digit code being entered. For vehicles with a power luggage compartment lid, press the 5/6 button again to close the lid.
To lock all the doors, the 5-digit code does not need to be entered. Press the 7/8 and 9/0 buttons at the same time.
The keyless entry keypad has an anti-scan feature to help prevent theft. If a valid 5-digit code is not entered within 7 attempts (35 consecutive button presses), the keyless entry keypad will go into anti-scan. In anti-scan mode, the keypad illumination will flash and all input will be ignored except for pressing the 7/8 and 9/0 buttons, which will lock all doors.
- DTC B2695 (Keypad A Switch Circuit Failure) - is a continuous and on-demand DTC that sets when the DDM detects a short to ground on the keypad input circuit 78 (LB/YE). This DTC may also set if any keyless entry keypad button is pressed for longer than 2 minutes.
- DTC B2696 (Keypad B Switch Circuit Failure) - is a continuous and on-demand DTC that sets when the DDM detects a short to ground on the keypad input circuit 121 (YE/BK). This DTC may also set if any keyless entry keypad button is pressed for longer than 2 minutes.
- DTC B2697 (Keypad C Switch Circuit Failure) - is a continuous and on-demand DTC that sets when the DDM detects a short to ground on the keypad input circuit 79 (LG/RD). This DTC may also set if any keyless entry keypad button is pressed for longer than 2 minutes.
