Test E: The Doors Do Not Lock/Unlock Using The Keyless Entry Keypad
PINPOINT TEST E: THE DOORS DO NOT LOCK/UNLOCK USING THE KEYLESS ENTRY KEYPADE1-E3:
E4-E6:
Normal Operation
The driver door module (DDM) monitors the keyless entry keypad through circuits 78 (LB/YE), 79 (LG/RD) and 121 (YE/BK). As each button is pressed, a connection to ground through individual resistors occurs. The DDM receives the ground signals from the keyless entry keypad and operates the locks accordingly.
DTC B2695 - is a continuous DTC that sets if the DDM detects that the keypad switch A is active for longer than 2 minutes. It is also an on-demand DTC that sets if the DDM detects that keypad switch A is active during the self-test. A short to ground on circuit 78 (LB/YE) may be detected by the DDM as an active switch.
DTC B2696 - is a continuous DTC that sets if the DDM detects that the keypad switch B is active for longer than 2 minutes. It is also an on-demand DTC that sets if the DDM detects that keypad switch B is active during the self-test. A short to ground on circuit 79 (LG/RD) may be detected by the DDM as an active switch.
DTC B2697 - is a continuous DTC that sets if the DDM detects that the keypad switch C is active for longer than 2 minutes. It is also an on-demand DTC that sets if the DDM detects that keypad switch C is active during the self-test. A short to ground on circuit 121 (YE/BK) may be detected by the DDM as an active switch.
Possible Causes
- Circuit 57 (BK) open
- Circuit 78 (LB/YE) open or short to ground
- Circuit 79 (LG/RD) open or short to ground
- Circuit 121 (YE/BK) open or short to ground
- Keyless entry keypad
- DDM
