Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Keyless Entry Keypad
The keyless entry keypad is hardwired to the BCM . The BCM interprets the inputs from the keyless entry keypad and then controls the associated operation. The keyless entry keypad is illuminated for 5 seconds when any button is pressed. The BCM requests the illuminated entry feature to turn the interior lamps on when a valid entry code is received. If a lock all doors code is entered, the illuminated entry feature turns off.
The keyless entry keypad supplies a signal to the BCM when the buttons are pressed. The BCM then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors. On vehicles with memory, the keyless entry keypad also causes the BCM to send an MS-CAN message to the DSM to activate all memory features to the positions associated with the personal entry code entered on the keypad.
