Automatic Door Locks

Pontiac vehicles without keyless entry are equipped with the automatic door locks. CKT 275 (LT GRN) from the park/neutral position switch to the MALL allows this function. CKT 275 (LT GRN) provides battery voltage to the MALL module connector C2 terminal D6 whenever the gear selector is in the PARK position. The MALL module commands the doors to lock under the following conditions:
- The left door is closed.
- The vehicle is in RUN.
- The gear selector is shifted out of PARK.

If programmed to do so, the MALL module unlocks the doors when the gear selector is put back into PARK.
