The power door lock system locks or unlocks all doors with
the actuation of a single door lock switch. Power is available at all times
from the DOOR LOCK fuse through CKT 1240 to the following components:
• | The left front door lock switch |
• | The right front door lock switch |
This voltage is also supplied to the following relays:
Both relays are grounded through CKT 150 at G201.
Each door lock switch has two contacts. When the upper portion of the
door lock switch is depressed in order to unlock the doors, one contact closes
in order to apply voltage to CKT 194. This voltage is applied to the
coil side of the door unlock relay. Since the coil in the relay is grounded
at all times through CKT 150 and G201, the coil is energized. The
relay switch contacts then close in order to apply voltage to CKT 294.
CKT 294 applies voltage to all the door lock motors, which are grounded
through the following components:
• | The normally grounded contacts of the door lock relay |
When the lower portion of the door lock switch is depressed in order
to lock the doors, the other switch contact closes in order to apply voltage
to CKT 195. This voltage is applied to the coil side of the door lock
relay. Since the coil in the relay is grounded at all times through CKT 150
and G201, the coil is energized. The relay switch contacts then close in
order to apply voltage to CKT 295. CKT 295 applies voltage
to all the door lock motors which are grounded through the following components:
• | The normally grounded contacts of the door unlock relay |
With Keyless Entry
When the vehicle is equipped with keyless entry, the following doors
operate as described above:
The left front door lock motor does not operate in the same manner.
When either door lock switch is moved to the LOCK position, the operation
is similar to the above operation, with the following exceptions:
• | The left front door lock motor receives ground through CKT 694. |
• | The left front door lock motor receives ground through the remote
control door lock receiver. |
If either door lock switch is moved to the UNLOCK position, the following
components receive voltage:
• | The remote control door lock receiver |
When the remote control door lock receiver receives the unlock signal,
the receiver then applies voltage to the left front door lock motor through
CKT 694. The motor is then grounded through CKT 295 as described
above. Refer to
