Neon L4-2.0L DOHC (1996)
Keyless Entry: Description and Operation
Illuminated Entry
CIRCUIT OPERATION
When the RKE module determines a need for the interior lamps to be turned ON, the module energizes the relay connecting circuits M23 and Z2.
The M23 circuit is the ground side for many of the vehicles interior lamps.
The Z2 circuit connects to the instrument panel left center support.
Panic Function
CIRCUIT OPERATION
When the operator activates the panic function of the system the RKE module grounds the appropriate relays connecting circuits F35 and L4 to
feed the headlamps, and F35 to L7 to feed the parking lamps.
Power Door Locks
CIRCUIT OPERATION
Power for the Remote Keyless Entry (RKE) module is supplied from three sources.
Power is supplied to the RKE module on circuit G5. This circuit is protected by a 5 Amp fuse located in cavity 11 of the fuse block. Power for the
fuse is supplied from the ignition switch on circuit A21. This circuit is HOT in the START and RUN position.
Power for the A21 circuit is supplied by circuit A1. This circuit is HOT at all times and is protected by a 30 Amp fuse located in the Power
Distribution Center (PDC).
Circuit F35 supplies battery voltage to the RKE module. This circuit is HOT at all times and is protected by a 20 Amp fuse located in cavity 3 of
the fuse block. Power for the fuse is supplied on circuit A3. The A3 circuit is protected by a 40 Amp fuse located in the PDC.
The F35 circuit is used to supply power for the contact side of several relays internal to the RKE module.
Power is also supplied by circuit M1. This is the Ignition-Off Draw (IOD) circuit and is protected by a 10 Amp fuse located in cavity 13 of the
Power Distribution Center (PDC).
Time Out Relay
CIRCUIT OPERATION
The time out relay is located in the fuse block and is used to control the ground path for various interior lamps. It will also turn the lamps OFF
after a specified period of time, and works with the Remote Keyless Entry (RKE) system for illuminated entry.
Circuit M2 connects to the relay and supplied a ground path through the door ajar switches.
Circuit M1 is used to supply battery voltage to the relay. This circuit is produced by a 10 Amp fuse located in cavity 13 of the Power Distribution
Center (PDC).
Circuit M32 is connected from the relay to the various interior lamps and RKE module.
Using Door Lock Switches
CIRCUIT OPERATION
Operation of the lock and unlock functions is the same as systems without Remote Keyless Entry (RKE). The only change between the systems is
all of the lock and unlock circuits pass through the RKE module.
Left Door Unlock
CIRCUIT OPERATION
When the operator selects left front UNLOCK the Remote Keyless Entry (RKE) module energizes the left front unlock relay connecting circuits
F35 and P34. Circuit P34 connects from the module to the door lock motor.
Ground for the motor is supplied on circuit P33 through a bus bar in the right switch to circuit P35. The P35 circuit connects from the switch to the
LOCK-ALL relay in the RKE module. Ground is passed through the normally CLOSED contacts in the relay to the left door switch.
Ground is passed through a bus bar in the switch to circuit Z8. This circuit terminates at the instrument panel left center support.
Lock-All
CIRCUIT OPERATION
When the operator selects LOCK ALL the Remote Keyless Entry (RKE)module energizes the lock all relay connecting circuits F35 and P35.
