TYPE 1 TYPE 2
BODY ELECTRICAL SYSTEM 8-3
KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.
DIAGNOSIS
KEYLESS ENTRY SYSTEM (IF EQUIPPED)

Replace.
NOTE:

The operation distance of this system varies depending on the position where the transmitter is oper-
ated, at the front side, the rear side or the lateral side. The distance can be affected by radio noises from
a TV station, a power plant, a broadcasting station and so forth.

INSPECTION
1) Warm up ECT sensor (1) observing resistance between sensor
terminal (2) and sensor unit (1). Resistance should be de-
creased with increase of its temperature.
2) Check resistance between sensor terminal (2) and sensor unit
(1). If check result is not as specified below, replace sensor.

STEPACTIONYESNO
11) Turn ignition switch ON.
Do other indicator / warning lights in
combination meter come ON?Go to Step 2.“IG” fuse blown, main fuse blown,
ignition switch malfunction,
“(d)” circuit between “IG” fuse
and combination meter or poor
coupler connection at
combination meter.
21) Turn ignition switch OFF and
disconnect connectors from ECM.
2) Check for proper connection to ECM
at terminal C02-18 for G10 engine or
C01-28 for G13B engine.
3) If OK, then using service wire, ground
terminal C02-18 for G10 engine or
C01-28 for G13B engine in connector
disconnected.
