3. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Standard resistance: 12.5 -16.5 W
If resistance value is not as specified, replace the solenoid.
(c) Supply battery positive voltage between terminals.
If the solenoid does not operate, replace the solenoid.
4. INSPECT SHIFT LOCK CONTROL SWITCH
Inspect that continuity between at each terminal.

2. INSPECT WIRELESS DOOR LOCK TRANSMITTER
OPERATION
HINT:
Refer to ºWireless door lock control receiver and transmitter re-
placementº.
(a) Using a screwdriver, remove the cover.
(b) Remove the battery (lithium battery).
(c) Install a new or normal battery (lithium battery).
HINT:
When a new or normal battery can not be obtained, connect 2
new 1.5 V batteries in series, connect the battery (+) to the bat-
tery receptacle side terminal and battery (-) to the bottom termi-
nal, then apply 3 V voltage to the transmitter.
(d) In the location where is approx. 1 M away from driver's
outside handle in the right direction, face the key plate of
the transmitter to the vehicle, and check the transmitter
operation when pressing transmission switch on the side
of the transmitter body.
Standard:

Remote control of vehicle door lock can be operated.

LED lights up more than once.
HINT:

The minimum operation distance differs according to op-
erator, the way of holding, and location.

As weak wave is used, operation distance might be short-
ened when noise is detected in strong wave or used fre-
quency.

REPLACEMENT
1. REPLACE TRANSMITTER (LITHIUM) BATTERY
NOTICE:
Special caution should be taken for handling each compo-
nent as they are precision electronic components.
(a) Using a screwdriver, remove the cover.
NOTICE:
Do not pry out the cover forcibly.
HINT:
Push the cover with a finger as shown in the illustration, so that
there becomes clearance, then pry out the cover from that
clearance.
(b) Remove the transmitter.
(c) Remove the battery (lithium battery).
NOTICE:
Do not push the terminals with a finger.
If prying up the battery (lithium battery) forcibly to re-
move, the terminals are deformed.
(d) Install a battery (lithium battery) as shown in the illustra-
tion.
NOTICE:
Face the battery upward. Take care not to deform the termi-
nals.
(e) Assemble the transmitter to the key plate and the cover.
