1 CHECK TRANSMITTER BATTERY.
1) Remove the battery from transmitter. to SL-41, REMOVAL, Keyless Transmitter.>
2) Check the battery voltage. INSPECTION, Keyless Transmitter.>
NOTE:
If the transmitter battery voltage is 2.5 V or less,
the range of transmission becomes very short.Is the voltage more than 2.5 V? If further inspec-
tion is necessary,
refer to “SYMP-
TOM CHART”.

CRUISE CONTROL SYSTEM (DIAGNOSTIC)
Diagnostic Procedure with Symptom
Step Check Yes No
1 CHECK POWER SUPPLY.
1) Turn the ignition switch to OFF.
2) Disconnect the cruise control module har-
ness connector.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.
Connector & terminal
(B94) No. 12 (+) — Chassis ground (
−):Is the voltage more than 10 V? Go to step 2. Check the fuse
No. 18 (in fuse &
relay box).
 Check the har-
ness for open or
short between
cruise control
module and fuse &
relay box.
2 CHECK GROUND CIRCUIT.
1) Turn the ignition switch OFF.
2) Measure the resistance between harness
connector terminal and chassis ground.
Connector & terminal
(B94) No. 6 — Chassis ground:Is the resistance less than 10
Ω?Power supply and
ground circuit are
OK.Repair the har-
ness.

CC(H4SO)-15
CRUISE CONTROL SYSTEM (DIAGNOSTIC)
Diagnostic Procedure with Symptom
C: CHECK CRUISE CONTROL MAIN SWITCH
TROUBLE SYMPTOM:
Cruise control main switch is not turned ON and cruise control cannot be set.
NOTE:
When the main relay (built-in cruise control module) operates, the main switch circuit is in normal condition.
The main relay operation can be checked by hearing the operation sound.
This operation sound will be heard when the ignition switch and cruise control main switch is turned to ON.
