Condition Code Numbers
Self-diagnosis of malfunction
The test light will flash if a malfunction is present.
Inspection Procedure
Self-diagnosis of malfunction
1. Locate the cruise control connector.
2. Connect a 1.4W test light between terminals f and d, with
connector attached to control unit.
Note
l There is no wire in terminal d of the connector. Push
the test light through the connector and touch the
corresponding pin on the control unit.
3. Turn the ignition switch to ON.
4. Turn the cruise control on by pressing the MAIN switch. (The
MAIN indicator lamp will come ON.)
5. Press and hold the RESUMElACCEL switch for more than
three second.
6. The test light will illuminate for 3 seconds and go out for
2 seconds.
7. The self-diagnostic system is activated and the test light will
flash if a problem is present.
8. Make note of the condition code number(s).
(Refer to the chart at the bottom of the page).
9. After retrieving the code(s), drive the vehicle at more than
16 km/h (lOmph), or press the MAIN switch to deactivate
self-diagnosis. (The MAIN indicator lamp will go OFF.)
Note
l The cruise control system will not operate when in
the self-diagnosis mode.

Inspection Procedure
Quick inspection of cruise control system
1. Locate the cruise control connector.
2. Connect a 1.4W test light between terminals f and d, with
connector attached to control unit. -1
Note
l There is no wire in terminal d of the connector. Push
the test light through the connector and touch the
corresponding pin on the control unit.
3. Turn the ignition switch to ON.
4. Verify that the MAIN switch is OFF. (The MAIN indicator lamp
is OFF.)
5. Press the RESUMElACCEL switch and the MAIN switch
simultaneously to activate the system inspection. (The MAIN
indicator lamp will come ON.)
6. Operate each switch as described below and verify the oper-
ation codes.
7. Press the MAIN switch to deactivate the system inspection.
(The MAIN indicator lamp will go OFF.)
Note
l The cruise control system will not operate when in
the self-diagnosis mode.

U TROUBLESHOOTING GUIDE
Symptom: Blower motor does not operate.
Normal operation of blower motor
Blower motor speed is controlled by the blower switch and a resistor assembly in the blower unit.
When the blower switch is in the OFF position, the motor ground circuit is open and the blower motor does
not operate. When the switch is in the first (Low) position, current flow from the blower motor is restricted
by the three resistors in the resistor assembly, and the blower motor turns at low speed.
Changing the blower switch to the second (Mid), third (High), or fourth (Super-high) positions causes the
circuit resistance to decrease, and the blower motor speed to become correspondingly faster.

2. If the reset button is not out, go to Step 2.
3. If the reset button is out, check for a short circuit in the har-
ness. Repair as necessary; then depress the reset button
to reset the circuit breaker.
Step 2 Measure voltage at blower motor
1. Turn the ignition switch ON.
2. Turn the blower switch to the fourth position.
3. Measure the voltage at the following terminal wires of the
blower motor connector.
