generator output line and ground line in good condition?
If Yes, then go to next step. If No, check the generator output line and ground line.
8. Is the output current normal? If Yes, then go to next step. If No, then check the generator.
9. Is the regulated voltage normal? If Yes, then go to next step. If No, then check the generator.
10. Is the voltage drop in the generator output line normal? If Yes, then generator is normal. Check other systems. If No, then check the output line.

3. Check the basic ignition timing.
Standard value: 5° BTDC+/-3°
4. Start the engine.
5. Run the engine at idle for 2 minutes.
6. Check the idle speed. Select item number 22 and take a reading of the idle
speed.
Curb idle speed: 680+/-100 r/min
7. If the idle speed is outside the standard value, refer to MULTIPORT FUEL

INTRODUCTION TO HEATER, AIR CONDITIONING AND VENTILATION DIAGNOSISAir is drawn into the heater assembly from either the outside, or from the inside of
the passenger cabin if DEFROST, maximum cooling or RECIRCULATION are
selected. The air is then forced through the evaporator where heat is removed,
cooling and de-humidifying the air. Depending on the temperature selected, a
portion of this air is then forced through the heater core to achieve the selected
discharge temperature.
If the system does not cool properly, look for a problem with the refrigerant, blower
or air distribution systems. If the system does not heat properly, look for a problem
with the coolant, blower or air distribution systems. In either case all system fuses,
circuit breaker and relays should be checked. HEATER, AIR CONDITIONING AND VENTILATION DIAGNOSTIC TROUBLESHOOTING
STRATEGY Use these steps to plan your diagnostic strategy. If you follow them carefully, you
will be sure that you have exhausted most of the possible ways to find a heater, air
conditioning and ventilation fault.
1. Gather information from the customer.
2. Verify that the condition described by the customer exists.
3. Find the malfunction by following
SYMPTOM CHART

4. Verify that the malfunction is eliminated.
