| TEST RESULTS |
| 0 | PRELIMINARY CHECK | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| Check that the engine coolant level is within the preset levels and that the coolant fluid circulates correctly in the system. | Move on to Step 1 | 1. Engine coolant level too low.2. Coolant does not circulate correctly: thermostat valve operating incorrectly. | 1. Top up to the correct level Op. 0010T84 COOLANT FOR AIR CONDITIONING SYSTEM - DEHYDRATE AND REPRESSURIZE check for leaks2. Follow See table K025 ENGINE COOLANT TEMPERATURE GAUGE NOT WORKING |
| 1 | CORRECT CLIMATE CONTROL SYSTEM OPERATION CHECK | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| For versions with automatic climate control:With the engine on, with the compressor off, in manual mode with the temperature set at maximum heat HI. Also place the re-circulation button in the closed position and set the fan speed at 10 bars with the distribution set to the front. Using the diagnostic equipment, check that the engine temperature has reached at least 70 °C. Check that the temperature of the air coming out of the front distribution vents is above 60 °C.For versions with manual climate control:With the engine on and the compressor off, in manual mode with the temperature knob at the maximum hot position. Also, set the recirculation button to the closed position, the fan speed to the 3rd setting and the distribution to front ventilation. Using the diagnostic equipment, check that the engine temperature has reached at least 70 °C. Check that the temperature of the air coming out of the front distribution vents is above 60 °C. | End of diagnosis | The temperature of the air coming out of the vents is not as desired. | Move on to Step 2 |
| 2 | CHECK USING DIAGNOSTIC EQUIPMENT | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| For versions with automatic climate control:Connect the diagnostic equipment and check:- that there are no errors at the air mixing actuators;- that there are no faults in the engine temperature sensor.For versions with manual climate control:Connect the Examiner diagnostic equipment and check that there are no errors in the engine temperature sensor. | For versions with automatic climate control:End of diagnosisFor versions with manual climate control:Move on to Step 5 | For versions with automatic climate control:1. Short circuit error at the air mixture actuators.2. Error in the engine temperature sensorFor versions with manual climate control:Error in the engine temperature sensor | For versions with automatic climate control:1. Move on to Step 32. Continue as instructed by the diagnostic equipment.For versions with manual climate control:Continue as instructed by the diagnostic equipment. |
| 3 | ELECTRICAL CIRCUIT CHECK | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| For versions with automatic climate control:Check whether the electrical wiring connections are loose.Disconnect and visually check for damage in the connector contacts/reconnect the connection to the actuator.Check the continuity/insulation of the electrical connection:- of the air mixing actuator/s;- on the control unit. | Move on to Step 4 | 1.Electrical connections loose or damaged.2. Electrical connection broken or not insulated. | 1.Restore the correct electrical connections See E6020 AIR CONDITIONING 2.Restore the continuity/insulation of the electrical connection See E6020 AIR CONDITIONING |
| 4 | CHECK ON CORRECT OPERATION USING DIAGNOSTIC EQUIPMENT | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| For versions with automatic climate control:Check for persistent errors in the air mixer actuators | End of diagnosis | Air mixing actuator error | Move on to Step 5 |
| 5 | CHECK ON CORRECT OPERATION OF MIXTURE ACTUATOR KINEMATIC COMPONENTS | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| For versions with automatic climate control:Visually check the correct operation of the mixer actuator for the climate control unit temperature control knob.Check whether the control on the control unit is interrupted by checking the electrical continuityFor versions with manual climate control:Visually check the correct operation of the mixer actuator for the climate control unit temperature control knob.Check whether the control on the control unit is interrupted by checking the electrical continuity | Move on to Step 6 | 1. Incorrect operation of actuator2. Physical impediment to the rotation of the flap.3. Incorrect operation of actuator for control on climate control system control unit. | For versions with automatic climate control:1. Replace the mixture actuator2. Replace the control unit.3. Replace the climate control system control unit Op. 5040D15 FOG LIGHT TRIM - R.R.For versions with manual climate control:1. Replace the mixture actuator2. Replace the control unit.3. Replace the climate control system control unit |
| 6 | AIR MIXTURE ACTUATOR FLAP CHECK | ALL OK | PROBLEMS ENCOUNTERED | ACTION |
|---|
| Check that the air mixture actuator flap completes its travel without any impediment | End of diagnosis | 1. Flap travel incomplete.2. Flap damaged.3. Kinematic components/gears damaged. | 1. Free the air mixture actuator flap from the hindrance2. Replace the flap.3. Restore the correct kinematic components |
