| Autoclima self-diagnosis, electrical checking |
Note! | The air conditioner adjustment is still operative during self-diagnosis. |
| The Autoclima control and handling unit -J255- is separate from the indicator unit -E87-, and they are connected through the radio. |
| The control unit -J255- and the visualising front -E87- (display) receives the information from the electrical and electronic components (information transmitters), which is processed along the theoretical values. |
| The control unit outlet signals excite the electrical components (activators). |
| To be able to locate the cause quickly, should a component have a fault or a cable be broken, the control and indication unit is fitted with a fault memory that may be consulted using a fault reader -V.A.G. 1551- or with the vehicle system checker -V.A.G. 1552-. |
| If there are faults in the sensors or supervised components, these faults are stored in the fault memory with indication of the fault type. |
| Should a fault have been memorised that directly affects the working of the Autoclima, the indication unit display -E87- will blink for some 15 seconds after ignition. The control unit of the Autoclima can keep the working of the emergency programme stable for all faults. |
| To begin to locate faults, the self-diagnosis must be started and the information memorised with the -V.A.G 1551- must be consulted. |
| By means of a fault table, the information on faults leads us to indications on the possible causes and to more precise repair measures. |
