Alarm 34 (Radar faulty)
This alarm will be activated in the event that:
— The Radar is not connected
— The Radar has developed a fault
— The wiring is defective or short circuiting
— The electronic control unit is faulty
To remedy the trouble, check initially:
— That the connector of the device and the relative wiring are properly connected
— That the lead connecting the device to the electronic control unit is electrically sound
— That the lead is not short circuiting to earth
Alarm 35 (EPROM fault)
This alarm will be activated if parametric system configuration data stored by the internal memory of the
electronic control unit has become corrupted.
A fault of this nature can only be remedied by replacing the electronic control unit.
Alarm 51 (Steering sensor disconnected - versions with SBA system only)
This alarm will be activated in the event that:
— The sensor is faulty
— The relative wiring is not connected to the sensor
— The wiring is short circuited to earth
— The electronic control unit is faulty
To remedy the trouble, check initially:
— That the steering sensor connector and the relative wiring are properly connected
— That the lead connecting the sensor to the electronic control unit is electrically sound
— That the lead is not short circuiting to earth
Alarm 54 (Wrong wheel constant)
This alarm will be activated if the constant entered for the wheel speed sensor has been set to zero (signifying no
sensor), although the electronic control unit continues to receive signals confirming that the sensor is installed and
connected. In this instance the fault is due simply to incorrect programming of the electronic control unit.
To rectify the problem, check first that the wheel speed sensor is in fact mounted to the transmission housing, then
proceed as follows:
Connect the All Round Tester to the control unit;
—Access menu 1 (LIFT P.) and select option 2 (settings);
— With the settings menu displayed, enter the correct value of the "WHEELS" parameter, following the directions
given in the "Procedure for setting up the electronic lift".
