Fault diagnosis using the radio remote control TP5

4 Troubleshooting

TP5 radio remote control

(Order No: 22 1000 32 01 00)

If faults occur while the heater is running, they are displayed with “Err” after the mobile unit is activated.

After the diagnostics cable (bl/ws) has been connected and the first logs have arrived at the stationary unit, the diagnose can be carried out using the mobile unit of the TP5 radio remote control. The current fault “F0” is displayed. The stored faults “F1” to “F5” can be queried.

Please note!

• In order to carry out the diagnosis, the diagnostics cable (bl/ws) must be connected to the stationary unit and the heater cable harness. To this end, please refer to and follow the circuit diagram for the TP5 radio remote control and the heater. • If the diagnostics cable (bl/ws) is not connected, the “Diagnosis” menu is blocked. • Not only the defective component, but also a defective current circuit results in a fault being displayed. • In heaters with connected air pressure sensor the TP5 radio remote control cannot be used to perform diagnoses. The diagnostics unit or the EDiTH diagnostics tool must be used to perform the diagnosis.

The fault memory of the „air pressure sensor“ can be read out using the EDiTH diagnostics tool only. • Fault code, fault description, cause / remedial action are described on Pages 23 – 27. Button to activate / deactivate the mobile unit
