VOLVO
IEM-B200729 - Insulated Gate Bipolar Transistor Temperature Sensor. General Signal Failures. Signal signal invalid
System
Unbekanntes System / Herstellerspezifisch
Volvo-Modelle, für die dieser Fehlercode gilt
Gilt für folgende Modelle:
1 ModellV60 (2011–)
Modelle nach Baujahr und Motor anzeigen (2)
Was bedeutet der Fehlercode?
The signals from the three temperature sensors inside the IEM differ too much from one another. The sensors measure the temperature of the high voltage transistors inside the control unit. The code is set with the ignition on once the control module's test has started. Electric propulsion is then not possible.
Mögliche Ursachen
- Damaged temperature sensor in the IEM
- Internal fault in the voltage converter (ISC)
Was Sie tun können
- 1If you have a diagnostic tool: compare the three temperature readings from the IEM in live data and see whether any of them clearly deviates from the others
- 2Have a workshop check the electric rear axle drive control module. The sensors sit inside it and it contains high voltage equipment. High voltage systems may only be handled by qualified personnel
- 3Do not carry out any work on the control module yourself
- 4After the repair, read out the fault codes and check that the code is not stored again
Symptome, die Sie bemerken können4
- Warning window with a warning symbol and text message
- Drive mode PURE disengages automatically or is unavailable
- Drive mode AWD disengages automatically or is unavailable
- Drive mode HYBRID: the combustion engine is running all the time or too often
Was der Fehler beeinflussen kann2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
Allgemeine Hinweise für Fahrzeughalter. Die Diagnose am Fahrzeug kann eine andere Ursache zeigen.
