IEM-B201211 - Phase Current Sensors. General Electrical Failures. Circuit short to ground
System
Unknown System / Manufacturer Specific
Volvo models this fault code applies to
Applies to the following models:
1 modelV60 (2011–)
Show models by year and engine (2)
What does this fault code mean?
The phase current sensor in the voltage converter (ISC) gives a signal that is missing or incorrect. The code indicates a short to ground. The cause lies in the ISC. Electric propulsion is then not possible.
Possible causes
- Internal fault in the voltage converter (ISC)
What you can do
- 1Have a workshop check the phase current sensor in the voltage converter (ISC). High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: read the phase current in live data while the car is in drive mode and see whether any phase is missing a value
- 3Do not carry out any work on the high voltage system yourself
- 4After the repair, check that the code is not stored again
Symptoms you may notice4
- Text window and warning symbol with a text message
- Drive mode PURE disengages automatically or is unavailable
- Drive mode AWD disengages automatically or is unavailable
- Drive mode HYBRID: the combustion engine runs all the time or too often
What the fault can affect2
- Electric propulsion is not possible
- Brake energy regeneration from the electric rear axle is not possible
General guidance for car owners. Diagnosis on the car can point to a different cause.
