VOLVO
IGM-P16272F - Module Supply Voltage Out Of Range. General Signal Failures. Signal erratic
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 high voltage generator control module (IGM) monitors its internal components and related functions. The code is stored when one or more of the control module's internal supply voltages is faulty. Although the code is named an erratic signal, it therefore applies to the supply voltages. The fault is only checked once the test has started at ignition on.
Possible causes
- The voltage supply cable is short-circuited to ground or to voltage
- Break in the voltage supply cable
- Break in the feed that comes from the system relay
- Damaged voltage supply cable
- Internal fault inside the ISC voltage converter
What you can do
- 1Read out, clear the code and start the car to see whether it returns
- 2Have a workshop check the voltage supply cable and the supply from the system relay
- 3If the fault remains, have a workshop check the ISC voltage converter
- 4The high voltage system may only be handled by a workshop; do not work on it yourself
Symptoms you may notice5
- Warning symbol and text message in the display
- Warning about power supply problems from the alternator and charge regulator
- Charging of the high voltage battery while driving is absent, reduced or not working correctly
- High voltage battery is discharged or charges poorly
- HYBRID drive mode: the combustion engine is active all the time or too often
What the fault can affect1
- The high voltage battery cannot be charged by the combustion engine
