What does this fault code mean?
The control module monitors the current to the power steering pump motor. The fault is stored when the current drawn by the pump motor stays too high for a longer period, which can be caused by a mechanical or hydraulic fault in the steering system.
Possible causes
- Mechanical or hydraulic fault in the steering system, for example a blocked hose, a blocked pipe or a fault in the steering gear
- Damaged power steering control module (PSCM)
What you can do
- 1Read the fault code, clear it and road test to see whether it returns
- 2Check mechanically that the steering does not bind and that hoses and pipes are not blocked, damaged or kinked
- 3If you have a diagnostic tool: read the pump motor current value in live data during a road test and check whether it rises abnormally when the wheel is turned
- 4If the fault returns and no fault is found, have a workshop check the control module, which may need replacing
- 5Steering is a safety system: avoid long drives with reduced steering and have a workshop check the car
Symptoms you may notice2
- Yellow warning symbol and message in the display
- Power steering assistance control does not work
