What does this fault code mean?

The engine control module (ECM) drives the leakage diagnosis pump and checks the drive signal to it. The code is set when the control module finds a fault on that signal, and here the signal is too low. The leakage diagnosis is then interrupted.

Possible causes

The signal wire to the leakage diagnosis pump is short-circuited to ground
Open circuit in the signal wire
Damaged leakage diagnosis pump

What you can do

1Check that the relevant fuses are intact; their locations are shown in the car's owner's manual
2Read and clear the code, then check whether it returns
3Check the connector to the leak diagnostic unit for loose contacts and oxidation
4Follow the signal wire to the leak diagnostic unit and look for chafing and pinching, especially where it may have touched the body
5Use a multimeter to check that the signal wire to the leak diagnostic unit has no contact with ground (the body) and no open circuit
6If the fault returns, have a workshop with diagnostic equipment check the pump and the wiring

Symptoms you may notice2
