What does this fault code mean?
This code concerns the right-hand turn signal. The control module has registered a fault, and the fault is intermittent. The cause may be a short to ground, an open circuit or a faulty shunt in the flasher circuit. The fault may not be present right now.
Possible causes

- Open circuit in the flasher circuit
- Faulty shunt in the flasher circuit
What you can do
- 1Check that the right turn signal works when switched on and flashes as it should
- 2Look for chafing and pinched spots on the wire to the right turn signal, especially at the lamp housings
- 3With the ignition off, use a multimeter to check that the wire is unbroken and has no contact with ground
- 4If the fault returns, have a workshop check the shunt in the flasher circuit
