9 | Replace the faulty headlamps. Did you complete the replacement? | -- | System OK | --
10 |

1. Disconnect the headlamp combination switch connector.
2. Put the switch in the high-beam position.
3. Use an ohmmeter to check the continuity of the headlamp switch between terminals 7 and 4 (terminal 2 if hatchback).

Does the ohmmeter indicate the specified value?

0 Ω
