PINPOINT TEST H : CORNERING LIGHTS INOPERATIVE OR PERMANENTLY
ON

TEST CONDITIONS

DETAILS/RESULTS/ACTIONS

H1: DETERMINE THE CONDITIONS UNDER WHICH THE FAULT OCCURS

NOTE: The cornering lights are only switched on when the vehicle is driving at a speed of
less than 80 km/h and the low beam headlamps are switched on.
NOTE: The intensity of the cornering lights increases on a ramp up to the maximum
value when they are switched on, and it decreases on a ramp until the cornering lights
go out when they are switched off.
NOTE: Only the cornering light on the inside of the bend is switched on.

SWITCH ON the low beam.

1

Turn the steering approximately 30° to the left and
right.

2

CHECK the cornering lights on the left and right.

3

Are the cornering lights inoperative in both cases?
Yes

GO to H2

.

No

- Left-hand cornering light inoperative:

GO to H9

.

- Right-hand cornering light inoperative:

GO to

H12

.
