–Illumination of the “Sinusoid” warning light:
Illumination of the “Sinusoid” warning light indicates the following statuses to the driver:
●Fixed illumination 3 seconds after + after ignition feed: Test phase by the instrument panel.
●Fixed illumination (If sequential gearbox configuration): Sequential gearbox overheating warning.
●Fixed illumination + buzzer (If sequential gearbox configuration): Increased sequential gearbox
overheating warning.
●Water in diesel fuel warning.
●Level 1 injection fault.
If the “Service” warning light and “Sinusoid” warning light come on simultaneously, refer to the “Service warning light
illumination” insert.
–Illumination of the “Stop” warning light:
Illumination of the “Stop” warning light alone characterises a warning light test phase by the instrument panel.
Outside of this condition, the “Stop” warning light is always associated with a “Stop” buzzer and another warning light
to indicate a fault.
“Stop” warning light + “Stop” buzzer:
–Major injection fault warning.
“Stop” warning light + “Stop” buzzer + “Brake” warning light:
–Brake circuit fault.
–Electronic Braking Distribution fault.
“Stop” warning light + “Stop” buzzer + “Battery charge” warning light:
–Battery charge warning.
“Stop” warning light + “Stop” buzzer + “Oil pressure warning” warning light:
–Oil pressure warning.
“Stop” warning light + “Stop” buzzer + “Coolant temperature warning” warning light:
–Coolant temperature warning.
“Stop” warning light + “Stop” buzzer + “Major electric power-assisted steering fault warning” warning light:
–Major electric power-assisted steering fault warning.

STOP WARNING LIGHT ACTIVATED BY THE SYSTEM
If the STOP WARNING LIGHT is illuminated, check for faults and check the conformity of the systems
concerned.
1 : Injection
2 : Coolant temperature
3 : Oil pressure
Perform fault finding on the injection system:
–Petrol: See 17B, Petrol injection,
–Diesel: See 13B, Diesel injection.
4 : Brake fluid level
See the interpretation of ET019 MINIMUM BRAKE FLUID LEVEL.
5 : Electronic Braking Distribution
Carry out fault finding on the ABS/ESP system (see 38C, Anti-lock braking system).
6 : Electric power assisted steering
Carry out fault finding on the EPAS system (see 36B, Power-assisted steering).
7 : Battery charge
Carry out fault finding on the charging circuit (see Technical Note 6014A, Checking the charging circuit).
If there are no faults, carry out a multiplex network check (see 88B, Multiplex).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
