–Illumination of the “battery charge” warning light:
Illumination of the “battery charge” warning light indicates the following statuses:
●Fixed illumination for three seconds when the + after ignition feed is switched on: Warning light test
phase by the instrument panel.
●Flashing: Low voltage.
If the “Stop” warning light and “Battery charge” warning light come on simultaneously, refer to the “Stop warning light
illumination” insert.
–Illumination of the “Oil pressure warning” warning light:
The “Oil pressure warning” warning light always comes on with the “Stop” warning light and the “Stop” buzzer
sounds. This warning light indicates a pressure fault in the engine lubrication circuit and indicates potential engine
damage.
This warning light comes on for 3 seconds when the + after ignition feed is activated (Test phase).
–Illumination of the “Coolant temperature warning” warning light:
The “coolant temperature warning” warning light always comes on with the “Stop” warning light and the “Stop”
buzzer sounds. This warning light indicates that the cooling circuit temperature is too high, and there is a risk of the
engine overheating and engine damage.
This warning light comes on for 3 seconds when the + after ignition feed is activated (Test phase).
–Illumination of the “ABS” warning light:
Illumination of the “ABS” warning light indicates the following statuses to the driver:
–Rapid flashing: ABS not configured.
–Slow flashing: ABS in configuration phase.
This warning light comes on for 3 seconds when the + after ignition feed is activated (Test phase).
If the “Service” warning light and “ABS” warning light come on simultaneously, refer to the “Service warning light
illumination” insert.

–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.
