–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.

PRESENT
OIL PRESSURE SENSOR
1.DEF: Signal incoherent
NOTESSpecial note:
This check must be carried out with the engine stopped.
1.DEF
NOTESThe fault is declared present if the oil pressure sensor is not
detected as closed when the engine is stopped.
Top up the oil level before starting the check.
Look for any damage to the wiring harness and check the condition and connection of the oil pressure switch
and its connections.
Look for possible damage to the wiring harness, check the connection and condition of the instrument panel
connector.
If there is a repair method (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair)
repair the connector, otherwise replace the wiring.
Check the insulation and continuity of the following connection:
Connection 28A between component 205 and component 247.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
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.

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.
