OBD DOWNSTREAM OXYGEN SENSOR HEATING CIRCUIT
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the downstream oxygen sensor and its connections.
Repair if necessary.
With the ignition on, check for + 12 V feed on track A of the downstream oxygen sensor connector.
If +12V is not present:
– disconnect the battery,
– disconnect the CN connector in the Protection and Switching Unit,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check the continuity on the following connection:
Protection and Switching Unit, connector CN,
track 6track A of the downstream oxygen sensor
Reconnect the Protection and Switching Unit connector and reconnect the battery.
With the ignition on, if the +12V is still not present on the downstream oxygen sensor connector, there is a fault
in the Protection and Switching Unit.
Contact the Techline.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the Universal bornier, check the insulation and continuity on the following connection:
Injection computer, connectorC, track L3 track B of the downstream oxygen sensor
Repair if necessary.
Measure the heating resistance between tracks A and B of the downstream oxygen sensor.
Replace the downstream oxygen sensor if the resistance is not approximately 9Ω at 20°C.
If the fault is still present, replace the downstream oxygen sensor.
AFTER REPAIRRepeat the conformity check from the start.

CRUISE CONTROL/SPEED LIMITER BUTTONS
NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
INACTIVEStatus ET703 becomes "INACTIVE" when none of the cruise control/speed limiter
buttons is pressed. These buttons are located on the steering wheel.
If status ET703 does not display "INACTIVE",
●check the condition of the cruise control/speed limiter +/- button and the condition of
its connector,
●check the condition of the cruise control/speed limiter R/0 button and the condition of
its connector.
INCREASEStatus ET703 becomes PLUS when the cruise control/speed limiter + button is pressed.
This button is on the steering wheel, on the left-hand side.
If status ET703 does not display PLUS, check the condition of the cruise control/speed
limiter +/- button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 Mechanical, 88C,
Airbag and seat belt pretensioners, Driver's front airbag, Removal - Refitting)
Measure the resistance on the following connection with the "+" button pressed:
Injection computer,
connector A, black, 32-track track D2 "+/-" button track 2.
connector A, black, 32-track track D3 "+/-" button track 1.
If the resistance is not approximately 300 Ω, check the continuity of the connection when
the button is not pressed.
If there is continuity, replace the +/- control button.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

Injection computer,
connector A, black, 32-track track D2 "+/-" button track 2.
connector A, black, 32-track track D3 "+/-" button track 1.
If the resistance is not approximately 100Ω, check the continuity of the connection when
the button is not pressed.
If there is continuity, replace the "+/-" control button.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
RESUMEStatus ET703 becomes RESUME when the cruise control/speed limiter R button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not change to RESUME, check the condition of the cruise control/
speed limiter R/0 button, and the condition of its connector. Repair if necessary.
To carry out these checks and measurements in complete safety, observe the
recommendations for removing the driver's front airbag (see MR 364 Mechanical, 88C,

Replace the downstream oxygen sensor.
If the fault is still present, the catalytic converter is certainly damaged.
If the catalytic converter is defective, determine the cause of the destruction, otherwise the new catalytic
converter may be damaged in turn.
Remove the catalytic converter.
Various things may destroy a catalytic converter:
–deformation (impact),
–thermal shock (cold water splashed onto a hot catalytic converter can damage it),
–defective injector or ignition: the catalytic converter is damaged by contact with fuel (coil fault, coil control fault,
injector jammed open),
–injector leak,
–abnormal oil or coolant consumption (defective cylinder head gasket),
–use of a fuel additive or other equivalent product (obtain information from the customer because this type of
product can contaminate the catalytic converter and render it useless sooner or later).
Look up the service history of the vehicle or, if this is not possible, ask the customer if the vehicle has had injection
or ignition faults.
If the cause of the catalytic converter damage has been found and the fault has disappeared, replace the
catalytic converter.
AFTER REPAIRRepeat the conformity check from the start.
