IMPORTANT
To remove or check the cruise control/speed limiter control switches you need to remove the airbag (See
MR 364 or 370 Mechanics, 88C, Airbag and pretensioners).
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is present after a road test using the cruise control then the speed limiter
function.
Check the cleanliness and condition of the increase switches at the steering wheel and their connections.
Repair if necessary.
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Injection computer, connectorA, track D2 track 2 of the steering wheel control switch
Injection computer, connectorA, track D3 track 1 of the steering wheel control switch
Repair if necessary.
If the fault is still present, deal with the other faults then proceed to the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

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.

CONTINUED 1
DECREASEStatus ET703 becomes MINUS 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 change to MINUS, 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 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 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,
Airbag and pretensioners, Driver's front airbag, Removal - Refitting)
Measure the resistance of the following connection with the "R" 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 900 Ω, check the continuity of the connection when
the button is not pressed.
If there is continuity, replace the "R/0" 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.

SUSPENDStatus ET703 becomes SUSPEND when the cruise control/speed limiter 0 button is
pressed. This button is located on the steering wheel, to the right.
If status ET703 does not change to SUSPEND, check the condition of the cruise control/
speed limiter R/0 button, and the condition of its connector.
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,

connector A, black, 32-track track D3 "+/-" button track 1.
If the resistance is not approximately 0 Ω, replace the R/0 control button.
If there is continuity, replace the "R/0" 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.
