Troubleshooting
The electronic module does not change the engine speed in diagnosis
mode B
➤ Perform all the other diagnosis mode tests again to make sure that the
problem is not caused by the electrical connections or by the control ele-
ment.
➤ Switch the ignition off.
➤ Quit diagnosis mode.
➤ Leave the ignition switched off for several seconds.
➤ Press the SET button again and hold it down.
➤ Start the vehicle again to start diagnosis mode.
➤ Repeat diagnosis mode B again.
➤ Make sure the starter is not working.
➤ Check the plug connection to the electronic module, make sure the cables
are correctly positioned and pay attention to the colour code of the plug.
➤ Use a voltmeter to test that none of the cables in the wiring harness are
damaged.
The cruise control does not work evenly in control mode
➤ If the cruise control reacts too suddenly or the vehicle speeds up too much
in control mode, you must decrease the GAIN value (see "Setting the con-
trol sensitivity manually (GAIN mode)" on page 22).
➤ If the cruise control operates too slowly in control mode, you must in-
crease the GAIN value (see "Setting the control sensitivity manually
(GAIN mode)" on page 22).
