The LED on the electronic module does not light up when you apply the brake

NOTE For reasons of safety, the cruise control does not work when there are problems with the original brake light circuit. Therefore, check that the brake lights are working properly. ➤ Make sure the LED on the electronic module lights up when you press the buttons on the control element. ➤ If the LED does not light up, check the power supply and earth connection of the electronic module. There should be a voltage of +12 V on the orange cable when the igni- tion is switched on. The green cable should have a good earth connection. ➤ Check the connection of the brown and brown/white cable to the brake light switch using a voltmeter. Test the cables with the ignition switched on, because some brake light circuits are powered via the ignition. The brown/white cable of the electronic module should be connected to a brake light switch cable which is connected to either the permanent posi- tive terminal (terminal 30) or to the ignition (terminal 15). The brown cable should be connected to the brake light switch cable, which connects the brake light lamp and the brake light switch. This gives an earth signal from the brake light lamp supply cable when the brake pedal is not applied, and a positive signal (+12 V) when the brake pedal is applied. The LED does not flash when an engine speed signal is received (yellow cable) This is how to check whether the cruise control is receiving an incorrect engine speed signal: ➤ Check the engine speed signal using a voltmeter or an oscilloscope. ➤ Make sure the signal is between 6 V and 250 V and the frequency range is between 6 Hz and 488 Hz. ➤ Check that the yellow cable is not damaged and is properly connected to the engine speed signal. _Diag_MS880.book Seite 14 Donnerstag, 26. April 2012 7:32 19EN MagicSpeed MS880 Troubleshooting

➤ Test the engine speed signal on the electronic module of the cruise con- trol: – Connect the red cable of the voltmeter or oscilloscope to the yellow ca- ble in the connecting plug of the electronic module. – Connect the second cable of the voltmeter or oscilloscope to earth. ➤ Make sure the signal at the electronic module matches that of the vehicle. If the engine speed signal on the electronic module matches that of the vehi- cle, the fault may be due to an incorrect PPM setting. If you chose to record the travel speed or engine speed signal using the blue cable, the speed con- troller does not operate using the engine speed signal (yellow cable). ➤ To change the PPM setting, see “Starting automatic mode” on page 19 The LED does not flash when a travel speed signal is received (blue cable) This is how to check whether the cruise control is receiving an incorrect en- gine speed signal: ➤ Check the travel speed signal using a voltmeter or an oscilloscope. ➤ Make sure the signal is between 1.5 V and 24 V and the frequency range is between 6 Hz and 8.5 kHz. ➤ Check that the blue cable is not damaged and is properly connected to the travel speed signal. ➤ Test the travel speed signal on the electronic module of the cruise control: – Connect the red cable of the voltmeter or oscilloscope to the blue cable in the connecting plug of the electronic module. – Connect the second cable of the voltmeter or oscilloscope to earth. ➤ Make sure the signal at the electronic module matches that of the vehicle.

3 Setting the sensitivity

NOTE To begin one of the adjusting and teach modes you must always carry out the following procedure. For automatic mode (page 19), you first have to start the motor. For any of the other modes, you first simply have to switch the ignition off and on again. To start setup mode, proceed as follows: ➤ Depending on the mode, do one of the following: – For automatic mode: start the motor. – For the other modes: switch the ignition off and on again. ➤ Press the ON/OFF button on the control element. ➤ Apply the brake within one minute and hold it down. ➤ Press the setup button four times in rapid succession. ➤ Release the brake. ✓ You will hear four acoustic signals. ✓ You are now in setup mode and can set the cruise control.

3.2 Starting automatic mode

In automatic mode, the PPM and GAIN parameters are automatically syn- chronised with your vehicle. You can still fine-tune both parameters anytime. ➤ Start setup mode (“Starting setup mode” on page 19). ➤ Apply the brake and hold it down. ➤ Press the RES button twice. ✓ You will hear two low-pitched signals. ➤ Release the brake. ✓ You will hear two high-pitched signals. _Diag_MS880.book Seite 19 Donnerstag, 26. April 2012 7:32 19EN Setting the sensitivity MagicSpeed MS880

NOTE If you hear more than two signals, repeat the procedure. ➤ Drive the vehicle at a speed of 70 km/h to allow the PPM and GAIN para- meters to be set automatically. ➤ Press the SET button. ✓ The cruise control switches itself on. If the cruise control does not take on the speed gently or the save value is not applied: ➤ Press the SET button again to increase the value or ➤ ... press the RES button to decrease the value. ✓ You will hear a signal each time you press the button. The current value is indicated by the number of beeps (3 – 14 beeps). The factory setting is 5 beeps. ➤ Apply the brake to save the set values (PPM and GAIN). ✓ Normally, your cruise control should be ideally preset for your vehicle. ➤ Quit setup mode (“Quitting setup mode” on page 23). ➤ You can now use MagicSpeed MS880.

NOTE If, during operation, you notice that the vehicle reacts too slowly or too suddenly, or the speed is not being regulated correctly, you must set the control sensitivity manually (see “Setting the control sensitivity manually (GAIN mode)” on page 22). _Diag_MS880.book Seite 20 Donnerstag, 26. April 2012 7:32 19EN MagicSpeed MS880 Setting the sensitivity

3.3 Setting the sensitivity (INIT mode)

In INIT mode you can set the sensitivity of speed reaction. If the speed reg- ulator reacts to the speed too slowly you must increase the INIT value. If it reacts too suddenly to the speed, you must decrease the INIT value. ➤ Start setup mode (“Starting setup mode” on page 19). ➤ To set the sensitivity, apply the brake and hold it down. ➤ With the brake applied, press the RES button three times. ✓ You will hear a low-pitched signal each time you press the button. ➤ Release the brake. ✓ You will hear three high-pitched signals.

NOTE If you do not hear three signals, repeat the procedure. ➤ With the speed controller activated, drive at any speed above the activa- tion speed (40 km/h). ➤ Press the SET button until the speed regulator takes on the speed you are driving at. ➤ Switch off the speed regulator by applying the brake. ➤ Press the SET button. ✓ You will hear a high-pitched signal each time you press the button. ✓ The speed regulator gently takes on the speed.

NOTE The normal functions of the SET and RES buttons are disabled in this mode, which means you can use the buttons to make the set- tings. ➤ If the reaction to the speed is too slow, press the SET button to increase the INIT value. ➤ If the reaction to the speed is too sudden, press the RES button to de- crease the INIT value. ✓ You will hear a low-pitched signal each time you press the button. _Diag_MS880.book Seite 21 Donnerstag, 26. April 2012 7:32 19EN Setting the sensitivity MagicSpeed MS880

➤ To save the set sensitivity values, press the brake. ✓ If the INIT value is changed, the speed regulator calculates the optimum GAIN value and deletes the previous value in the control element. Normally, no more settings on the control element are required. Therefore, quit setup mode and test the speed controller in normal operation. ➤ If the speed regulator works too slowly or too suddenly in control mode, you must make the GAIN setting manually (see “Setting the control sen- sitivity manually (GAIN mode)” on page 22).

3.4 Setting the control sensitivity manually

(GAIN mode) The GAIN value must be increased if the vehicle slows down when the cruise control is activated or if it reacts too slowly, for example excess loss of speed driving uphill or excess acceleration driving downhill. The GAIN value must be decreased if the vehicle speeds up when the cruise control is activated or if it works too suddenly. Example: You set a speed of 70 km/h and the vehicle's speed fluctuates between 65 and 75 km/h during control mode. Normally the GAIN value ensures that the cruise control operates smoothly in control mode. To alter the GAIN value, proceed as follows: ➤ Start setup mode (“Starting setup mode” on page 19). ➤ Apply the brake and hold it down. ➤ With the brake applied, press the RES button four times. ✓ You will hear four low-pitched signals. ➤ Release the brake. ✓ You will hear four acoustic signals. ➤ Start the engine. ➤ Drive the vehicle at any speed above the activation speed (40 km/h) to set the GAIN value. ➤ Press the SET button. ✓ The cruise control switches itself on. ➤ Press the SET button again to increase the GAIN value or _Diag_MS880.book Seite 22 Donnerstag, 26.
