3. SAFETY INSTRUCTIONS
The safety instructions must be followed at all times when working on components, to avoid damage or injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.
Procedure for disconnecting the battery:
– switch off the ignition,
– switch off all electrical consumers,
– Wait at least 1 minute for the electronic systems to switch off,
– disconnect the battery, starting with the negative terminal.

Windscreen washing/wiping
The UCH receives the wiper speed, windscreen wiper park position and windscreen washer signals.
This ensures the following functions:
– intermittent wiper speed,
– extended wiper time after washing,
– return to park position.
In the park position, the switch is closed to earth, and the UCH receives logical signal 0.
This function is only active if + after ignition feed is present.
When the + after ignition feed is switched on, if the windscreen wiper park position is not detected, the wiper motor
relay is held.
Operation is interrupted in the following cases:
– wiper request stopped or no request,
–+ after ignition feed switched off,
– UCH reads park position information.
Detection of the park position should be made during transition and not level, that is, if the wiper stalk is moved from
the intermittent position to the park position while the wiper blade is in the park position and the wiper motor is
running, it will not be stopped until the next reading of the park position. This condition is necessary in order to obtain
an exact park position.
Intermittent
The intermittent wiper speed function is only active if the + after ignition is present and if the switch is in the
intermittent position.
The time delay between two wipes is 5 seconds, and this cannot be modified by the diagnostic tool.
When the windscreen intermittent speed function is activated, the windscreen intermitted speed relay is held by the
UCH until the park position is detected. When the intermittent speed time delay has elapsed, the relay is held again
and the cycle begins again.
Extended wiper time after washing
The UCH does not manage the windscreen washer pump command, it only deals with the windscreen washer
command input to provide screen wiping and the extended wiper time after washing.
This function is only active if + after ignition feed is present.
After the washer pump is activated, the first wiping is performed after a time delay of 750 ms.
When the washing control is pressed briefly, the windscreen wiper performs 1 wiping cycle.
When the washing control is pressed for longer, the UCH activates the windscreen wiper throughout the washing
phase. At the end of the washing phase, the UCH counts the park position status changes in order to stop the
extended wiping phase.

Rear screen washing/wiping
The UCH controls a diode relay which is external to the UCH, by transmitting a + 12 V signal.
The drop in the voltage between the UCH supply voltage and this output should not exceed 2 V.
The UCH receives the intermittent wiper speed, rear wiper park and rear screen washer signals.
This ensures the following functions:
– intermittent wiper speed,
– extended wiper time after washing,
– return to park position.
In the park position, the switch is closed to earth, and the UCH receives logical signal 0.
This function is only active if + after ignition feed is present.
When the + after ignition feed is switched on, if the rear wiper park position is not detected, the wiper motor relay is
held.
Operation is interrupted in the following cases:
– wiper request stopped or no request,
–+ after ignition feed switched off,
– UCH reads park position information.
Detection of the park position should be made during transition and not level, that is, if the wiper stalk is moved from
the intermittent position to the park position while the wiper blade is in the park position and the wiper motor is
running, it will not be stopped until the next reading of the park position. This condition is necessary in order to obtain
an exact park position.
Intermittent
The intermittent wiper speed function is only active if the + after ignition is present and if the switch is in the
intermittent position.
The time delay between two wipes is 5 seconds, and this cannot be modified by the diagnostic tool.
When the rear intermittent speed function is activated, the rear intermittent speed relay is held by the UCH until the
park position is detected. When the intermittent speed time delay has elapsed, the relay is held again and the cycle
begins again.
Extended wiper time after washing
The UCH does not manage the rear washer pump command.
It only deals with the rear screen washer command input to provide wiping and extended wiping after washing.
This function is only active if + after ignition feed is present.
After the washer pump is activated, the first wiping is performed after a time delay of 750 ms.

Heated rear screen time delay
This output controls a diode relay which is external to the UCH, delivering the power to supply the heated rear
screen.
The de-icing time delay is activated by pressing the heated rear screen button located on the central console front
panel.
The heated rear screen time delay is deactivated:
– by pressing the button again if the time delay between activation and deactivation is less than 50 seconds,
– automatically if the time delay has elapsed,
– directly if there is a cut in the + after ignition feed or engine speed signal.
The minimum time delay between two presses of the button so that the command is taken into account, should not
be less than 200 ms.
