Focus ZX5 L4-2.0L DOHC VIN 3 (2002)
off by its own limit switch.
Rear window washer with wiper function
If the rear window washer switch is operated, the washer pump and the rear window wiper are switched on. If the rear window washer switch is
released, the washer pump is immediately switched off. The run-on time for the rear wiper is (4.0 s ± 1.0 s). The duration of the ground pulse for the
rear wiper relay is transmitted by the CTM and amounts to 0.6 s ± 0.2 s.
Front windscreen washer with wiper function
If the front windscreen washer switch is operated, the washer pump and the front windscreen wiper are switched on. If the front windscreen washer
switch is released, the washer pump is immediately switched off. The front windscreen wiper motor performs another 2-3 wiper cycles and is then
switched off by the CTM by means of the front wiper relay or the limit switch.
Heated Rear Window
To switch on the heated rear window, the heated rear window switch must be pressed for at least 30 ms. The heated rear window will then be switched
on for 10 min ± 2 min via the heated rear window relay. During these 10 mins the heated rear window can be switched off either by pressing the
heated rear window switch again, or by turning off the ignition. Under these conditions, the CTM sends a ground signal to the heated rear window
relay, which in turn switches the heated rear window. If the ignition switch in turned to "Start" while the heated rear window is switched on, then the
heater will be temporarily switched off during this time.
Heated windscreen
To switch on the heated windscreen, the heated windscreen switch must be pressed for at least 30 ms. The heated windscreen will then be switched on
for 4 min ± 1 min via the heated windscreen relay. During these 4 mins the heated windscreen can be switched off either by pressing the heated
windscreen switch again, or by turning off the ignition. The heated windscreen can only be activated when the generator is supplying voltage, i.e.
when the engine is on. Under these conditions, the CTM sends a ground signal to the heated windscreen relay, which in turn switches the heated
windscreen.
Entry Illumination
For vehicles without remote control: The interior light will be switched on when one of the doors is opened, regardless of the ignition key position, as
long as the vehicle is unlocked and the interior light switch is in the "Delay" position. Within 0.5 s, the CTM regulates the lights from off to full
brightness. When the doors are closed, there are two options. The interior light remains at full brightness for 20 s and then dims to darkness within 5 s.
If the ignition is switched on after closing the doors, then the light will be dimmed out within 2 s.
For vehicles with remote control: If the vehicle is unlocked using remote control, then the ATWS/double locking system operates the CTM. This
regulates the lights from darkness to full brightness within 0.5 s, before a door is opened. If the vehicle is locked using the remote control, then the
interior light is dimmed out within 2 s.
If the ignition is switched off before the exterior lighting, then the interior lights come on for 20 s at full brightness before dimming out within 5 s. The
same thing happens when the exterior lighting is switched off while the ignition is on, and the ignition then is switched off within 20 s.
30 mins after switching off the ignition, the interior lighting is switched off by the CTM by means of the power saving relay if one of the doors is open
and the interior lighting switch is in "Delay" position.
The luggage compartment light is not controlled by the CTM.
Power saving relay
30 mins after switching off the ignition, the CTM turns off the power saving relay and switches to Off mode. This mode applies until one of the
following occurs: Unlocking by remote control, opening a door or the tailgate, or switching the ignition key to "Radio" or "Ignition" position. The
power saving relay is then re-activated by the CTM and supplies current back to the components that it switched off in the vehicle (interior lighting,
electric mirror adjustment mechanism).
Acoustic Signal
The following modules request acoustic signals from the CTM: Trip computer module, anti-theft warning system/double locking module and airbag
module. Since the requesting modules do not have an acoustic warning system, they send a ground pulse to the corresponding input on the CTM, at
which point the CTM in turn sends a defined acoustic signal. The CTM determines which acoustic signal has to be transmitted from the length of the
input pulse. The airbag module sends a ground signal to the CTM if the warning lamp in the instrument cluster bezel is activated by the CTM, but is
faulty. Otherwise, the airbag module sends a ground signal to the CTM each time the ignition is switched on, in order to maintain the contact to the
module connector. The trip computer module sends a ground signal to the CTM if the fuel level drops below a certain level, or to confirm each time
one of the trip computer module switches is pressed.
Lights-on Warning Chime Unit
If the driver's door is opened when the ignition is switched off and the parking light, dipped beam or main beam are still on, then the warning buzzer
sounds (integrated in the CTM). The buzzer stops when the exterior lighting is switched off, the driver's door is closed or the power saving relay
switches off after 30 mins.
Safety Belt Warning
If the ignition is switched on and the safety belt is not fastened, then the warning buzzer sounds for 4 to 8 s and the belt buckle warning lamp in the
