Electrical Issues

Is this a US or an EU Focus ? There could be Software updates for one of the modules. When testing your mechanic should try performing some of the 'Onboard' Computer test for the Body Electrical Systems. There are Input tests ( From the switches to the Computer) and out-put tests (from the Computer to the various out puts ( Lights, Wipers Washers ect) He has just got to activate the tests. GEM Service Mode The GEM features a service mode, that enables verification of the various inputs received by the GEM and output signals generated by the GEM. To enter service mode proceed as follows: 1. Press and hold the rear screen heater switch; the ignition switch is in position "0". 2. Turn the ignition switch to the position "II". 3. Release the rear screen heater switch. 4. Entry into service mode is confirmed by an acoustic signal; the direction indicator telltales on the instrument cluster flash once. 5. In order to test the input signals the windscreen wiper switch must be in the position "0". 6. The acoustic signal is emitted and the direction indicator telltales in the instrument cluster flash once when an input has been received by the GEM. The following input signals can be tested in any order: • Bonnet opening control switch • "Set/reset" - switch (only on vehicles without door modules) • "Lock/unlock" - switch (only on vehicles without door modules) • Tailgate opening control switch • Tailgate release switch (external) • Deactivator for the anti-theft alarm system • Lock door handle • Unlock door handle • Heated windscreen switch • Turn signal lamp switch • Hazard warning lights switch • Door contact switches • Intermittent wipe switch, rear screen wiper • "Normal wipe speed" switch • "Fast wipe speed" switch • Rear screen washer switch GEM Output Signals Test The GEM generated output signals are tested in a specific order while in "service mode". To test the GEM generated output signals, the windscreen wiper switch must be in the "Intermittent wipe" position. By toggling the rear screen heater switch, the status of the next output signal in the sequence is changed from activated or deactivated. The technician must observe whether the output being tested is physically working or not. Check all intermittent settings. When the setting is changed, an acoustic signal is emitted. The following GEM output signals are tested in this sequence: • Left-hand turn signal lamps • Right-hand turn signal lamps • Main beam • Dipped beam • Normal wipe speed • Fast wipe speed • Heated rear screen • Blower motor • Headlamp washer (if equipped) • Electric booster heater (if equipped) • Side lamp/number plate lights (only with automatic headlamps) • Alarm system horn • Rear screen wiper • Heated windscreen relay • Horn If the windscreen wiper switch position for the intermittent setting is not working, the output signals cannot be verified
