Service mode

Description of operation

Diagnosis of the GEM can be carried out using the Ford diagnostic unit. Furthermore, an integrated service mode enables testing of the input and output signals without the need for further tools.

To enable activation of service mode:

• switch off the ignition,
• switch off all other electrical consumers,
• apply the handbrake,
• Shift to neutral
• and close the doors.

Activating the service mode

NOTE: If the alarm is activated (in vehicles fitted with an anti-theft alarm system), service mode cannot be activated.

Proceed as follows to activate the service mode:

• OPERATE the switch of the heated rear window and HOLD IT THERE
• SWITCH ON the ignition.
• RELEASE the switch of the heated rear window

A signal sounds and the turn signal lamps come on to indicate that service mode has been successfully activated.

Inputs

SWITCH the windshield wiper switch to the "OFF" position to test the input signals. The following is a list of the switch signals to be tested, in no particular order:

• Windshield wiper stage I
• Windshield wiper stage II
• Windshield washer system
• Rear window wiper
• Rear window washer system
• Doors open/closed
• Remote control for central locking with double locking
• Hood open/closed (in vehicles equipped with an anti-theft alarm system)
• Tailgate open/closed
• A/C request signal
• Heated windscreen (if fitted)
• Parking brake
• Brake fluid level
• Cruise control system
• Autolamps
• Dipped beam
• Main beam
• Headlamp flasher
• Side lights
• Turn signals (right, left, hazard warning lights)
• Reversing lamp
• Liftgate release
• Folding liftgate release
• Ignition switch, terminal 15 (turn key to 0 position, then turn key to II position.)

An acoustic signal sounds and the turn signal lamps flash to indicate receipt of each input signal by the generic electronic module.

Test the windshield wiper "intermittent mode" stage input signal (only vehicles with adjustable intermittent mode):

The windshield wiper switch must be switched to "intermittent mode" in order to test the input signal.

The delay times of the input signals can then be tested by operating the rotary switch. Each change of the rotary switch position is indicated by an acoustic signal and illumination of the turn signals.

Output signals

SWITCH the wiper switch to the "Intermittent" position to test the output signals. PRESSING the heated rear window switch activates the output signals in the following order:

• Left-hand turn signal
• Right-hand turn signal
• Main beam
• Dipped beam
• Windshield wiper stage I
• Windshield wiper stage II
• Heated rear window
• Heater blower motor
• Headlamp washer system (vehicles with HID headlamps)
• Electric booster heater (if fitted)
• Autolamps (if fitted)
• Alarm horn (vehicles with alarm system)
• Rear window wiper
• Heated rear window relay

When the heated rear window switch is pressed again, the test of the relevant signal is terminated.

When the heated rear window switch is pressed once more, the test for the next signal in the list is started.

Ending the service mode

The GEM automatically ends service mode 20 seconds after the last input or at a driving speed of over 7km/h. However, service mode can be manually ended at any time by proceeding as follows:

• OPERATE the switch of the heated rear window and HOLD IT THERE
• Switch off the ignition.
• RELEASE the switch of the heated rear window

3 signals sound and the turn signal lamps illuminate to indicate that service mode has ended.

Resetting service mode

If, after completion of service mode, some functions do not operate or do not operate properly, check the following functions:

• Instrument cluster illumination, side marker lamps (side lights) and licence plate lamp in automatic headlamps mode
• Rear wiper
• Headlamp washer assembly
• Electric booster heater
• Alarm horn
• Heated windshield

If one or more of the listed functions is not OK, it's possible that the cause of the fault is due to not exiting service mode properly. To reactivate the functions correctly, perform the following steps:

1. Switch off the ignition.

2. SWITCH OFF the switch for the windscreen wash/wipe system

3. OPERATE the switch of the heated rear window and HOLD IT THERE

4. SWITCH ON the ignition.

5. RELEASE the heated rear window switch (an acoustic signal will sound if activation has been performed correctly)

6. SWITCH the windscreen wash/wipe switch to the "Intermittent wipe" position

7. OPERATE the heated rear window switch 6 times (the main beam headlamps switch on and off automatically)

8. SWITCH OFF the switch for the windscreen wash/wipe system

9. OPERATE the switch of the heated rear window and HOLD IT THERE

10. Switch off the ignition.

11. RELEASE the heated rear window switch (three acoustic signals will sound if activation has been performed correctly)

After completion of the work, check all the functions.
