Generic Electronic Module (GEM)
Refer to Wiring Diagrams Section 419-10, for
schematic and connector information.
Special Tool(s) / General Equipment
Terminal Probe Kit
418-S035Digital multimeter
Ford approved diagnostic tool
Description of operation
A diagnosis of the generic electronic module (GEM)
can be performed with the Ford approved
diagnostic tool. 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
• Close the doors.
Activate service mode
Proceed as follows to activate service mode:
• PRESS and HOLD the switch of the heated rear
window
• SWITCH ON the ignition.
• RELEASE the switch of the heated rear window
A signal sounds and the turn signal lamps
illuminate to indicate that service mode has been
successfully activated.
NOTE: If the alarm is armed (in vehicles fitted with
an anti-theft alarm system), service mode cannot
be activated.
Input signals
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: • Turn signals (right, left, hazard warning lights)
• Windshield wiper stage I
• Windshield wiper stage II
• Windshield washer system
• Rear window wiper
• Rear window washer system
• Doors open/closed
• Door key cylinder set/reset switch
• Remote control for central locking with double
locking
• Hood up/down (in vehicles fitted with anti-theft alarm system)
• Tailgate open/closed
• Mini liftgate open/closed
• Manual A/C request signal
• Manual AUX heater request signal
• Heated windshield (if fitted)
• Parking brake
• Brake fluid level
• Cruise control system
• Autolamps
• Dipped beam
• Main beam
• Headlamp flasher
• Side lights
• Reversing lamp
• Tailgate release
• Mini liftgate release
• Interior scanning system
• 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. G1055084en

Component Tests
Hydraulic Leak Check
NOTE: There is a common clutch and brake fluid
reservoir, therefore it is possible that a clutch leak
can lead to reduction in the reservoir level.
It is possible that all evidence of fluid leakage may
have washed off if the vehicle has been operated
in rain or snow, as brake fluid is water-soluble.
Refill the system, bleed then apply the brakes
several times. Examine the system to verify that
the reservoir fluid level is actually dropping. Locate
and repair the external leak. If the fluid level drops
and no external leak can be found, check for a
brake master cylinder bore end seal leak.
Brake System Check
Brake Pedal Reserve Check
Where a low brake pedal or the feel of a
bottomed-out condition exists, check for brake
pedal reserve.
1. Operate the engine at idle with the transaxle in the NEUTRAL position.
2. Apply the brake pedal lightly three or four times.
3. Allow 15 seconds for the vacuum to replenish the brake booster.
NOTE: This increased resistance may feel like
something has bottomed out.
4. Apply the brake pedal until it stops moving downward or an increased resistance to the
pedal travel occurs. 5. Hold the brake pedal in the applied position and
raise the engine speed to approximately 2000
rpm.
NOTE: The additional movement of the brake pedal
is the result of the increased engine manifold
vacuum which exerts more force on the brake
booster during engine rundown. This means that
additional stroke is available in the brake master
cylinder and the brake system is not bottoming out.
6. Release the accelerator pedal and observe that the brake pedal moves downward as the engine
returns to idle speed.
Brake Booster Functional Test
Inspect all hoses and connections. All unused
vacuum connectors should be capped. Hoses and
their connections should be correctly secured and
in good condition with no holes and no collapsed
areas. Inspect the check valve on the brake booster
for damage.
Brake Booster Operation Check
1. Check the hydraulic brake system for leaks orlow fluid.
2. With the transaxle in the NEUTRAL position, stop the engine and apply the parking brake.
Apply the brake pedal several times to exhaust
all the vacuum in the system.
3. With the engine turned off and the vacuum in the system exhausted, apply the brake pedal
and hold it down. Start the engine. If the vacuum
system is operating, the brake pedal will tend
to move downward under constant foot
pressure. If no motion is felt, the vacuum
booster system is not functioning.
