Ford Focus 2006 turn indicator not working , can't find the fuse where is it.


Principles of Operation
When the multifunction switch is placed in the LH or RH TURN positions, a voltage signal from the GEM is routed to ground. When the GEM detects the multifunction switch in the LH or RH TURN position, the GEM supplies voltage to the appropriate turn lamps in a flashing manner.
When the hazard warning switch is pressed, a voltage signal from the GEM is routed to ground. When the GEM detects a request for the hazard lamps, the GEM supplies voltage to all the turn signal lamps in a flashing manner. When operating correctly, the hazard lamps flash approximately 80 times per minute.

Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect the following for obvious signs of mechanical or electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Hazard switch
  • Multifunction switch
  • Central junction box (CJB) fuse 32 (15A)
  • Bulb(s)
  • Circuitry
  • Generic electronic module (GEM)

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
    • check that the program card is correctly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
    • ISO circuit fault; all electronic units no communication/not equipped, refer to Section 418-00 .
    • No response/not equipped for GEM, refer to Section 419-10 .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the GEM.
  1. If the DTCs retrieved are related to the concern, go to the Generic Electronic Module (GEM) Diagnostic Trouble Code (DTC) Index.
  1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

I've got a 2006 Ford Focus, and recently the rear left indicator has stopped working (I have changed the bulb but the new one(s) don't work either) with the other indicators flashing double quick.


The turn signal lamps on your vehicle are controlled by the GEM - generic electronic module . Have the car checked for DTC'S - diagnostic trouble codes . Auto part stores can not check these code's , need a factory or professional type scan tool . These codes (if any) would point to the problem area . They flash faster because the GEM see's a problem and it's a warning indicator something is wrong , they made it like that so you go to the dealer . Principles of Operation
When the multifunction switch is placed in the LH or RH TURN positions, a voltage signal from the GEM is routed to ground. When the GEM detects the multifunction switch in the LH or RH TURN position, the GEM supplies voltage to the appropriate turn lamps in a flashing manner.
When the hazard warning switch is pressed, a voltage signal from the GEM is routed to ground.

All my lights work on my 2005 ford focus except the lower brake lights and turn signals. all fuses are good.


Do you know anything about automotive electronics ?
Stoplamps
The stoplamps are part of the rear lamp assembly. When the brake pedal is applied, the stoplamp switch supplies voltage to the generic electronic module (GEM) and the high mounted stoplamp. The GEM then supplies voltage to the rear lamps.

Turn Signal Lamps and Hazard Warning Lamps
The turn signal lamps and hazard warning lamps system consists of:
  • Hazard switch
  • Multifunction switch
  • GEM
  • Turn signal lamps
When the multifunction switch is placed in the LH or RH turn positions, a voltage signal from the GEM is routed to ground. When the GEM detects the multifunction switch in the LH or RH turn position, the GEM supplies voltage to the appropriate turn lamps in a flashing manner. When operating correctly, the turn lamps flash approximately 80 times per minute.
When the hazard warning switch (located in the upper part of the center console) is switched on, a voltage signal from the GEM is routed to ground. When the GEM detects that the hazard switch is switched on, the GEM supplies voltage to all the turn signal lamps in a flashing manner. When operating correctly, the hazard lamps flash approximately 80 times per minute.

We have a 2001 Ford Escape with a small problem. The remote key fob locks the doors and unlocks the doors but the lights don't flash anymore when you lock the door. The horn also won't honk after hitting...


I think you need to reprogram the module, you deleted the horn chirp and light flash confirmation. he dealer can reprogram for you.

Principles of Operation
Power Door Locks
The generic electronic module (GEM) controls the power door lock and keyless entry system. Lock and unlock operation is achieved through the use of internal relays in the GEM. The relays are all door lock, all door unlock and driver door unlock. The normal path of the relays is to ground.
Pressing the door lock control switch to lock or unlock sends a ground signal to the GEM. The same GEM pin is used for unlock and lock input. The unlock signal is a direct connection to ground. The lock signal is altered by an internal resistor in the door lock control switch. This varied resistance identifies lock or unlock command to the GEM.
The door locks can also be controlled by the door key cylinder switches. For the liftgate door lock switch, turning the key to lock or unlock sends a ground signal to the GEM. The GEM will then ground the all door lock or all door unlock relay supplying voltage to the actuators. Turning the driver door key cylinder to the lock position sends a ground signal to the GEM. The GEM will then ground the all door lock relay supplying voltage to the actuators. Turning the driver door key cylinder to unlock sends a ground signal to GEM. The GEM will ground the driver door unlock relay and supply voltage to only the driver door actuator. If a second unlock ground is received within three seconds of the first, the GEM will ground the all door unlock relay supplying voltage to the passenger door actuators (if 2-stage unlock is equipped).
Keyless Entry
The keyless entry remote transmitter sends a signal that is received by the GEM internal antenna. Depending on the signal received, the GEM module will ground the appropriate internal relay and lock all doors or unlock the driver door. If the unlock signal is received again within three seconds of the first unlock, the GEM will ground the internal all door unlock relay unlocking all doors. The lock and unlock relay output to the actuators is controlled by the GEM, the same as power door lock operation from the control switch.
If the signal received is for the panic button, the GEM will cycle ground to the park lamp relay coil and horn relay coil. The park lamps and horn will continue to cycle until the panic button is pressed again or the ignition switch is turned to the RUN position, or after the timer expires.

I need an instruction manual for my RCA Clock Radio Model RP3750A. Can't turn off the alarm - want radio to come on with the radio and not the alarm.


There are three buttons under the heading "Dual Wake", WK1, Cancel, WK2. The WK buttons refer to the two wake time settings you can have. Press Cancel and then WKx. That will turn off the alarm. If you press WKx more than once, it will cycle through small symbols on the bottom of the screen with the number x in front of them. First symbol means it will have a sound alarm for alarm x, second symbol means it will have a radio alarm and the third symbol means it will play the CD to alarm. You set the time for alarm with the slide switch at the back of the unit, selecting WK1 for alarm 1 and WK2 for alarm 2. You can have both alarms active at once, or either one singly.
