I changed the battery but the horn keep blowing when i hook the new battery up


Sounds like (no pun) it is the alarm system going off. After installing the battery try using the key fob to deactivate the system.

How to reset anti theif alarm


There are different alarm systems, not same for all kind of cars. You should explain, by the way, what do you mean by "resetting" an alarm.
If you mean that you have an activated alarm and you want to deactivate it some can be deactivated by turning the start key.
Then, some have a hidden button you may press
Finally, some CAN'T be deactivated, only by remote.
You only can turn off the sound removing battery cable then deactivate physically the system and to do this you should know alarm installation techniques.
To change alarm coding you need and electronic tecnician.

Failsafe engine mode


You might try to have your battery tested. The Anti-theft system reacts to low battery voltage and automatically reduces the Voltage to the starter so it will not turn over or turn over fast enough to start; thereby defeating thieves.

Failsafe usually is an extreme heat sensor mode which deactivates some of the cylinders so the engine exhausts excess heat through the exhaust valve. This is why top speed is limited and power is reduced. The deactivated cylinders act like air compressors, they have no fuel charge, and thereby draw air into the cylinder and expel heated air.

99 ford f150 4wd won't engage, clicks but does not engage


Without knowing how the 4X4 works you don't have much chance of finding the problem , (tapping on stuff ) ? There is an electronic control module that makes this system work . Could have DTC'S - diagnostic trouble code's stored in the (GEM)
Transfer Case -Electronic Shift on the Fly (ESOF) Operation The electronic shift on the fly (ESOF) system is an electronic shift 4x4 system that allows the operator to choose between two different 4x4 modes as well as 2-wheel drive. The operator can switch between 2WD and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L range, the vehicle speed must be less than 5 km/h (3 mph), the brake pedal depressed, and the transmission must be in NEUTRAL.
The transfer case is equipped with an electromagnetic clutch which is located inside the case. This clutch is used to spin up the front driveline when shifting from 2WD to 4H mode at speed. When the control switch on the instrument panel is turned, the generic electronic module (GEM) recognizes that a shift has been requested and activates the electromagnetic clutch and the relays which power the transfer case shift motor. When the shift motor reaches the desired position, as determined by the contact plate position inputs to the GEM, power to the shift relays and motors will be removed. When the transfer case front and rear output shafts are synchronized, the spring loaded lockup collar mechanically engages the mainshaft hub to the drive sprocket. Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated.
Shifts between 2WD and 4H can be made at any speed up to 88 km/h (55 mph). Listed below are the inputs and outputs needed by the GEM to execute a change between any of these modes.
Feature Inputs:
  • 4WD mode switch (various resistances; go to Table 1).
  • Contact plate position inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
Feature Outputs:
  • 4x4 shift motor relay outputs (go to Table 2).
  • Transfer case clutch relay (grounded when relay is activated, open circuit when relay is deactivated).
  • 4x2/4x4 vacuum solenoid (grounded when activated, open circuit when deactivated).
  • Cluster indicators (ground when activated, open circuit when deactivated).
When shifting into or out of 4L, the GEM requires that the vehicle speed be less than 5 km/h (3 mph), the brake is applied, and the transmission is in NEUTRAL.

Feature Inputs:
  • 4WD Mode Switch (various resistances; go to Table 1).
  • Contact Plate Position Inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
  • Output Speed Shaft (OSS) Sensor (Sinusoid Signal: 0.7V-20V, 2.2 Hz/mph).
  • Brake Input (battery voltage when brake is depressed, open circuit when not activated).
  • Transmission Range Sensor (grounded when transmission is in NEUTRAL, open circuit otherwise).
  • Start/Clutch Depressed Input (go to Table 3).
Feature Outputs:
  • 4x4 Shift Motor Relay Outputs (go to Table 2).
  • 4x2/4x4 Vacuum Solenoid (grounded when activated, open circuit when deactivated).
  • Cluster Indicators (grounded when activated, open circuit when deactivated).

Door panel lights wont turn off


push the door switches in by hand and see if the lights go out. Here's some diagnostic info:

Vehicles may be equipped with either a generic electronic module (GEM) or a central timer module (CTM) depending on vehicle options.
  • Vehicles with 4-wheel drive or the power group option will be equipped with a GEM.
  • Vehicles with 2-wheel drive and no power group option will be equipped with a CTM.
Courtesy Lamps The GEM and the CTM illuminate the interior lamps when any door is open or ajar. The interior lamps are: the interior lamp, the cargo lamp and the door courtesy lamp. The courtesy lamps will shut off when:
  • The doors are closed and the illuminated entry (GEM only) feature is not active.
  • The vehicle speed is greater than 15 mph (24 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 10 mph (16 km/h) and a new door open warning lamp switch signal is received (GEM only).
The system inputs to the GEM/CTM are as follows:
  • The door open warning lamp switches. (Grounded when door is ajar; an open circuit when the door is closed.)
  • The vehicle speed sensor (VSS) input. (Sinusoid Wave: 0.7V-20V, 2.2 Hz/MPH [1.37 Hz/km/h] [GEM only].)
The system output to the GEM/CTM is as follows:
  • The interior lamp relay coil output. (Grounded when activated; open circuit when deactivated.)
Interior Lamp Relay The GEM and the CTM control the interior lamps and illuminated entry function with the interior lamp relay.
The relay is activated by applying ground to the relay coil through GEM C267-15, and is deactivated by removing the ground signal.
Panel Dimmer Switch The panel dimmer switch is integrated into the headlamp switch and controls the interior lamps by activating the interior lamp relay.
Illuminated Entry (GEM Only) The GEM illuminates the interior lamps when an unlock signal is received from the remote anti-theft personality (RAP) module. The illuminated entry feature will be canceled when any of the following conditions are met:
  • 25 seconds have elapsed since the illuminated entry feature was activated and the courtesy lamp feature is not activated.
  • The GEM receives a request from the RAP module (remote transmitter lock button pressed) and the courtesy lamp feature is not activated.
  • The ignition is in the RUN or START position and the courtesy lamp feature is not activated.
The illuminated entry inputs are:
  • RAP illuminated entry request. (Grounded pulse of varying length.)
  • Ignition switch in the RUN position. (Battery voltage on both the RUN and RUN/ACC inputs.)
The illuminated entry outputs are:
  • Interior lamp relay coil output. (Grounded when activated; an open circuit when deactivated.)
RAP Module The RAP module sends a signal to the GEM on the illuminated entry request circuit to indicate a request to turn the illuminated entry feature on or off. Circuit 1013 (BR/LG) is normally sent 12 volts by the GEM. The RAP module shorts this circuit to ground with a pulse of either of the following lengths:
  • 200 ms pulse from RAP receiver assembly requests illuminated entry ON (unlock button pressed).
  • 300 ms pulse from RAP receiver assembly requests illuminated entry OFF (lock button pressed).
GEM Sleep Mode The GEM and the CTM sleep mode deactivate all outputs to conserve battery power. Sleep mode is entered when the ignition has not entered the RUN or ACC position and 45 minutes has elapsed since the last wake-up input was received. In this mode, GEM current consumption is reduced to 5.0 mA or less. During sleep mode the GEM monitors the following wake-up inputs:
  • Both front door open warning lamp switches.
  • Ignition switch in the key-in, ACC and RUN position.
  • RAP illuminated entry request.
The GEM sleep mode outputs are:
  • None. (All circuits are deactivated during sleep mode.)
If a change in any of the above inputs occur while the GEM is asleep, the GEM will wake up and monitor all of its inputs and have the ability to activate any of its outputs.
The following components are under the control of the battery saver relay:
  • Interior lamp.
  • Engine compartment lamp.
  • Glove compartment lamp.
  • Panel dimmer switch.
  • Interior lamp relay.
The battery saver relay becomes active (relay coil is energized) when the GEM is in the awake mode, and is deactivated (relay coil is de-energized) in the sleep mode. The battery saver will remain active until the ignition switch is removed from the ACC or RUN position and 45 minutes have passed since the last active input was received (see sleep mode inputs). At that time, the relay will be deactivated and power to the above circuits will terminate.
The battery saver inputs are the GEM sleep mode inputs.
The battery saver output is the battery saver relay.
Inspection and Verification — GEM/CTM
  1. The interior lighting system is a generic electronic module (GEM)/central timer module (CTM) controlled system. Refer to Section 419-10 for additional information regarding GEM/CTM diagnostic strategies.
  1. Verify the customer concern by operating the interior lamps.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Switch(es)
  • Fuse(s) 14 (15A), 15 (5A), 4 (5A), 8(5A), and 103 (50A).
  • Wiring harness
  • Loose or corroded connector(s)
  • Circuitry open/shorted
  • Bulb(s)

  1. If the concern remains after the inspection, connect the New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel, and select the vehicle to be tested from the NGS menu. If the NGS 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.

Security system not working as it used to


i read this on the subaru tech bulletin page
i had the same problem - apparently i had inadvertently put the system into "valet" mode
to get back to normal, unlock with remote - open drivers door - hold down the unlock button on your remote for 2-3 sec - the flashing light will go out and your system should be back to normal
it's too bad the manual doesn't supply information about activating and deactivating "valet" mode
good luck

Deadbolt mode


Deadbolt mode must be activated and deactivated using the key in the driver's door. Insert the key and turn (I believe) all they way to the right to activate and all the way to the left to deactivate

The D3 code on my 2007 honda odyssey is on what is the problem


Hi!
This is not a code. Instead it is an indication that you are running the van in "overdrive off" mode.

Your van is equiped with a 5 speed automatic transmission. By running in overdrive off you are essentially running in 3rd gear, out of 5 gears. This will cause your van to run at a much higher engine speed, while not going very fast at all and consuming a lot more gas than normal.

You can deactivate this mode by:
1) start the van
2) Press the break pedal
3) Shift to 'D' (drive mode)
4) press the little button that is located on the left side of the shifter, under the shifter button.

If the light does not go out after pressing this button, you may need to take the van to your Honda dealership. Your van should still be under warranty as it is a 2007 model.

Good luck!
