    Relays chatter from only 2 thing, low voltage or a poor ground. Have you tested the Body Control Module??

How do you enable a range rover engine when key battery is flat


There is a sequence of left and right turns of the key in the driver's door that will reset your bECM (Rovers brain) if the following have been tried.
1. Replace batteries in remote and 're-sync by depressing lock button on remote while physically turning and locking the door. Don't release button until locked and key removed. Repeat for unlock button.
2. Disconnect negative/earth cable from battery. While disconnected open driver's door, turn ignition to position 2, return to battery leaving driver's door open and reconnect the negative cable. Proceed to ignition. Turn off completely. Close all doors and hood and attempt starting.
Should both of these methods fail, run a search here on fixya for "engine disabled Range Rover P38" This will take you to step by step instructions on resetting the bECM which I opened this post with. It has been covered many times here, including by myself, no reason to post it again.
Good Luck!

2008 honda accord air will not work ,has freon ,relay works but compressor will not kick on.


#1 top A/C post here ever. bravo that.
this is caused by by the AC brain.
(location varies by year, and country)
A/C brain discrete, cira 90s
to after 2007 , they moved the brain, now pure software inside
the ECU or BCM , on most cars.
it really dont matter much where it is until you get to back probe the bugger. right?
so , here is the reasons for A/C clutch dead.

1:clutch bad, apply 12v to it see if it works (wires discon, please)
do so for on 1second, so as not damage system.
check for coil ohms near 1ohm. at clutch.
infinity is bad coil.
OR do :
1b" 12v to coil AC on? any volt meter works. 11 to 15v typical.
13.3 to 14.7 running engine typical.
yes, clutch dead.
2: 12v not at coil of clutch bad relay.
3: relay coil not energized.
3a: power to relay not on coil, if yes, bad relay .
3b: relay coil dead. no power. the brain has it shut down!

4: the brain, stops the AC for all these reasons
simple answer , inputs wrong.
full answer:
a: too low freon pressure, in truth or sensor fibbing
b: too high freon pressure, same, reasons.
c: ENGINE over load, (pulling trailer or going WOT )
d: engine overheat. (ecu say so or AC has its own sensor saying so, RTM.
e: Evap core (the cold core in dash) has frozen over to a ice brick. (a freeze sensor is there) caused by stuck open expansion valve. in core.
f: no power to AC brain, 90s cars. or missing ground,
g: AC not on, or brain can not see fan going, usual the is just
the 12vdc to fan missing. or the wire fell off.

some cars have all this, my 96 does.
on newer cars the ECU can shut the AC down for many reasons.
most are related to safety to the driver, or Compressor.
for what reasons, only the FSM answers that , and varies
by year, engine type, model and country sold.
if in usa , you didnt say. then alldata dot com has these facts
and more , under section called HVAC.

The brain will not allow you to burn up the compressor or worse.
it tries very hard at that. even as old as 1991 cars. (some)
today all.

Remote door locks keep engaging and disengaging until battery goes dead.


There is either a short in the receiver logic board for the remote, its wires or a relay chattering in the fuse box...Pull the door lock relay in the fuse box to prevent the battery from being drained and begin troubleshooting.

Power door locks do not work unless the ignition switch is on, radio and dome lights also do not work.


look for another fuse box in or under dash. still sounds like you have a blown fuse. look in owners manual for all fuse box locations,including underhood electrial center. good luck.

My keyless door remote can't lock or unlock car doors despite the fact that the remote is functioning. The car respond to the remote signal but no effect on door locks.


Seems like the remote and the receiving unit stopped working on same channel.
1) Make sure you have the radio security code at hand, because it will trip after disconnecting battery. 2) Disconnect battery to reset alarm computer for 5 minutes or so, and reconnect it. 3) insert key in ignition. 4) press on the remote and don't let go. 5) turn the ignition to the accesories/ radio position. at this point you should see a "key" icon flashing on the dashboard. 6) after 10 seconds or so, let go of the remote. Repeat the operation, just to make sure. Also, do the same sequence for the spare remote, because it will lose the frequency as well.

Car won't start.Theft light blinks,clicking sound under hood and thumping like horn wants to go off.Seems like it's stuck in anti theft mode


anti theft light should blink every few seconds.

try disconnecting the battery for 15 minutes.

Anti-Theft-Perimeter The perimeter anti-theft system consists of the following components:
  • anti-theft indicator (THEFT)
  • remote anti-theft personality (RAP) module
  • hood switch
  • keyless entry remote transmitter
  • deck lid ajar switch
NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.
Up to four keyless entry remote transmitters (15K601) can be programmed at one time.
The keyless entry remote transmitters :
  • Are programmable.
  • Must be set at the same time.
  • House four buttons.
  • House three buttons (Mexico Anti-Theft System only).
Programming
Refer to Section 501-14B.
Inputs and Outputs
The remote anti-theft personality (RAP) module receives input from the following components for anti-theft operation:
  • Hood switch.
  • Deck lid ajar switch.
  • Keyless entry remote transmitter.
  • Power door lock switches (LH and RH).
  • Door courtesy input.
The RAP module distributes output to the following for the anti-theft system:
  • Power door unlock relay.
  • Power door lock relay.
  • Liftgate unlock relay (Wagon)
  • Park lamps relay.
  • HORN relay.
  • Dome lamp.
  • THEFT indicator.
  • Deck lid release.
Arming
The anti-theft system can be armed if:
  • The ignition switch is in the OFF position.
  • The panic alarm is off.
  • All doors are closed.
NOTE: If a door is open, the anti-theft system is prearmed and waiting for all the doors to be closed. The THEFT indicator will remain illuminated for up to 30 minutes waiting for all the doors to be closed. If a door remains open after 30 minutes, the THEFT indicator will turn off and the system will return to a disarmed state. After all doors are closed and the 30 second prearm (continuous THEFT indicator illumination) is complete, the system is armed.
NOTE: If the theft LED does not flash after 30 seconds, check the LED FLASH PID to see if the feature is enabled.
The anti-theft system will be armed when the lock button on the keyless entry remote transmitter is pressed, all doors are closed and 30 seconds have elapsed.
When the system is armed, the THEFT indicator will flash quickly until the system is triggered or disarmed.
Disarming
NOTE: Using a key in a door lock cylinder to unlock is not a valid method of disarming the anti-theft system.
Untriggered System
NOTE: If the driver arms the system and remains in the vehicle, an untriggered system can be disarmed by turning the ignition switch to the ON position.
An untriggered alarm system can be disarmed by pressing the unlock button on the keyless entry remote transmitter.
Triggered System
NOTE: If the hood or trunk are open when the system is armed, it must be closed and opened again before it can trigger an alarm.
An armed anti-theft system can be triggered by the following conditions:
The deck lid door, liftgate, hood or any door is opened using a key, inside door handle, hood release, etc.
  • The keyless entry remote transmitter can activate a panic alarm which is similar to the anti-theft alarm, but does not cause the THEFT indicator to flash.
A triggered alarm system can be disarmed by:
  • Pressing the unlock or panic button on the keyless entry remote transmitter.
  • Turning the ignition switch to the ON position.
Alarm State When Battery Power Is Cycled
When the RAP module is supplied power the first time at the vehicle assembly plant, the system will be in the disarmed state. The RAP module will remember whether it is armed, disarmed or triggered in its non-volatile memory. When the battery positive cable is removed and then reconnected, the system will return to the state it was in just before the battery was disconnected. If the system is in any prearm state, then the system will return to a disarmed state when the battery is disconnected and then reconnected.

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.
