Question about Mazda CX-7

1 Answer

MAZDA CX-7 2008. Conventional key with remote for doors and a chip for the anti-theft system. It happened twice in similar conditions. Car was in a busy parking lot for a hot summer day. Came back to the car at the end of the afternoon. Unlocking the doors with the remote was OK. All equipments were OK and running. But the car refused to start. No crank. Looked like the anti-theft system was not recognising the key (Sorry, I did not notice the flashing ligths). I had the car towed to the nearest dealer but it was closed. Even after dropping the car that evening, the car refused to start. I came back the next morning and tried to start before speaking with the mechanics. The car started easily rigth away. As said, it happened one month later, in the same conditions (public parking lot, hot summer day, towing, restarting the next morning). I heard that it could be related to other cars' remotes keys. What's going on ?

If it would have been related to other cars key's it would happen every time you would park in a crowded place. No, it must be related to the heat - the antitheft module heats so much that its processor stops working. What you can do is to change the location of the module or insulate it somehow. But it could also be a bad connection that when the dash heats up it gets loose - you need to check the wiring in the dash.

How does the ignition interlock work on the mazda mpv 2003 ? I can't start the car without the remote control : Simply turning the key will not even crank, does nothing.


Often, you need to press the unlock button on the remote twice. First press unlocks the door and second press disables the immobiliser and allows the vehicle to start. The key alone will not start the vehicle.

Alternatively, when the key is in the ignition - press the remote unlock again.

The remote acts as an immobiliser device. The reason your car won't start on the key is probably because the system won't allow any key in the ignition - it is preventing theft of the vehicle. Once the unlock button on the remote is pressed the system then recognises that key is the legitimate one for the vehicle and the disables the immobiliser and allows you to start the car

I have a 2002 mazda 626 when i get in to start it the lillle light that looks like a car with a key in it flashes then gos of


The car and key looking light are immoblizer or security system warning. If it illuminates briefely with the other dash warning lights when key is turned on and then goes out it is just performing a bulb check. It light remains illuminated, flashes, or vehicle will not start with either conditions of the light then your security system has been activated. The system is looking at a computer chip that is built into your key. If chip signal does not match one that has been programmed to start the vehicle then it will not start for anti theft purposes. Any new keys need to be programed with an external computer to start the vehicle. Interference with key signal can occur if on a key ring with other keys from other cars or same car that has a chip. Remove from keychain if using a key that has worked in the past.

Reset anti theft system


it has gone into theft mode. you will need to have the system rest. it makes it so the parts are useless. when you take the battery off for any reason you need to have the key in the ignition on number 2 then off to 0. leave key in and you now have 30 seconds to take of the battery. just taking off the battery with out doing this can activate the systerm.

89 firebird anti theft code won't let car start


If code 53 involves the PASS system for your car, the chip in the key has failed, or the sensor in the lock cylinder, or the control module.
The anti-theft system disables the starter and the fuel injectors. You could bypass those circuits to get the car started.

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.

This is from Ken on CarPros:
Here is the way to reset the security system.

https://www.2carpros.com/articles/how-to-reset-a-security-system

Here is the systems descriptions

There are 2 security system, namely anti-theft and immobilizer.

Here are the 2 systems.

DESCRIPTION & OPERATION
Anti-theft system is controlled by Body Control Module (BCM). BCM receives signals from hood switch, trunk switch, door switches and Local Control Modules (LCMs). There are 5 LCMs located throughout vehicle.

To set anti-theft system in armed mode, remove ignition key, close all doors, trunk and hood. Lock doors using key or remote controller. The SECURITY light will illuminate for 30 seconds, then flash in 2.4 second intervals, indicating system is in armed mode.

To cancel armed mode, unlock and open any door or trunk lid using key or remote controller. SECURITY light will flash every second, indicating system is disarmed.

Alarm will activate (horn sounds, headlights flash and starter circuit is disabled) if any of the following conditions occur while system is in armed mode:

Engine hood or trunk lid is opened using the hood or trunk lid release.
Door(s) is unlocked without key or remote controller.
Tampering with any door/trunk lid key cylinders.
To deactivate anti-theft system, unlock door or trunk using key or remote controller.

If it is the immobilizer that is preventing the engine from being started, ensure you have the correct key and the transponder is intact. Quite often keys are dropped and if it breaks open, the internals would scatter all over. When this occurs, there is a tendency for the transponder to be lost.

Please let us know happens so it will help others.

Best, Ken
I hope that helps you out!

Replaced the alternator, now anti theft won't disable


The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:
  • The antenna for the keyless entry remote transmitter.
  • 26 circuit connector (C256).
  • 22 circuit connector (C257).
In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
Prearming and Arming the System
The system can be armed if:
  • The ignition is OFF.
  • The PANIC alarm is OFF.
  • All doors are closed.
There are two ways to prearm the system:
  • Press the LOCK button on the transmitter.
  • Open a door, press the power door lock button and close the door.
After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:
  1. Pressing the UNLOCK button on the transmitter.
  1. Placing a key in the door and turning to UNLOCK.
  1. Turning the key to RUN or ACC.
The anti-theft alarm can be triggered by the following conditions:
  • The ignition cylinder is damaged with or without the RAP being armed.
  • A door is opened without disarming the armed RAP module.
The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:
  1. Pressing the UNLOCK or PANIC button on the transmitter.
  1. Putting a key in the door and unlocking the door.
  1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).

Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
