Electrical problem
1998 Acura CL 6 cyl Front Wheel Drive Automatic

I have a bad security module and replaced the module with a good used module. Tried to program the new module with my key fob for the car and it will not program. The doors will not lock unlock and the car will not start. The car did start with the old module. Can you program a alarm security module to work with your key fob for a new module?Also I tried to put back my old module that did work and it no longer works.I want to know if it is possible that I am programing the module wrong?
Do you
have the same problem?

Hello. Thanks for the donation. Much appreciated

first we need to check you are programming correctly? Let me know

REMOTE TRANSMITTER
NOTE:Procedures must be performed within the stated time limits. Four remote transmitters may be coded into system.

Turn ignition on. Within 1-4 seconds, press remote transmitter lock or unlock button while pointing transmitter toward keyless entry control unit. Turn ignition off (within 1-4 seconds) and go to next step.
To program another transmitter, repeat step 1). Four transmitters may be coded into keyless entry system. If more than 4 transmitters are coded, the first transmitter code will be erased. After all desired transmitters have been programmed, go to next step to verify system operation.
Within 15 seconds of programming final transmitter, press lock or unlock button. Verify that door locks operate and go to next step.
Check door lock operation using each transmitter. Turn ignition off and remove key. Remote transmitter codes are now stored in keyless entry system control unit. Verify door lock operation.

Hello. You will need to have the vehicle read to see if the immobolizer is giving out a fault code. Follow the steps below. Let me know !

DESCRIPTION
Immobilizer system is designed to disable vehicle when an incorrect ignition key is used. Immobilizer system consists of immobilizer control unit, 3 different coded keys, immobilizer receiver, immobilizer indicator light, starter cut relay, Powertrain Control Module (PCM), parking brake switch and transmission position switch.
A Black master key operates ignition and all locks, Gray valet key only operates ignition and door locks and Red learning key is only used to program replacement keys and will not start engine. If Red key is used to start engine all other keys will require reprogramming and engine will not start.
OPERATION
When ignition switch is turned to ON position, using a key with a transponder, immobilizer control unit energizes transponder through immobilizer receiver. A coded signal is sent back to immobilizer control unit from transponder. If signal is recognized by control unit, a start signal is sent to PCM and starter cut relay. Immobilizer indicator light will illuminate for a few seconds and go out. When ignition switch is turned off, immobilizer indicator light will flash for 5 seconds. If an unrecognized key (or other device) is used to turn ignition switch, engine starting circuit will be disabled. If immobilizer system does not recognize coded key, immobilizer indicator light will illuminate for about 2 seconds and then flash continuously.

SYSTEM TESTS
IMMOBILIZER SYSTEM TEST
NOTE:On vehicles equipped with immobilizer system, engine start time will be slightly longer than on vehicles without immobilizer system.

Ensure transmission selector is in Park position and brake pedal is fully depressed. Connect scan tool to DLC connector and check for Diagnostic Trouble Codes (DTCs). If scan tool displays DTC P1607, replace ECM/PCM. See ECM/PCM under REMOVAL & INSTALLATION. If DTC P1607 is not displayed, go to next step.
Turn ignition switch to ON position using known-good immobilizer key. Monitor indicator light in instrument cluster.. If indicator light flashes when ignition switch is turned on, go to next step. If indicator light does not flash when ignition switch is turned on, check for a faulty indicator light bulb, an open in Pink wire between indicator light and ECM/PCM or a faulty transponder (ignition key). After repair is complete, recheck system operation.
Disconnect 5-pin connector from immobilizer receiver. Use DVOM and measure voltage between ground and immobilizer receiver 5-pin connector terminal No. 1 (Yellow/Black wire). See Fig. 2. If battery voltage is indicated, go to next step. If battery voltage is not indicated, repair open in Yellow/Black wire between PGM-FI relay and immobilizer receiver. See WIRING DIAGRAMS.
Use DVOM to check continuity between ground and immobilizer receiver 5-pin connector terminal No. 4 (Black wire). If continuity is indicated, go to next step. If continuity is not indicated, repair open in Black wire between ground and immobilizer receiver.
Use DVOM to check continuity of Blue/Green wire between immobilizer receiver 5-pin connector terminal No. 2 and ECM/PCM terminal No. 25. If continuity is indicated, go to next step. If continuity is not indicated, repair open in Blue/Green wire between immobilizer receiver and ECM/PCM.
Use DVOM to check continuity of Orange/Blue wire between immobilizer receiver 5-pin connector terminal No. 3 and ECM/PCM terminal No. 13. If continuity is indicated, replace immobilizer receiver. See IMMOBILIZER RECEIVER under REMOVAL & INSTALLATION. If continuity is not indicated, repair open in Orange/Blue wire between immobilizer receiver and ECM/PCM.

AS I stated in my first question I can not program
my used security module to work with my original key. Is this because the security module is only for the original key and module and will not work with a module from another car even if it is the same module.

As shown in last post. Key and module are mated, the OLD key for your car. Is mated with the OLD module. You would need the keys mated to the used module you bought. Your OLD key will not be recognized by the NEW/USED module

OPERATION
When ignition switch is turned to ON position, using a key with a transponder, immobilizer control unit energizes transponder through immobilizer receiver. A coded signal is sent back to immobilizer control unit from transponder. If signal is recognized by control unit, a start signal is sent to PCM and starter cut relay. Immobilizer indicator light will illuminate for a few seconds and go out. When ignition switch is turned off, immobilizer indicator light will flash for 5 seconds.********** If an unrecognized key (or other device) is used to turn ignition switch, engine starting circuit will be disabled. If immobilizer system does not recognize coded key, immobilizer indicator light will illuminate for about 2 seconds and then flash continuously.***************

hope this helps

Hi,
I am greatly obliged by the team work. The work of the author is really great.
Did you know you can cancel your current auto insurance carrier and switch to a lower rate offer. And get your money back!
