Coded for failed PCM

Good evening.

First, what code led you to a bad PCM?

Did you use a new PCM and have it flashed to your car?

The ten minute relearn is not a bypass but you are teaching the key the password for the anti theft. You do that procedure three times for the key to learn the password.

In this security system the key does not have a transponder built in and does not learn anything. The system learns a specific footprint of the ignition lock rotating. You can add or replace as many keys as you like without any programming but a change of the PCM does require the thirty minute relearn, done in the proper sequence. The Instrument cluster acts as the security control module.
This system does have common issues with the lock sensor and related wires having problems. There is a method to bypass the sensor but the rest of the system would still be operational.

PASS-LOCK SENSOR BYPASS:
Look for the black wire and the yellow wire from the pass-lock sensor in the column, cut the wires and you can solder in a 2.2K (2200 ohm) resistor connecting them together and then attempt to start the car. It will stall do not turn the ignition off. Leave the ignition on for ten minutes or until the theft light goes out. Turn the key off for ten seconds then attempt to start the car. If it now runs you have been successful. If it does not you either made a mistake or there are other problems besides the ignition lock cylinder.

This relearn process is used when the PCM has not been changed. In your case it has to be repeated three times in succession, even if you do the bypass.

The first thing I would do is have the PCM programmed to your vehicle. Any shop with an advanced scan tool can do this for you.

The cost is about $100.00.

I understand but it is the only way.
