Bypass tcm module 2003 chevrolet truck

You can't. It has an anti-theft device. The days of boosting a car with a couple of wires ended in the 1980s! You have to fix the problem, not find a way around it.

Hello,

The key has the chip for the anti-theft--may not be the anti-theft.
TDC/Firing Order/fuel/spark/compression/timing chain alignment (dots)
TPS (Throttle position sensor) - Bypass by holding gas pedal down and starting.

Hope this helps--

there is one wyre you can cut coming from the computer check itrenet taht will disable antitheft everything else will work properly that will let you no if it is the anti theft

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.

You probably can't.
If the anti-theft module is in the cluster, you would need the correct key chip for the car the cluster came out of.
You might be able to bypass the passkey system by running a wire to the fuel pump relay and other components.
You may need a shop manual to find the circuits.

Hi,
Firstly what is the problem as to why you need to disconnect the anti-theft system? Also you can't just disconnect the Anti-theft as it is incorporated within the starting and ignition system.The only way it can be bypassed is through a Ford Dealer who will have the equipment and coding to disable it.

http://vatspasslockpasskeysecurityhelp.yolasite.com/ Go to that link. You are exactly right. The engine swap has confused the anti theft security system. It can disable the starter and/or the injectors/fuel. There are ways to bypass these systems. You can do it yourself too. Ive personally done dozens of these bypasses, and they work great. Good luck

U can bypass it (called the VATS system) but not fully disable it, what is done mimics the key code to fool the VATS module into sending a OK to start signal to the fuel injection computer (called the ECM). go to the web link below for instructions on the bypass.

On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.
