Here’s a step-by-step guide on how to bypass the security system in your 1998 Chevy truck: Warning: Bypassing the security system may compromise your vehicle’s security, and it should only be done at your own risk. It’s highly recommended to consult with a professional mechanic or contact Chevrolet customer support for assistance.

2017年8月7日 · The security light will flash and stay on. After 10 minutes shut off the key and repeat. Do this 3 times and it will learn the 2.2 K resistor as the new resistance for the ignition switch.

2014年10月29日 · Basically, the Passlock 2 security system disables the fuel supply if the computer doesn't recognize the keyed ignition lock cylinder is turning legitimately. The turning cylinder has 2 small magnets and as it turns past a coil - more or less - creates a hall effect.

2014年6月2日 · This is the only way to permanently bypass the security without paying out the A$$ to have the whole 9 yards tuned out of the ecm.

2011年12月11日 · The Security Telltale will light up indicating that the Passlock System is inoperative. Once the security telltale has been on for at least 5 seconds the vehicle can be turned off and then remotely started.

2022年8月12日 · Start the engine (the vehicle has now learned the Sensor Data Code and/or password). If your security light should stay on after the vehicle is running, cut the yellow wire in B2 and tape it off. IMPORTANT: If your car still does not start, please follow the troubleshooting directions for Passlock 1/2 Systems before contacting our support team.

2024年4月18日 · So I have an odd issue with the notoroius anti-theft system on a '98 Tahoe. Here's a rundown of everything; 1. Fuel Pump replaced a second time after a shade tree mechanic misdiagnosed the crank/no start issue and did an improper pump replacement (disconnected filler hoses, lines, electrical, etc.) 2.

2007年12月13日 · I have a 99 suburban that will occationally not start due to the factory security system. The dealership said they'll need to replace the ignition switch, key, and a couple of other things (not the security module though according to the computer) to make it work.

2015年10月4日 · The remote start system engages the resistor that is used as a bypass for a certain period of time to fool the PCM that the key is being used to crank the truck. That being said, if you spend a few bucks on a PCM tune, you pick up some performance or MPG and you can have them turn passkey off in the programming....
