Threw a wierd code today
anyone ever had a P1626 code? Its theft deterent fuel enable signal not received. Never seen it or heard of it before. Heres what i found when i looked it up. Looking for some insight on which one of the reasons on the LS1s could would most likely cause it.
Also throwing a P1637 code which is Generator L terminal circuit wonder if that could be related too. Ive had this code before but it never threw the SES light on. The control module communicates with other modules using the Class 2 Serial Data circuit. The vehicle theft deterrent (VTD) body control module (BCM) sends a vehicle security password to the powertrain control module (PCM), via the Class 2 Serial Data circuit, after the BCM has sensed the proper operation of the ignition switch and lock, and determined that the switch and lock have not been tampered with. If this password matches the password stored in the PCM, fuel will be enabled. If the BCM does not send a password, or if the PCM does not receive it, the vehicle will not start, or it may start and stall. This will set a DTC P1626 in the PCM memory. If communication is lost after receiving the password, the VTD Passlock system will go into Fail Enable, set a U1192 in the PCM memory, and the engine will continue to run. This will allow the engine to restart on future ignition cycles but may set a DTC P1626 as the engine is started. If the battery is disconnected or the codes are cleared, the vehicle will lose its Fail Enable status and will not start until communication is re-established. Testing this system really requires a gm tech 2 scan tool so that you can watch certain paramters while clearing codes and attempting restarts. this problem could be caused by any of the following. • An open in the Class 2 Serial Data circuit between the PCM and the BCM • A short to ground • A short to voltage • Loose or damaged terminals at the DLC, PCM, or the BCM Read more: http://www.justanswer.com/questions/...#ixzz0blWirXTC |

thats the chip in the key. its either a dirty key or contacts in the ignition switch. the car will start and it will wait about 5-7 seconds looking for the signal and if it doesnt see it it will then cut the fuel. BUTTT the code can be set if wen you first crank it over and the signal is not present but finds it within the first few seconds it will stay running. if it were me id have the Vats tuned out from Don.

I dropped my dads key to his car in a punch bowl one time and it did that had to clean the key with contact cleaner to keep it from tossing the code
