In later vehicles the VATS system was renamed to PassKey I.

If the key reading is still incorrect, the system will go into FAIL ENABLE mode allowing you to drive the vehicle, but the SECURITY light will stay on. It may be different for earlier years, or the new GM Delta and Kappa platforms. Try cleaning the pellet and restart after the 4-min time out. You may have to do it a few times to get it to work, but I've done several relearns on 00+ J-bodies, and they all work the first time out thus far.

The SECURITY light or equivelent should now be off.ĥ) Turn the key to the off position and remove it (just to make sure) wait 10 seconds, then start the car Code U1064 Chevrolet Description Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation.

AFAIK, the jbody never had an encoded key. They were updated to class2 electrical in 2000.īut on topic, I'm not sure what the original poster is hoping to accomplish by removing or disabling security system. its earliest incarnation is the 2.2 OHV, and in 1998 was updated to the 2200 version (very small changes and different induction set up). from Guangdong Provincial Animal Center and the calculation method was as. the 2001 and previous 2.2 liter is the LN2 (more commonly referred to as the OHV or 2200). I wasnt really sure how this would turn out, so I went with what Ive got. The ecotec wasn't available in the Jbody until 2002. HPT does not support the EcoTec 4 cylinder at all at this time.
