![]() ![]() ![]() still no switch lights nor does the 4x4 work. Maybe a P0300 or perceived stall code, too. After 1 or 2 CKP failures the codes P0335/6 and/or P0385/6 set. The car retains all power and usually restarts easily. chamged tcscm with dorman preprogrammed, plug and plat tcscm. The classic CKP failure shuts off the engine (only) during a slow warmup cycle or a coast-down to stop for a turn or signal. U1000 CLASS 2 SERIAL COMMUNICATION PROBLEM CODEWhen more than one critical parameter does not have an identification number associated with it, the code will only set once. 2002 gmc envoy with 4x4 service light on, no 4x4 switch light operation, 4x4 inop. When a module does not associate an identification number with at least one critical parameter within 5 seconds of starting data communication, DTC U1000 or U1255 is set. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. These Node Alive messages are used for State of Health monitoring. When a module receives a message for a critical operating parameter, the module records the identification number of the module that sent the message. anyone have any insight to what these could mean thanks ahead of time. All modules are showing a Class 2 communication problem, t. Restraints U1016 - Loss of Class 2 Communication with VCM (History) (Immature) HUD U1000 - Class 2 Communication Malfunction (History) (Immature) i did a search on google and came up with some air pump problems with CTSs and other random stuff. These modules monitor the link for serial data. Operating information and commands are exchanged among the modules. I have a 2006 Cadillac CTS 2.8L DM, both needles are dead (GAS-TEMP).
