Posted to Technical Tips Forum on 1/19/2012 22 Replies

Occasionally when you program a G.M. module, you may have a failure. At this point an E-code will be displayed. Usually there is no definition of this failure other than the code. Here is a list of the most common failure codes.

E4398 - no Calibration Data - the calibration data is not loaded onto G.M.'s server - you need to cotact Techline for a VCI number or a calibration update.

E4399 or E4403 - Severe Error - loss of communication between the programming devive and module - ck connections and battery voltage. Programming communication speed may be too fast for the module.

E4413 or E4414 - non recognized calibrations or calibrations marked with an * - restart programming and select "Replace and Reprogram"

E4404 or E4494 - loss of communication brtween the programming device and Techline

E4491 or E4423 - Programming Failed - incompatibility between the software/calibrations and the module - contact Techline
