Conditions for Setting the DTC
WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The module first writes information to a cell, or address, in the EEPROM. The module then reads the information and compares the information to what was sent to the address. If they do not match after 3 consecutive attempts, the module sets this DTC.
