DTC 051 Or 052: Reprogram Cluster Or Cluster Malfunction: Description

Calibrations for instrument cluster are stored in Electrically Erasable Programmable Read Only Memory (EEPROM). When ignition is first turned on, instrument cluster performs internal tests on EEPROM and can determine the integrity of EEPROM's nonvolatile memory. DTC 51 indicates that EEPROM is either not programmed or an internal malfunction exists. DTC 052 indicates that EEPROM is partially programmed.
