High Altitude Warning
Cause:
If the battery voltage falls below a minimum level, these memories are erased and the TCM determines there is a malfunction in the power circuit. At the next engine start, the TCM will illuminate the MIL and set the DTC. The engine and transmission system do not operate as expected. A problem has been detected in the engine’s electrical system, including the charging and starting system that monitors and controls the engine starting system and the 12V battery charging system.
