CODE DESCRIPTION
Battery disconnected or first installation.

A battery backed RAM is used to maintain some learned values. When the battery is disconnected, this memory is lost. When the battery is connected, this memory loss is detected by the controller. The code is set and the learned values are initialized to known constants. This results in the re-initialization of some parameters.

PROBABLE CAUSE
- Battery disconnected (After securely connecting the battery, use the scan tool to erase the DTC.)
