Battery No Charge Message

The IPC monitors the Alternator L-terminal input on Connector C1 terminal "A9." If the Alternator is not charging, ground is applied to the L-terminal. If the Alternator is charging, the L-terminal will be at ignition voltage. The IPC uses this input to detect DTC B1911 (Alternator "L" terminal Problem). If it is detected, the "BATTERY NO CHARGE" message will be displayed. This will occur whenever the L-terminal input is "LOW" and the engine has been running over 400 RPM for more than 2 seconds.
