PINPOINT TEST E: THE CHARGING SYSTEM WARNING INDICATOR IS OFF WITH THE IGNITION SWITCH IN THE RUN POSITION AND THE ENGINE OFF

E1:

Normal Operation
The GEN MON circuit 8-BA25 (WH/RD) carries 0.1 volt with the key in the ON position (C102a connected) and the engine not running. This turns the charging system warning indicator on. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system.

Possible Causes
- generator C102a unplugged
- generator
- instrument cluster
- powertrain control module (PCM)
