multiple warning lamps on while driving, TRAC CTRL, High Ex.Temp.,
amber warning "yield sign", SERVICE Park Brake, BRAKE PRESSURE,
BRAKE FLUID, ABS. Message center has "Electrical Fault*".
Intermittent problem, may go for days or weeks with no problem,
then it comes and stays awhile. Last time it happened on me, I was roadtesting and the lights came on when I signaled left for lane change. Any help would be appreciated. |

just finished going through all the connections in the battery box, nothing obvious, just cleaned and re-wrapped a bunch of connections.
Warning lamps are off, going to drive it and see. |

| Along with those 3 fuse check the connectors. Look for discolored pins and melted plastic. Follow that harness out the battery box along the left frame rail and up the left side of the engine. Again pull the connectors apart and look at them. Next check the relays on the center of the fire wall. Unplug them and look at the connector for burnt pins or melted plastic. |

| Had one on a 2010 CE that the 3 fuse harness was bad. If you ohmed it out, it would show good, but twist it a bit and it would lose connection on the TCM. |
