Sebring LX Coupe V6-3.0L VIN H (2002)
Connector
CIRCUIT OPERATION
-
If the headlight switch signal from the column switch turns on, the front-ECU makes the headlights illuminate. Whenever the headlights illuminate,
the low-beam lights illuminate due to the headlight dimmer switch automatic resetting function.
-
If the SWS communication line is defective, the low-beam headlights will illuminate by using other signal line (headlight back-up circuit).
TECHNICAL DESCRIPTION (COMMENT)
The column switch or the front-ECU may be defective.
NOTE: If only one of the headlights does not illuminate, the light bulb may be burned out or the wiring harness between the light and the front-ECU
may be defective. In this case, check the circuit by referring to Headlight. See: Lighting and Horns/Headlamp
