Magnum V8-5.7L VIN H (2005)
Headlamp Control Module: Description and Operation
The Headlamp Leveling Module or HID Translator Module is the remote electronic sub-component of the headlamp leveling system. The HID translator
module is used to translate communication of the headlamps leveling system. The sensors communicate over a K-Line to the headlamp stepper motors,
then to the translator module. To enable the scan tool to read system inputs and outputs, and to retrieve Diagnostic Trouble Codes (DTC s), the translator
module must convert this K-Line data into Controller Area Network (CAN) data.
The HID translator module is located inside the right front engine compartment, just behind the headlamp unit. It is mounted to a stamped steel bracket
by one fastener and has one electrical connector that connects it to the wiring harness.
The system is designed to automatically level the vehicles headlamps, regardless of cargo or passenger loads or road conditions. When the vehicle is
loaded with passengers and/or cargo, as the ignition is turned to RUN, the system will look at the front and rear sensors and make an adjustment based
upon feedback from the sensor to see if it has approximately 27.5 degrees from its zero or neutral position. The headlamp stepper motor then adjusts the
headlamp up or down for proper headlamp aiming. The system is dynamic. The headlamp level will be adjusted while driving if required based on sensor
inputs.
NOTE: If the headlamp leveling module (HID translator module) or sensors are replaced, the system needs to be calibrated using a Scan Tool.
When in calibration mode, the key in the RUN position, the vehicle doors, trunk/liftgate, and hood must be closed. In addition, no one is seated in
vehicle, the vehicle may not be touched (bounced or bumped) until the calibration is complete. The headlamps must be ON to power the stepper motors.
The approximate calibration time is 12 - 15 seconds. The scan tool will display a status of calibration message. These being either still in progress,
passed,or failed.
If a system fault occurs, the translator module will store the Diagnostic Trouble Code (DTC) and enable it to be read using the scan tool and assist in
diagnosing the headlamp leveling system.
