No CEL

 

Pulled this new code, not sure what to make of it...

Headlight issues:

 

HBA codes are for the High Beam Adjustment of the Litronics servo motors.  You either have an electrical issue (loose connector, frayed wiring, etc.) with one or both lights, one or more weak servo motors that move the lights, or the headlight control module itself is on the way out.

 

From the OEM manual:

 

Fault code 1 Motor circuit, left

This fault is stored in the following cases: 1. Short circuit to ground or open circuit in the circuit between control module and servomotor for HBA, left, terminals 1,2, 3, 4 2. Servomotor for HBA, left, is faulty 3. The control module is faulty

 

Elimination: Switch off ignition - Pull plug off the control module - Pull plug off the servomotor for HBA - Check for open circuit in the supply leads to the servomotor for HBA, terminals 1, 2, 3, 4 Ohmmeter display: < 5 Ohms - Check for short to B+ in the supply leads to the servomotor for HBA Ohmmeter connected to terminals 1, 2, 3, and 4; measure resistance to ground Ohmmeter display: Infinite Ohms - Check for short circuits between the supply leads.

If no fault is detected in the wires, replace the servomotor for HBA. Also check the plug on the wiring harness side and replace if necessary.

 

Fault code 2 Motor circuit, right

This fault is stored in the following cases: 1. Short circuit to ground or open circuit in the circuit between control module and servomotorfor HBA, right, terminals 5, 6, 7, 8 2. Servomotor for HBA, right, is faulty 3. The control module is faulty

 

Elimination: - Switch off ignition - Pull plug off the control module - Pull plug off the servomotor for HBA - Check for open circuit in the supply leads to the servomotor for HBA, right, terminals 5, 6, 7, 8 Ohmmeter display: < 5 Ohms -  Check for short to B+ in the supply leads to the servomotor for HBA Ohmmeter connected to terminals 5, 6, 7, and 8; measure resistance to ground Ohmmeter display: Infinite Ohms

- Check for short circuits between the leads. If no fault is detected in the wires, replace the servomotor for HBA.
