HBA Diagnosis
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 Ohm
- 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 Infinity Ohm
- 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.
