Parasitic Current Draw Diagnostics
Battery discharge while parked can result from excessive consumption after the vehicle is switched off. Parasitic draw diagnosis starts with battery condition and the circumstances in which the problem occurs. We account for electronic modules entering sleep mode, since a reading taken immediately after shutdown can be misleading. We then trace the circuit or consumer that remains active. The result identifies the fault area and a basis for repair; diagnosis does not automatically mean replacing a control unit.
Symptoms
- The battery loses charge while the vehicle is parked.
- An electrical consumer remains active after shutdown.
What's included
- Review discharge conditions and assess battery state.
- Measure consumption while accounting for sleep mode.
- Systematically trace the circuit with excessive consumption.
- Record findings and agree on a corrective approach.
