Jarrad MotorsCastertonJarrad MotorsCastertonExamples of how Jarrad Motors Casterton diagnoses vehicle faults properly — testing first, then repairing the actual cause.
Book DiagnosticsCall 03 5581 1142These examples show the type of diagnostic work we carry out for local drivers, work vehicles and breakdown follow-up repairs. Fault codes and symptoms are only the starting point — the important part is proving the cause before replacing parts.
Problem: The vehicle would randomly not start, and previous attempts to fix it had not solved the issue.
Diagnosis: Electrical testing traced the fault to the starter control circuit rather than simply guessing at a battery or starter motor.
Fix: The wiring fault was repaired and the starting system was retested to confirm reliable operation.
Problem: The engine light was on and the vehicle had reduced power.
Diagnosis: Scan tool fault codes were used as a guide, then live data testing confirmed the issue before parts were replaced.
Fix: The faulty component was replaced and the system was checked again to make sure the fault was resolved.
Problem: The battery kept going flat even after charging.
Diagnosis: A parasitic draw test found a module staying active when the vehicle should have been asleep.
Fix: The draw was identified and resolved, preventing repeat flat battery failures.
Problem: The vehicle had multiple warning codes and would not start correctly.
Diagnosis: Wiring diagrams, fuse checks and scan data were used to narrow the issue down instead of clearing codes and hoping.
Fix: The circuit fault was corrected, then the remaining airbag connection fault was repaired and verified.
