Master Troubleshooting & Diagnostics Matrix

Error Code / IndicatorSymptom / MeaningStep-by-Step DIY FixSuggested Actions
N/A
Power supply or charging current failure
Possible Cause: Poor wire connections or short circuit resulting from unsatisfactory cable attachment
Check the 12V supply line, inspect the plug fuse, and ensure connections are secure. If the issue remains unresolved, contact an authorised service agent.DIY Check / Tech Fallback
N/A
Damage to product or components
Possible Cause: Mechanical impacts, overvoltages, or unauthorised modifications
Have repairs carried out by a specialist or contact an authorised workshop.Professional Intervention Required
N/A
Cable burn, airbag triggered, electronic control units damaged, or electrical functions failing (indicators, brake lights, horn, ignition, lights)
Possible Cause: Inadequate wiring connections leading to a short circuit
Check the 12V supply line, inspect connections, and ensure correct cable cross-sections are used according to the manual specifications. If the issue remains unresolved, contact an authorised workshop.DIY Check / Tech Fallback

Check the 12V supply line, inspect the connections, and ensure secure cable cross-sections. If faults persist, contact an authorised workshop.DIY Check / Tech Fallback
N/A
Batteries are not charging sufficiently or air conditioner cuts out during operation.
Possible Cause: Insufficient electrical connections or voltage drop across standard vehicle wiring due to high current draw.
Check the 12V / 24V supply line, inspect the high-intensity fuses, and ensure cable cross-sections match the specified requirements. If the issue remains unresolved, contact an authorised service agent.DIY Check / Tech Fallback
N/A
Air conditioner does not start or shuts down unexpectedly.
Possible Cause: Undervoltage detected by the load current distributor or incorrect D+ signal from the alternator.
