Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | The system fails to start | The battery voltage is low - either the charger has failed or no voltage is reaching it at all. | Recharge the battery. | DIY Safe |
N/A | The red battery lamp comes on | The battery voltage is low - either the charger has failed or no voltage is reaching it. If the red lamp stays lit continuously, the system shuts itself off for 4 minutes. | Recharge the battery. | DIY Safe |
N/A | The support jacks won't extend down even with the pump running | Could be a low oil level or air in the system, a faulty valve or pump, or a broken electrical connection between the control system and the valve. | Look for oil leaks and address them - clean, repair, or replace parts as needed - then check the cabling for voltage drop and repair if you find any. | DIY Safe |
N/A | The system shows a 'SLOPE TOO STEEP' warning | The vehicle is tilted beyond its safe leaning limit - typically because the caravan's front end is sitting too high. | Wind the jockey wheel down to bring the front end lower. | DIY Safe |
