Due to the different systems and the diversity of display messages (system errors/ warnings and instructions), it is all the more important that these be correctly interpreted so that unnecessary diagnostic work is avoided.
e.g. the message (Tire Pressure Monitor currently unavailable)
Message is due to:
- Interference
- Overvoltage/undervoltage
No defect - no repair necessary
System errors are recorded with fault entries, which must always be processed in accordance with the fault tree.
Please note that actual values may only be used for diagnosis when this is explicitly permitted.
