Clear Dtcs - Xtool PS90 User Manual

PS90 Diagnosis System
Tip: In the process of diagnosis, if the device shows "System is OK" or "No Trouble
Code", it indicates that the ECU has not detected a fault in any of the circuits that it
monitors. If there is a fault which is not being recorded it may be that the fault is
with a part of the system not under the control of ECU, such as a mechanical system
fault. It is also possible that the signal of a system sensor may be incorrect but still
within the ECUs stored limits, this can be verified in Live Data.
