Loss of KWP2000-ECU ID data
â–¶ How to fix
Replace the CUV unit (since ECU complete number can not be recovered/rewritten by SDP3).
What you'll see
No driver-visible symptom recorded.
System reaction
• COO red warning shown in ICL (since CUV is not sending the correct VIN) • Limited support in SDP3 (since the ECU complete number can not be identified)
Diagnostic depth
Detection
ECU identification data has been lost. Examples of lost data are ECU complete number and vehicle identification number.
Possible cause
System supply voltage (U30) was cut off while the ECU was writing to the file containing the ECU identification data.
