CAUTION:
- You may want to check which unit is malfunctioning according to Freeze Frame Data. "Electrical" > "IC Service Function" > "Freeze Frame Data".This function is supported on IDS, not PDS.
- DTC U2023 may not be cleared during engine starting even if DTC clearing is done using the M-MDS. When clearing DTC U2023, execute with the ignition switch in the ON position (Engine off).
