DTC U0073:00 |
CAN system communication error (HS CAN) |
---|---|
DETECTION CONDITION
|
• If there is a malfunction in CAN bus communication line.
Diagnostic support note
• This is a continuous monitor (other).
• The MIL does not illuminate.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.
• The DTC is stored in the PCM memory.
|
FAIL-SAFE FUNCTION
|
• Inhibits the i-stop control and illuminates the i-stop warning light (amber).(PCM sends flash request to instrument cluster, however, i-stop warning light (amber) is illuminated by instrument cluster operation because flash request cannot be received on instrument cluster side)
|
POSSIBLE CAUSE
|
• CAN bus communication line malfunction
• PCM malfunction
