Diagnosis Description
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go to "sleep mode", potentially causing a discharged battery and a no-start condition.
FUNCTION
CONSULT can display each diagnostic item using the diagnostic test modes shown as per the following:
| Diagnostic test mode | Function |
|---|---|
| ECU Identification | The part number stored in the control unit can be read. |
| Self Diagnostic Result | Self-diagnostic results and freeze frame data can be read and erased quickly. |
| Data Monitor | Input/Output data in the EPS control unit can be read. |
