Data monitor (SPEC)
Input/Output of the specification for Basic fuel schedule, AFM, A/F feedback control value and the
other data monitor items can be read.
Active test
Diagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also
shifts some parameters in a specified range.
DTC confirmation
The status of system monitoring tests and the self-diagnosis status/result can be confirmed.
ECM part number
