 IPDM E/R Symptom Inspection contents Possible cause
Diagnosis mode Description
Ecu Identification Allows confirmation of IPDM E/R part number.
Self Diagnostic Result Displays the diagnosis results judged by IPDM E/R.
Data Monitor Displays the real-time input/output data from IPDM E/R input/output data.
Active Test IPDM E/R can provide a drive signal to electronic components to check their operations.
CAN Diag Support Monitor The results of transmit/receive diagnosis of CAN communication can be read.
