ACTIVE COMMAND MODES PROCEDURE

1. Connect the M-MDS to the DLC-2.

2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.



When using the IDS (laptop PC)

1. Select "DataLogger".

2. Select "Modules".

3. Select "IC".



When using the PDS (Pocket PC)

1. Select "Module Tests".

2. Select "IC".

3. Select "DataLogger".

NOTE:



The PID data screen function is used for monitoring the calculated
value of input/output signals in the module. Therefore, if the
monitored value of the output parts is not within the specification, it
is necessary to inspect the monitored value of input parts
corresponding to the applicable output part control. In addition,
because the system does not display an output part malfunction as
an abnormality in the monitored value, it is necessary to inspect the
output parts individually.



If the operation of output parts cannot be verified after the active command mode inspection is
performed, this could indicate the possibility of an open or short circuit, sticking, or operation
malfunction in the output parts.
