On-demand self-test
- When the on-demand self test is implemented, the current malfunctions of the selected module can be read out. (See DTC INSPECTION .)
- There are two types of the ODDTC self-tests; KOEO (key ON, ignition off) self-test while the ignition is switched ON and engine is stopped, and KOER (key ON, ignition running) self-test while idling and the vehicle is stopped.
- The DTCs which can be read out by the on-demand self test are not stored in the module, but with the M-MDS, the CMDTCs are read out automatically after the ODDTCs read out, and both of the results are displayed.
