STAR Test Mode (EEC-IV, MECS and MCU Vehicles)
The STAR Test Mode can be used to retrieve DTCs from the PCM or other
STAR (Self-Test Automatic Readout) compatible controllers installed in the
vehicle. STAR Test Mode functions largely the same way and serves the same
purpose as running KOEO and KOER tests. It is generally used as a last resort
to check for DTCs in systems which may not be covered by KOEO and KOER
testing (i.e. - Computer Ride Control suspension systems).
