Ford Historic Self-Test Routines
6
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).
Select STAR Test Mode from the Ford
Function List and press ENTER
Follow the instructions on the tool screen
to access DTCs from the PCM. Pressing
ENTER begins test.
The TEST/HOLD parameter indicates
the state of the STI (Self-Test Input). The
ENTER key toggles this state from TEST
to HOLD.
With the STI in the TEST state, the
self-test begins. The STO (Self-Test Output) parameter flashes either a HIGH
or LOW. A beep will accompany each LOW flash. Write down the 2– digit or 3
– digit code for reference.
✓
Disregard the blink which may occur when ignition key is turned ON.
Depending on the vehicle being tested, determines if a three digit or two
digit code used. If required, refer to the vehicle service manual for
applicable code structure.
❒ A digit consists of consecutive LOW flashes or beep — count the
number of LOWs for the digit
❒ A short HIGH (short pause) occurs between digits.
❒ A long HIGH (long pause) occurs between codes.
❒ There is no flash for the digit 0 (zero).
