EC-26
[QR (WITH EURO-OBD)]
PRECAUTIONS
● After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.
● When measuring ECM signals with a circuit tester, connect
a break-out box (SST) and Y-cable adapter (SST) between
the ECM and ECM harness connector.
● When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
● Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.
● Do not operate fuel pump when there is no fuel in lines.
● Tighten fuel hose clamps to the specified torque.
