*1:lThis is Quick Reference of ªDIAGNOSTIC TROUBLE CONFIRMATION PROCEDUREº.
Details are described in each specific TROUBLE DIAGNOSIS.
*2:
lThe ªOVERALL FUNCTION CHECKº is a simplified and effective way to inspect a component or circuit.
In some cases, the ªOVERALL FUNCTION CHECKº is used rather than a ªDIAGNOSTIC TROUBLE CONFIRMATION PRO-
CEDUREº.
When no DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE is available, the ªNGº result of the OVERALL FUNCTION
CHECK can be considered to mean the same as a malfunction item detection.
lDuring an ªNGº OVERALL FUNCTION CHECK, the malfunction item might not be confirmed.lThis is Quick Reference of ªOVERALL FUNCTION CHECKº.
Details are described in each specific TROUBLE DIAGNOSIS.
*3: CONSULT-II may not detect, but self-diagnostic results are available with MI.
*4: Imaginary sensor, which produces secondary engine revolution signal using needle lift sensor pulse.
*5: The atmospheric pressure sensor is located inside the ECM and is not replaceable.

ECM INSPECTION TABLE
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
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.
