TROUBLE DIAGNOSIS

1.

INSPECTION START

1.

Check service records for any recent repairs that may indicate a related incident.

2.

Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to
MA-8, “PERIODIC MAINTENANCE (FOR EUROPE)”.

3.

Open engine hood and check the following:

–

Harness connectors for improper connections

–

Vacuum hoses for splits, kinks, or improper connections

–

Wiring for improper connections, pinches, or cuts

4.

Start engine and warm it up to the normal operating tempera-
ture.

>> GO TO 2.

2.

PREPARATION FOR CHECKING IDLE SPEED

With CONSULT-II

PREPARATION

1.

ECM is located behind the glove box. For this inspection,
remove glove box.

2.

Remove ECM harness protector.

3.

When disconnecting ECM harness connector, loosen it with
levers as far as they will go as shown in the figure.

4.

Connect a break-out box (SST) and Y-cable adapter (SST)
between the ECM and ECM harness connector.

●

Use extreme care not to touch 2 pins at one time.

●

Data is for comparison and may not be exact.

ECM INSPECTION TABLE

Remarks: Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
