DTC Confirmation Procedure

EBS00LZ1

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.

 WITH CONSULT-II

1.

Start engine and warm it up to normal operating temperature.

2.

Turn ignition switch “OFF” and wait at least 10 seconds.

3.

Turn ignition switch “ON”.

4.

Select “DATA MONITOR” mode with CONSULT-II.

5.

Restart engine and let it idle for 2 minutes.

6.

If 1st trip DTC is detected, go to 

EC-217, "Diagnostic Procedure"

.

 WITH GST

1.

Start engine and warm it up to normal operating temperature.

2.

Turn ignition switch “OFF” and wait at least 10 seconds.

3.

Restart engine and let it idle for 2 minutes.

4.

Turn ignition switch “OFF” and wait at least 10 seconds.

5.

Restart engine and let it idle for 2 minutes.

6.

Select “MODE 3” with GST.

7.

If DTC is detected, go to 

EC-217, "Diagnostic Procedure"

 .

●

When using GST, “DTC Confirmation Procedure” should be performed twice as much as when
using CONSULT-II because GST cannot display MODE 7 (1st trip DTC) concerning this diagnosis.
Therefore, using CONSULT-II is recommended.

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 dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
