3)

Is the measured resistance within specification ?

YES

▶ Go to "Check PCM" as follows.

NO

▶ Substitute with a known - good ECTS and check for proper operation. If the problem is corrected, replace
ECTS and go to "Verification of Vehicle Repair" procedure.

2.

Check PCM

1)

IG "OFF" and connect scantool.

2)

Connect probe to terminal 3 of ECTS harness connector.

3)

IG "ON" and ENG "OFF" and simulation Function on scantool.

4)

Simulate voltage at terminal 3 of ECTS harness connector.

5)

Does the signal value of ECT sensor change according to simulation voltage ?

YES

▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deteriora-
tion, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.

NO

▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.

NOTE

There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.

VERIFICATION OF VEHICLE REPAIR

EDB33B7C

After a repair, it is essential to verify that the fault has been corrected.

1.

Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.

2.

Using a Scantool, Clear the DTCs

3.

Operate the vehicle within conditions noted in the freeze frame data or enable conditions

4.

Monitor that all rediness test have been verified as " Complete "

5.

Are any DTCs present ?

YES

▶ Go to the applicable troubleshoooting procedure.

NO

▶ System is performing to specification at this time.
