Component Inspection

Check ECTS resistance

IG "OFF" and disconnect ECTS connector.

Measure resistance between signal and ground terminals of ECTS connector after checking out the temperature of ECTS with scantool (Component Side)

Specification:

RESISTANCE SPECIFICATION

-40	48.14	40	1.15
-20	14.13~16.83	60	0.59
0	5.79	80	0.32
20	2.31~2.59

Is the measured resistance within specification?
YES
- 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
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.
