Component Inspection

Component Inspection

1. Check resistance of ETS Motor
(1) IG "OFF"
(2) Disconnect ETS motor & TPS connector.
(3) Measure resistance between terminal 5 and 8 of ETS motor & TPS connector. (Component Side)
A. Specification: Approx. 1.275 - 1.725 Ohms@ 23 °C (73.4 °F)




(4) Is the measured resistance within specifications ?
YES
1) Substitute with a known-good PCM and check for proper operation.
If the problem is corrected, replace PCM and then go to "Verification of Vehicle Repair" procedure.

CAUTION: 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
1) Substitute with a known-good ETC and check for proper operation.
If the problem is corrected, replace ETC and then go to "Verification of Vehicle Repair" procedure.

** Procedure of ETS Initialization
1. Erase the trouble codes on PCM
2. Turn the ignition key off and keep this condition until the main relay is turned off. (It will takes 10 secs.)
3. Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
