Is the measured signal waveform O.K ?

▶ 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 automaticallydetected and memorized by PCM.Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others.

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

(After replacing ETC, do initialization of ETC as follows)

※ 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 take 10sec.)

3. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
