Component Inspection

Check TPS
1. IG "ON"
2. Monitor signal waveform of TPS by stepping on and off the accellerator padel on GDS.
Specification :













Fig.1) Normal waveform of TPS1 & TPS2 with no accel padal depressed under IG ON condition
Fig.2) Normal waveform of TPS1 & TPS2 with accel padal depressed under IG ON condition




3. Is the measured signal waveform O.K ?






** Procedure of ETS Initialization
A. Erase the trouble codes on ECM
B. Turn the ignition key off and keep this condition until the main relay is turned off.(It will take 10sec.)
C. Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
