ECM
*1: Accelerator pedal position sensor 2 signal and throttle
position sensor 2 signal are converted by ECM inter-
nally. Thus, they differ from ECM terminals voltage signal.
*2: Before measuring the terminal voltage, confir m that the battery is fully charged. Refer to PG-4, "How to
Handle Battery".
*3: The item is indicated, but not used.
