Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure EBS010RU
1. CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect throttle control motor relay.
3. Check voltage between throttle control motor relay terminals 2, 5
and ground.
