PINPOINT TEST V: THE ELECTRONIC THROTTLE CONTROL INDICATOR IS NEVER/ALWAYS ON

Test V1-V2:

Normal Operation
The instrument cluster receives the electronic throttle control status from the powertrain control module (PCM) over the standard corporate protocol (SCP) communication network, circuits 4-EG8 (GY/VT) and 5-EG8 (BU/WH). When a system concern is detected, the PCM sends the instrument cluster a command signal to turn the electronic throttle control indicator ON.

Possible Causes
- PCM
- instrument cluster
