PINPOINT TEST AH: THE ELECTRONIC THROTTLE CONTROL INDICATOR IS NEVER ON

Test AH1:

Test AH1-AH2:

Normal Operation
The instrument cluster receives the electronic throttle control status from the powertrain control module (PCM) over the CAN, using circuits 3125 (RD/YE) and 3126 (TN/YE). 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
