PINPOINT TEST S: THE ELECTRONIC THROTTLE CONTROL (ETC) WARNING INDICATOR IS NEVER ON

S1-S4:

Normal Operation
The instrument cluster receives the ETC status from the powertrain control module (PCM), and the transmission control module (TCM) over the communication network. When a system concern is detected, the PCM or the TCM sets a diagnostic trouble code (DTC) and sends the instrument cluster a command signal to illuminate the ETC warning indicator.

Possible Causes
- PCM
- TCM
- instrument cluster
