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

S1-S3:

Normal Operation
The instrument cluster receives the electronic throttle control (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 DTC and sends the instrument cluster a command signal to illuminate the ETC warning indicator.

Possible Causes
- PCM
- instrument cluster
