Test S: The Powertrain Malfunction (Wrench) Indicator Is Never/Always On
PINPOINT TEST S: THE POWERTRAIN MALFUNCTION (WRENCH) INDICATOR IS NEVER/ALWAYS ONNormal Operation
The powertrain malfunction (wrench) indicator status information is transmitted to the instrument cluster (IC) over the high speed controller area network (HS-CAN) communication bus. The PCM sends a signal to the instrument cluster (IC) to illuminate the powertrain malfunction (wrench) indicator when an electronic throttle control system concern has been detected.
This pinpoint test is intended to diagnose the following:
- PCM
- Instrument cluster (IC)
