Pinpoint Test 11

PINPOINT TEST 11: THE MALFUNCTION INDICATOR LAMP (MIL) INDICATOR IS NEVER/ALWAYS ON

Normal Operation
The instrument cluster receives the MIL status from the powertrain control module (PCM) over the high speed controller area network (HS-CAN) communication bus. When a fault condition exists in the PCM, a DTC is set in the PCM and a message is sent to the instrument cluster to illuminate the MIL warning indicator. The instrument cluster sets a continuous DTC if the PCM data is missing for more than 5 seconds or if invalid data is received and the instrument cluster illuminates the MIL.

This pinpoint test is intended to diagnose the following:
- PCM
- Instrument cluster
