Check Oil Indicator (V6 Only)

The amber check oil indicator illuminates when the PCM reads the oil level switch and transmits a Class 2 message to instrument cluster indicating a low oil level condition. If the low oil level option is false, all Class 2 activity on the instrument cluster stops. The instrument cluster will not send out any request for the low oil level condition command and will not issue a low oil level condition report. If a loss of PCM Class 2 serial data occurs, the check oil indicator will not illuminate unless the indicator was illuminated when the event occurred.
