Service Telltale

SERVICE TELLTALE
The SERVICE telltale is in the instrument cluster and informs the driver that a problem has occurred requiring the vehicle be taken in for service as soon as reasonably possible. This telltale is used for non-emission related failures, which without being serviced, could lead to component damage. As a bulb check. the lamp will come On for 2-3 seconds and then turn Off. If the telltale remains On, the self-diagnostics system has detected a fault. If the problem corrects itself or goes away, the telltale will turn Off 3 seconds after the ECM diagnostic test passes. A diagnostic trouble code will be stored in Freeze Frame/Failure Records.
