Diagnostic Mode 08 - Request Control of on-Board System, Test or Component






Diagnostic Mode 08 - Request Control of On-Board System, Test or Component

Diagnostic Mode 08 is used to control the operation of an on-board system, test or component. A Mode 8 service can be used to turn on-board system ON or OFF, or to cycle an on-board system, test or component on or off for a specific period of time. The service can also be used to request system status or to report test results.

Diagnostic Mode 08 is not supported for 2012 Model Year due to a change in design of the Leak Detection Pump. Refer to LDP diagnostic test for diagnosis of the new system.
