Standard SAE coverage depends on the connected vehicle exposing supported J1939, J1708/J1587 or CAN diagnostic data.

Standard faults, live parameters, vehicle identification, datalink health and supported aftertreatment data are the current focus. OEM programming, security access, parameter changes and proprietary service procedures require validated manufacturer-specific support.

!

Professional safety boundaries

Powerful diagnostics without pretending every command is universal

A forced DPF regeneration can create extremely high exhaust temperatures. Garage Monkey requires stationary-operation, parking-brake, neutral, wheel-chock, leak and temperature checks. The final command remains locked until the connected engine and a validated OEM-specific routine are identified.
