Problem: A user reported a failure when trying to reset the service light on a 2013 Sea-Doo GTX 215 (Engine: M7791970) using the OBDSTAR iScan Sea-Doo. While the Marine Scanner could power on and read diagnostic codes, selecting the “Reset Service Light” function triggered an error.
The error message:
“Ausfuhrung fehlgeschlagen (12-Unterstutzt nicht die Unterfunktion-ungultiges Format)
Mogliche Grunde:
- Befehlsfehler bei der Gerateanforderungsfunktion
- Die aktuellen Fahrzeugstatusbedingungen sind nicht erfullt.”
“Execution failed (12 – Does not support sub-function – Invalid format)
Possible Reasons:
- Command error in the device request function
- The current vehicle status conditions are not met.”
This translates to an “unsupported sub-function” error, indicating the command was sent to a control unit that doesn’t support it.
Root Cause and Solution
The issue arises because the “Reset Service Light” function within the instrument cluster or dashboard menu is not supported for this Sea-Doo model. Attempting to use it causes the documented error.
The correct procedure is to perform the reset through the Engine Control Unit (ECU):
- Connect your iScan Marine Scanner to the watercraft.
- Navigate to the main menu and select “Engine System.”
- Within the Engine System, enter the “Service Function” or “Maintenance” menu.
- Here, you will find the valid options to reset the service interval or maintenance light.
By accessing the service function via the engine system, the correct command is sent, and the reset can be completed successfully.
Summary
If your OBDSTAR iScan Sea-Doo Marine Scanner shows an “Execution failed, Does not support sub-function” error when resetting the service light, avoid the dashboard menu. Always use the Engine System > Service Function path for a successful reset on models like the Sea-Doo GTX 215.
