URAL ENGINE MANAGEMENT SYSTEM BLINK DIAGNOSTICS
Introduction
A basic blink code system has been implemented on the Ural EFI bikes to aid EMS (Engine Management System)
diagnostics without the need for an additional computer diagnostic tool, greatly helping the user when during
travels. When activated, the MIL (malfunction indicator lamp) blinks out a code sequence relating to the fault.
Operation
When the MIL is continuously lit with the key on, an EMS fault has occurred. Activate the blink code by turning
the key on and toggling the key switch 3 times (Off->On->Off->On->Off->On) within 10 seconds. MIL will blink
the code “02” indicating the ECU is in blink mode.
Once in blink mode, the ECU will blink the code “02” first and then blink a unique code for each possible system
fault in a consecutive fashion, before cycling back to the beginning.
The ECU will remain in this mode until the Key switch is turned off for more than 10 seconds.
