        Note


        • Confirm the terminal numbers before connecting them. Connection with a wrong terminal can damage the engine.

        • Turn off all electrical systems before connecting the terminals.

        • When checking ISC function, the transmission should be in the neutral position.

      3. A01E1L3E01

        After connecting terminals (TC and CG), check that the engine speed changes to approximately 1,000 to 1,500 rpm for 5 seconds, and then returns to idle speed.
