MERCURY SmartCraft Fault Codes


Mercury Engine does not start

 

Symptom - Remedy

 

1. The engine does not start and the VesselView screen appears different error codes - Make sure the E-stop switch is off.

 

2. The engine starts and stops with the button “START / STOP” with the gear engaged - Set the control levers to neutral and start engine. Periodic ignition will also start engine idle.

 

VesselView system malfunctions

 

VesselView does not turn on when key is turned ignition in position "ON".

 

1. The battery switch is off. Set the switch to ON.

 

2. Check and start the engine. If the engine does not start, check circuit breakers or fuses. For information on

location of circuit breakers or fuses refer to the user manual.

 

3. Loss of contact in the battery. Tighten battery cable connections

 

VesselView turns on but information is available for one engine only.

 

1. Disconnected engine battery, information about which cannot be displayed. Set the switch to ON.

 

2. Check and start all engines. If the engine does not start, check the circuit breakers or fuses. For information on the location of circuit breakers or fuses, refer to the user manual.

 

4. Turn on all engines.

Low Power

 

1. Throttle Malfunction - Verify that Cruise Control is disabled. Disable the Troll or Dock functions on the DTS control panel. See Special Features of Digital Throttle and Shift (DTS)

 

2. Damage or wrong size Propeller - Replace the propeller. Contact an authorized Mercury Diesel repair service.

 

3. Excess bilge water - Drain and establish the cause of the hit.

 

4. The vessel is overloaded or the load is improperly distributed - Reduce the load or distribute it more evenly.

 

5. Fouling by marine organisms or damage to the bottom of the vessel - Clean or, if necessary, repair.

 

6. Trims locked in the low position - Unlock the manual correction switch for automatic trimmers.

 

7. Low fuel quality - Use a cetane improver recommended by a Mercury Diesel Authorized Repair Facility.

 

8. Water in fuel - Drain fuel and refill with new fuel. The fuel filter may need to be drained or replace several times during this process.

 

7. Engine or electronic fuel system malfunction - Check the electronic engine fuel system with an authorized Mercury Diesel repair service.

 

8. DTC set for protection system - Check the DTCs of the protection system in the VesselView that cause a decrease in engine power. If you find, check the system with an authorized Mercury Diesel repair service.


Joystick

 

1. The joystick does not control the boat - Both remote control levers are not set to neutral. Set the remote control levers to neutral - One or both engines do not work. Start the engine or engines.

 

2. The response to the joystick is incorrect, or joystick works independently action - Make sure there are no radio or other sources near the joystick electronic or magnetic interference.

 

3. Joystick is not working properly and is installed fault code - Check VesselView for Security DTCs That Cause

engine power reduction. If you find, check the system in an authorized Mercury Diesel repair service.

 

4. Joystick not working, DTC not installed, swimming control enabled - Turn off swimming control.

 

Electronic Remote Control

 

1. ERC handle increases engine speed but not engages gears and the ship does not move

- Turn the ignition off and on

- Check the status of the Throttle Only button on the touch panel. Set the ERC knobs to neutral and press the shutdown button when the indicator is on.

- Engage gears manually. See Possible Operations

- Contact an authorized Mercury Diesel repair service.

 

2. The ERC crank controls the motor and drive, but not reaches full throttle

- If the engine reaches only 50% of the WOT (fully open throttle), check the DOCKING button on the DTS touch panel. Set the ERC handles to neutral and press the button shutdown if the indicator is on.

 - Look at VesselView if navigation control is enabled. Turn off cruise control.

- Check if the propeller is damaged. Check VesselView for DTCs for engine power reduction. If any, contact your authorized Mercury MerCruiser representative, to determine if the propellers need replacing.

 

3. The ERC crank controls the motor and drive, but not

reacts linearly.

- Check the status of the TROLL button on the touch panel. Set the ERC knobs to neutral and press the “TROLL” shut-off button if the indicator is on.

- Check whether mooring or cruise control is on. Turn off if it is on.

 

4. One ERC handle moves, but both respond

engine.

- Check the status of the “1 LEVER” button on the touch panel. If the corresponding indicator is on, set the ERC knobs to the neutral position and press the “1 LEVER” button to turn off.

 

ERC control unit, joystick and steering wheel not

work.

- Press the HELM button to restore control with the helm. (Only for ships with multiple helms.)

Steering System

 

1. The steering wheel works without resistance, but

drives a boat.

- The starboard ignition key is in the “off” state. Translate the key starboard ignition to on.

- Check and turn on the starboard engine.

- The starboard circuit breaker has tripped. Reset the circuit breaker.

 

2. The steering wheel does not steer the ship.

- To activate additional operations, set the joystick to the direction control mode. Contact an authorized Mercury Diesel repair service.

- Check the fluid level of the power steering system and add fluid if necessary. Read the information in the user manual for the power unit.

- See Possible Operations or Contact Mercury Diesel Authorized Repair Service.

 

3. The steering works, but the boat does not respond.

- Turn the ignition off and on.

- Check and turn on the left side engine.

- Check the operation of the trimmer.

- Check the fluid level of the power steering system and add fluid if necessary. View the user manual for power unit.

- Contact an authorized Mercury Diesel repair service.

 

4. Steering wheel out of limit stop - Switch ignition off and on to restore steering wheel self-centering, steering control and try to troubleshoot a fault code.
