Troubleshooting
This guide is aimed at providing aid for vehicle or marine technicians. Electrical experience and access to a digital multi-meter is required. End users should take their vehicle or boat to dealer and not attempt troubleshooting on their own

How to access Settings Menu
To enter Settings Menu press in all 4 corners within 5 seconds
No GPS Position
In the event that GPS signal is lost, the “No GPS” symbol will appear on the screen
- Navigate to the Satellite Status page. Settings > Maps > Satellite Status
- Verify that the GPS puck is detected
- If GPS puck is not detected, check the power and CAN connection to the GPS puck
- Verify that 3 green satellites are within view
- The GPS puck must be mounted flat with the connector facing down with a clear view of the sky and horizon.
- Dense tree cover, geography such as canyons, buildings, and metal will impede the GPS signal.
- Mount the GPS as high on vehicle/vessel as possible
Normal Operation non-Zero Off
Weak Signal with Zero Off
No GPS Communication
GPS Communicating with No Signal
Zero Off Cruise is not functioning
- Verify that a ZO GPS is connected: Settings > Maps > Satellite Status
- Verify that the engine has an E-Controls ECM
- Verify that there is good ground connections between throttle handle and engine
Display does not power up
- Turn IGN or ACC power on and take following measurements on connector B.
- Measure voltage between Vbatt to GND. If not 12V check for power on ACC terminal of key switch.
- Measure voltage between IGN to GND. If not 12V check for power on ACC terminal of key switch.
- If there is power, review other Display related questions to verify no other problem exists. If no other problem exists replace display.
- If power has been applied to video ground on the connector D (Pin 1 and Pin 2), internal damage will occur requiring display replacement.
Display is dim
- Verify brightness setting is at 100% (Settings > Display > Brightness)
- Access the auto brightness menu by selecting Settings > Display > Brightness
- Turn off GPS and Ambient light based brightness
- Some applications will dim light if Navigation lights are turned on. Verify lights are off
PDM does not function
- Verify that the PDM has power and that no fuses or circuit breakers have tripped
- Navigate to the PDM debug page: Settings > General > Debug
Note: On some displays, dealer permissions are required to access the debug page. Log into the display with dealer permissions: Settings > General > Restricted Settings > 9191
- Verify that PDMs are enabled and detected
- PDMs can be enabled from Setting > PDM menu
- If PDMs are not detected:
- Verify 12V power is provided to the the PDM on the large DTHD connectors
- Verify CAN connection
- Verify that the green connector is plugged in correctly
- The green connector can be forced in backwards. The CAN wires are in pins 1 and 12 on the left side of connector.
- CAN low is plugged into pin 1 and is typically green or blue
- CAN high is plugged into pin12 and is typically yellow or white
PDM output is not turning on
- Navigate to the PDM debug page: Settings > General > Debug
Note: On some displays, dealer permissions are required to access the debug page. Log into the display with dealer permissions: Settings > General > Restricted Settings > 9191
- Verify that PDMs are enabled and detected
- If not detected follow steps in section “PDM Does not function:
- Turn on the intended output
- Verify the state is greater than 0.
- A fully on output is listed as State: 100
- An H-bridge such as tab actuator or ballast pump in reverse will show -100
- Verify that there are no short or overcurrent faults (Fault Code 1 or 2)
Note: Open circuit Fault Code 3 commonly occurs in functioning outputs. This fault is ignored
- Check for 12V coming from the output pin
How to read the Main Debug Page
PDM Outputs
- Outputs are listed in a table
- The state is a value from -100 to 100
- A negative value indicates the output is in reverse for reversable loads such as pumps and acutators
- A value of 0 indicates an output is off
- Each output is protected for overcurrent and short to 12V
- 1 = short; 2 = overcurrent; 3 = open (open fault is ignored by the system)
PDM Inputs
- Digital inputs can either be switched to ground (1) or battery voltage (2)
- Analog inputs are a value from 0-1023
PDM output overcurrents
- If an output overcurrent by showing a lightning bolt indicator,
No Engine Data
- Navigate to Settings > Engine
- Verify the appropriate Engine Data Type is connected
- Verify baud rate is correct. For J1939 and NMEA2000 baud rate is 250k.
- Try toggling CAN Termination on/off. To work properly, the CAN bus must have to termination, typically one in display and one within ECU.
- Most engine data issues are related to CAN bus errors.
Tabs are not working (HV350 monochrome displays)
- Verify the latest software is loaded on the display
- Access the Tab Test Mode by going to Menu > Dealer Settings > 9191 > Tab Test Mode
- When entering Tab Test Mode, speed restrictions are disabled.
- Adjust tabs using switches. Value on screen should increase or decrease
- If on screen values do not change check wiring between switches and PDM
- Verify that there is 12V coming from the PDM
- Verify that the wiring is proper gauge and length per ABYC wiring requirements. Tab actuators typically run at 15A with a maximum of 25A. If wiring is too small or too long, tabs will run slow or not at all due to voltage drops
Cav Plate (Center Tab) does not deploy
- Verify that Center Tab auto retract and auto plane are disabled (Settings > Wake > Auto Plane/Auto Retract)
- Verify that Center tab +/- switches are being received on the PDM15 debug page (Settings > General > PDM 15)
- When the Cav Plate button is pressed you should see corresponding state change from 0 to 1 or 2 on the debug page
- On the Main Debug Page (Settings > General > Debug) verify that the Center tab state is not 0 when pressing the up/down button. Value will read 100 when going up and -100 when going down.
- Verify that there are no faults on the outputs
- Verify that there is 12V coming from the PDM
- Verify that the wiring is proper gauge and length per ABYC wiring requirements. Tab actuators typically run at 15A with a maximum of 25A. If wiring is too small or too long, tabs will run slow or not at all due to voltage drops
Surf Left/Right does not work
- Cruise must be enabled for the boat to enter surf mode
- The boat speed must be above 7mph for Surf tabs to deploy. To disable this function disable Autoretract in Settings > Wake > Surf
