Steering Motor Circuits
Use the diode test function of a digital multimeter
to check the steering motor circuit.
Connect the meter leads as listed in the table
below.
Results:
• Readings as listed in table indicate circuit is
good.
• No reading (OL or ∞) indicates an open circuit.
• A reading of zero (0) indicates an short circuit.
Replace faulty module.
Steering Sensor Circuits
Use the diode test function of a digital multimeter
to check the signal circuit.
Connect the BLACK meter lead to the wire listed
in the table, connect the RED meter lead to
engine ground.
Results:
• Readings as listed in table indicate circuit is
good.
• No reading (OL or ∞) indicates an open circuit.
• A reading of zero (0) indicates an short circuit.
Replace faulty module.
CANbus Circuit
Use a digital multimeter with appropriate test
probe leads to measure sensor circuit resistance.
Connect the positive meter lead to the DPS Mod-
ule connector/ wire listed in the table.
Connect the negative meter lead to engine
ground.
Results:
• No reading (OL or ∞) indicates an open circuit.
• A reading of zero (0) indicates an short circuit.
Replace faulty module.
Steering Pressure Sensor Tests
Use Evinrude Diagnostics software v 6.1 or higher
to observe Port Pressure and Starboard Pressure.
