DPS System Tests
The DPS module circuits can be tested on or off
the outboard.
Disconnect the battery cables at the battery. Dis-
connect the electrical connectors from the DPS
module.
Steering Ground Circuits
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:
• 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 Supply Circuits
Use the diode test function of a digital multimeter
to check the supply circuits.
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.
NOTICE
Use appropriate test leads or adapters such
as Test Probe Kit, P/N 342677, when perform-
ing electrical tests.
NEVER pierce the insulation of the engine
wiring, or use any piercing-style test probe.
Piercing insulation damages the wire and can
cause other unintended electrical problems.
