GPS Receiver Power Connector Testing
1. Move the ATV to an outside area with a clear view of
the sky.
2. Open the left side engine compartment panel.
Disconnect the power connector from the GPS
receiver.
3. Start the engine.
4. Using a digital multimeter, perform the following tests:
• Measure VDC between pins 3 and 4. Verify there is B+
between these two pins.
• Measure VDC between pins 1 and 3. Verify there is 1.5
to 2.5 volts between these two pins.
• Measure VDC between pins 2 and 3. Verify there is 2.5
to 3.45 volts between these two pins.
5. If there is no power at the connector, inspect the wire
harness for broken wires.
6. If either of the CAN data signals are 0 VDC, check for
a loose connection in the wire harness.
7. If either of the CAN data signals are out of range, but
not 0, check from possible ECU or PIDD CAN
communication failures.
