GPS Receiver Power Connector Testing
1. Move the snowmobile 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.
NOTICE
On snowmobiles with the GPS receiver mounted to a
hood bag, disconnect the power plug from inside the
bag.
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 possible ECU or PIDD CAN
communication failures.
