DIAGNOSTIC PLUGS
Power Test Plugs
A set of power test and fuel pump prime plugs allows a
technician to test several electrical circuits on the
snowmobile.
The plugs can be accessed behind the left door panel.
NOTE: The AC power test plug is located on the
ha
ndlebar wiring harness on 2011-later models.
Shown below is the Chassis Power-Up Harness,
PS-47269-A, and Dual Power/Fuel Pump Prime Adapter,
PS-50805.
When both tools are used together, the technician can
sup
ply power to the ECM PWR and DC PWR plugs. This
is required for enabling the security function on 2012
models. Also, the Dual PWR/Fuel Pump Prime Adapter
can connect to the fuel pump prime plug.
DC PWR Plug
Connect the Chassis Power-Up Harness to the DC PWR
plug to supply battery power to the following components:
• Instrument cluster
• DC accessory power points
• LED tail lamp/brake lamp
ECM PWR Plug
Connect the Chassis Power-Up Harness to the ECM
PWR plug to supply battery voltage to the following
components:
• Digital Wrench® communication connector
•ECU
• Chassis relay driver coil
• VES solenoid
• DC Power capacitor
• Fuel pump power side
Fuel Pump Prime Plug
Use the Chassis Power-Up Harness and Dual PWR/Fuel
Pump Prime Adapter to supply battery voltage to the fuel
pump. This is useful for purging the fuel system of air or
testing fuel pump pressure with the engine off.
AC PWR Plug
The AC circuits can be tested with a multimeter at the AC
PWR plug. AC circuits include the head lights, hand
warmers, and thumb warmer.
NOTE: The AC power test plug is located on the
ha
ndlebar wiring harness on 2011-later models.
CHASSIS POWER-UP HARNESS
PS-47296-A
DUAL PWR/FUEL PUMP PRIME
PS-50805
Verify the fuel hoses are connected to the fuel pump and
fuel rail before connecting the fuel pump prime plug to
the engine harness.
DO NOT CONNECT BATTERY VOLTAGE TO THE AC
PWR TEST PLUG. SEVERE ELECTRICAL SYSTEM
DAMAGE WILL OCCUR.
