The CNG fuel system wiring in your vehicle is protected from short circuits by five fuses and a relay. They are located in the engine compartment fuse block. If a CNG fuel system fuse is bad, your bi-fuel vehicle will start and operate on gasoline.
The fuse block is located in the engine compartment on the driver's side of the vehicle.
Fuses | Usage |
---|---|
21 | Passenger side CNG and gasoline injectors |
23 | Driver's side CNG and gasoline injectors |
33 | High Pressure Lockoff Main |
35 | Low Pressure Lockoff |
63 | High Pressure Lockoff for Tanks 1 and 3 |
Relays | Usage |

There is also an inline fuse located on the left side of the frame rail under the CNG tank bracket. It controls the high pressure lockoff for Tank 2. If you need to access this fuse, contact your dealer.
