- If not between 70 - 110 Ω
- Test for infinite resistance between the following terminals:
- 3 and 1
- 3 and 5
- 3 and 2
- 2 and 5
- If less than infinite resistance
Replace the KR22 Fuel Heater Relay.
- Go to next step: If infinite resistance
- Install a 20 A fused jumper wire between relay terminal 2 and 12 V.
- Install a jumper wire between relay terminal 1 and ground.
- Test for less than 2 Ω between terminals 3 and 5.
- If 2 Ω or greater
Replace the KR22 Fuel Heater Relay.
- Go to next step: If 2 Ω or less
