- Ignition Off.
- Remove the KR22 Fuel Heater Relay from X50A Fuse Block-Underhood.
- Test for 70 - 110 Ω between terminals 85 and 86.
- If not between 70 - 110 Ω
Replace the KR22 Fuel Heater Relay.
- Go to next step : If between 70 - 110 Ω
- If not between 70 - 110 Ω
- Test for infinite resistance between the following terminals :
- C3/30 and B3/86
- C3/30 and B1/87
- C3/30 and C1/85
- C1/85 and B1/87
- 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 B3/86 and 12 V.
- Install a jumper wire between relay terminal C1/85 and ground.
- Test for less than 2 Ω between terminals C3/30 and B1/87.
- If 2 Ω or greater
Replace the KR22 Fuel Heater Relay.
- Go to next step : If 2 Ω or less
- If 2 Ω or greater
- All OK
