Circuit/System Testing

Vehicle OFF, disconnect the harness connector at the B208 Fuel Door Status Switch Assembly. It may take up to 2 minutes for all vehicle systems to power down.
Test for less than 10 Ω between the ground circuit terminal 2 and ground.
- If 10 Ω or greater
1. Vehicle OFF.
2. Test for less than 2 Ω in the ground circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, repair the open/high resistance in the ground connection.
- Go to next step: If less than 10 Ω
Vehicle in Service Mode, test for 4.8 - 5.2 V between the 5 V reference circuit terminal 1 and ground.
- If less than 4.8 V
1. Vehicle OFF, disconnect the harness connector at the K114B Hybrid Powertrain Control Module 2.
2. Test for infinite resistance between the 5 V reference circuit and ground
  - If less than infinite resistance, repair the short to ground on the circuit.
  - Go to next step: If infinite resistance
3. Test for less than 2 Ω in the 5 V reference circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the K114B Hybrid Powertrain Control Module 2.
- If greater than 5.2 V
1. Vehicle OFF, disconnect the harness connector at the K114B Hybrid Powertrain Control Module 2, Vehicle in Service Mode.
2. Test for less than 1 V between the 5 V reference circuit and ground.
  - If 1 V or greater, repair the short to voltage on the circuit.
  - If less than 1 V, replace the K114B Hybrid Powertrain Control Module 2.
- Go to next step: If between 4.8 - 5.2 V
Test or replace the B208 Fuel Door Status Switch Assembly.
