Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Ignition/Vehicle & All vehicle systems - Off
- Disconnect the electrical connector: @K111 Fuel Pump Driver Control Module & A7 Fuel Pump and Level Sensor Assembly
- Test for less than 2 ohms between the test points:
- Control circuit terminal 8 @Control module harness & Terminal 1 @ Component harness
- Control circuit terminal 9 @Control module harness & Terminal 2 @ Component harness
- Control circuit terminal 24 @Control module harness & Terminal 3 @ Component harness
- If 2 ohms or greater
Repair the open/high resistance in the circuit.
- Go to next step: If less than 2 ohms
- Test for infinite resistance between the test points:
- Control circuit terminal 8@Control module harness & Control circuit terminal 9@Control module harness
- Control circuit terminal 8@Control module harness & Control circuit terminal 24@Control module harness
- Control circuit terminal 9 @Control module harness & Control circuit terminal 24@Control module harness
- If less than infinite resistance
Repair the short between the circuits.
- Go to next step: If infinite resistance
- Verify a condition does not exist with the component: A7 Fuel Pump and Level Sensor Assembly
- Restrictions
- Debris
- Contamination
- If a condition exists
Repair or replace as necessary.
- Go to next step: If no condition exists
- Replace the component: A7 Fuel Pump and Level Sensor Assembly
- Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
- Verify the DTC does not set.
- If the DTC sets
Replace the component: K111 Fuel Pump Driver Control Module
- Go to next step: If the DTC does not set
- If the DTC sets
- All OK.
NOTE:
Remove the required components as necessary.
