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
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
All OK.
