- If less than 1 V
Test for infinite resistance between the signal circuit and ground.
- If less than infinite resistance
  Repair the short to ground on the circuit.
- If infinite resistance
Test for less than 2 Ω in the signal circuit end to end.
- If 2 Ω or greater
  Repair the open/high resistance in the circuit.
- If less than 2 Ω
Replace the K17 electronic brake control module.
