Circuit/System Testing

  1. Vehicle OFF, disconnect the harness connector at the P48 Pedestrian Alert Sound Speaker. Vehicle in Service Mode.
  2. Command the Pedestrian Alert Sound System parameter ON using the scan tool.
  3. Test for 5-7 V between each speaker signal circuit terminal 1 and terminal 2 and ground.
    • If less than 5 V 
    1. Vehicle OFF, disconnect the harness connector at the K132 Pedestrian Alert Sound Control Module.
    2. Test for infinite resistance between the signal circuits and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. 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 K132 Pedestrian Alert Sound Control Module.
    • If greater than 7 V 
    1. Vehicle OFF, disconnect the harness connector at the K132 Pedestrian Alert Sound Control Module. Vehicle in Service Mode.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K132 Pedestrian Alert Sound Control Module.
    • If between 5-7 V 
  4. Test or replace the P48 Pedestrian Alert Sound Speaker.
