Circuit/System Testing

Vehicle OFF, disconnect the harness connector at the P48R Pedestrian Alert Sound Speaker - Rear.
Vehicle in propulsion system active mode, Transmission in Reverse
Test for 3.5 - 5.5 V between control circuit terminal listed below and ground:
- Control circuit terminal 1
- Control circuit terminal 2
- If less than 3.5 V
1. Vehicle OFF, disconnect the harness connector at the K132 Pedestrian Alert Control Module.
2. Test for infinite resistance between the control 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 control 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 Control Module.
- If greater than 5.5 V
1. Vehicle OFF, disconnect the harness connector at the K132 Pedestrian Alert Control Module. Vehicle ON.
2. Test for less than 1 V between the control 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 Control Module.
- Go to next step: If between 3.5 - 5.5 V
Test or replace the P48R Pedestrian Alert Sound Speaker - Rear.
