Circuit/System Testing

NOTE:

It may take up to 2 min for all vehicle systems to power down before an accurate ground or low reference circuit continuity test can be performed.

Ignition/Vehicle & All vehicle systems - Off
Disconnect the electrical connector: K132 Pedestrian Alert Sound Control Module
Test for less than 10 ohms between the test points: Ground circuit terminal 3 & Ground
- If 10 ohms or greater
1. Disconnect the ground connection: G302
2. Test for less than 2 ohms between the test points: Ground circuit terminal 3 & Terminal G302
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Repair the open/high resistance in the ground connection.
- Go to next step: If less than 10 ohms
Ignition - On / Vehicle - In Service Mode
Verify a test lamp turns On between the test points: B+ circuit terminal 10 & Ground
- If the test lamp does not turn On and the circuit fuse is OK
1. Ignition/Vehicle - Off & Remove - Test lamp
2. Test for less than 2 ohms between the test points: B+ circuit terminal 10 & Output terminal @F9UA Fuse
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Verify the fuse is OK and there is voltage at the fuse.
- If the test lamp does not turn On and the circuit fuse is open
1. Ignition/Vehicle - Off & Remove - Test lamp
2. Test for infinite resistance between the test points: B+ circuit terminal 10 & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance - Replace the component: K132 Pedestrian Alert Sound Control Module
- Go to next step: If the test lamp turns On
Ignition/Vehicle - Off
Connect the electrical connector: K132 Pedestrian Alert Sound Control Module
Disconnect the electrical connector: P48 Pedestrian Alert Sound Speaker
Test for less than 10 ohms between the test points: Low Reference terminal 2 & Ground
- If 10 ohms or greater
1. Disconnect the electrical connector: K132 Pedestrian Alert Sound Control Module
2. Test for less than 2 ohms between the test points: Low Reference terminal 2@Component harness & Terminal 8@Control module harness
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Replace the component: K132 Pedestrian Alert Sound Control Module
- Go to next step: If less than 10 ohms
Ignition - On / Vehicle - In Service Mode & Transmission in Drive
Test for 5 to 7 V between the test points: Control circuit terminal 1 & Ground
- If less than 5 V
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: K132 Pedestrian Alert Sound Control Module
3. Test for infinite resistance between the test points: Control circuit terminal 1@Component harness & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - Go to next step: If infinite resistance
4. Test for less than 2 ohms between the test points: Control circuit terminal 1@Component harness & Terminal 9@Control module harness
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Replace the component: K132 Pedestrian Alert Sound Control Module
- If greater than 7 V
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: K132 Pedestrian Alert Sound Control Module
3. Ignition - On / Vehicle - In Service Mode
4. Test for less than 1 V between the test points: Control circuit terminal 1@Component harness & Ground
  - If 1 V or greater - Repair the short to voltage on the circuit.
  - If less than 1 V - Replace the component: K132 Pedestrian Alert Sound Control Module
- Go to next step: If between 5 and 7 V
Test or replace the component: P48 Pedestrian Alert Sound Speaker
