Pinpoint Test A

1. Ignition ON.
2. Using a scan tool, perform the PAM self-test.
3. Check the PAM DTCs  from the self-test.

Are any PAM DTCs recorded? 

• Yes: REFER to DTC Chart: Parking Aid Module (PAM) .
• No: GO to 2  .

1. While observing the message center, disable and enable the parking aid system.

Does the message center display PARK AID OFF when the parking aid system is disabled, and display PARK AID ON when the parking aid system is enabled? 

• Yes: GO to 3  .
• No: REFER to SYMPTOM CHART: MESSAGE CENTER .

1. Apply the parking brake.
2. Select REVERSE.
3. Using a scan tool, view PAM PIDs  .
4. Monitor the PAM TRANSGR PID.

Does the PID indicate YES (transmission in reverse)? 

• Yes: GO to 4  .
• No: REFER to DIAGNOSTIC PID CHART .

1. Select PARK.
2. Inspect the parking aid sensors for correct installation. Make sure the isolator rings are not rolled between the sensor and the bezel.

Are the parking aid sensors correctly installed? 

• Yes: GO to 5  .
• No: REMOVE and correctly INSTALL the parking aid sensor(s) in question.

1. Inspect the parking aid sensor isolator rings for deformation and damage.

Are the parking aid sensor isolator rings OK? 

• Yes: GO to 6  .
• No: INSTALL a new parking aid sensor or isolator ring as necessary. REFER to Parking Aid Sensor .

1. Apply the parking brake.
2. Select PARK.
3. Using a scan tool, view PAM PIDs  .
4. Using a scan tool, command the PAM REAR_TONE PID Active and then Inactive.

Does the PAM speaker sound when Active? 

• Yes: GO to 7  .
• No: INSTALL a new PAM speaker. PAM. TEST the system for normal operation.

  If the concern still exists, GO to 7  .

1. Ignition OFF.
2. Disconnect and inspect the PAM connector.
3. Repair:
   • corrosion (install new connector or terminals - clean module pins)
   • damaged or bent pins - install new terminals/pins
   • pushed-out pins - install new pins as necessary
4. Reconnect the PAM connector. Make sure it seats and latches correctly.
5. Operate the system and determine if the concern is still present.

Is the concern still present? 

• Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new PAM. REFER to Parking Aid Module (PAM) .
• No: The system is operating correctly at this time. Concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
