Pinpoint Test F
- CHECK THE SPEAKER CONNECTOR FOR CORRECT LATCHING
- Ignition OFF.
- Inspect the parking aid speaker connector for correct latching by pulling on the latched connector.
Is the connector latched?
- Yes: GO to 2 .
- No: Correctly LATCH the connector.
- MEASURE THE PARKING AID SPEAKER RESISTANCE
- Disconnect: Parking Aid Speaker.
- Measure:
Parking Aid Speaker Parking Aid Speaker C2024 (component side) C2024 (component side) Pin Circuit Measurement / Action Pin Circuit 2 - 1 -
Is the resistance between 40 and 60 ohms?
- Yes: For DTC B1B52:14, GO to 3
.
For DTC B1B52:12, GO to 6.
- No: INSTALL a new parking aid speaker. REFER to Parking Aid Speaker .
- CHECK THE PARKING AID SPEAKER CIRCUITRY FOR A SHORT TO GROUND
- Disconnect: PAM.
- Measure:
PAM Ground C3267 Ground Pin Circuit Measurement / Action Pin Circuit 2 CMP09 (BN/BU) - Ground 6 RMP09 (BU/GN) - Ground
Are the resistances greater than 10, 000 ohms?
- Yes: GO to 4 .
- No: REPAIR the circuit in question.
- CHECK THE PARKING AID SPEAKER CIRCUITRY FOR AN OPEN
- Measure:

Are the resistances less than 3 ohms?
- Yes: GO to 5 .
- No: REPAIR the circuit in question.
- Measure:
- CHECK THE PARKING AID SPEAKER CIRCUITS FOR A SHORT TO EACH OTHER
- Measure:
PAM PAM C3267 C3267 Pin Circuit Measurement / Action Pin Circuit 2 CMP09 (BN/BU) 6 RMP09 (BU/GN)
Is the resistance greater than 10, 000 ohms?
- Yes: GO to 7.
- No: REPAIR the circuits.
- Measure:
- CHECK THE PARKING AID SPEAKER CIRCUITRY FOR A SHORT TO VOLTAGE
- Disconnect: Parking Aid Speaker.
- Disconnect: PAM.
- Ignition ON.
- Measure:
PAM Ground C3267 Ground Pin Circuit Measurement / Action Pin Circuit 2 CMP09 (BN/BU) - Ground 6 RMP09 (BU/GN) - Ground
Is any voltage present?
- Yes: REPAIR the circuit in question.
- No: GO to 7 .
- CHECK FOR CORRECT PAM OPERATION
- Disconnect and inspect the PAM connector.
- 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
- Reconnect the PAM connector. Make sure it seats and latches correctly.
- 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. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
