Pinpoint Test E: DTC B1B52:12 Or DTC B1B52:14
NOTE:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- E1 CHECK THE SPEAKER CONNECTOR FOR CORRECT LATCHING
- Ignition OFF.
- Inspect the parking aid speaker connector C4015 for correct latching by pulling on the latched connector.
Is the connector latched?
- Yes : GO to E2 .
- No : Correctly latch the connector.
- E2 MEASURE THE PARKING AID SPEAKER RESISTANCE
- Disconnect: Rear Parking Aid Speaker C4015 .
- Measure the component side resistance
between:
Positive Lead Negative Lead Pin Circuit Pin Circuit C4015 pin 2 - C4015 pin 1 -
Is the resistance between 40 and 60 ohms?
- Yes
: If DTC B1B52:14 was recorded, GO to E3
.
If DTC B1B52:12 was recorded, GO to E6.
- No : INSTALL a new parking aid speaker. REFER to PARKING AID MODULE (PAM) .
- E3 CHECK THE REAR PARKING AID SPEAKER CIRCUITS FOR A SHORT TO GROUND
- Disconnect: PAM C4014 .
- Measure the resistance
between:
Positive Lead Negative Lead Pin Circuit Pin Circuit C4014-2 CMP09 (BN/BU) - Ground C4014-6 RMP09 (BU/GN) - Ground
Are the resistances greater than 10, 000 ohms?
- Yes : GO to E4 .
- No : REPAIR the circuit in question.
- E4 CHECK THE REAR PARKING AID SPEAKER CIRCUITS FOR AN OPEN
- Measure the resistance
between:
Positive Lead Negative Lead Pin Circuit Pin Circuit C4014-2 CMP09 (BN/BU) C4015-2 CMP09 (BN/BU) C4014-6 RMP09 (BU/GN) C4015-1 RMP09 (BU/GN)
Are the resistances less than 3 ohms?
- Yes : GO to E5 .
- No : REPAIR the circuit in question.
- Measure the resistance
between:
- E5 CHECK THE PARKING AID SPEAKER CIRCUITS FOR A SHORT TO EACH OTHER
- Measure the resistance
between:
Positive Lead Negative Lead Pin Circuit Pin Circuit C4014-2 CMP09 (BN/BU) C4014-6 RMP09 (BU/GN)
Is the resistance greater than 10, 000 ohms?
- Yes : GO to E7.
- No : REPAIR the circuits.
- Measure the resistance
between:
- E6 CHECK THE PARKING AID SPEAKER CIRCUITRY FOR A SHORT TO VOLTAGE
- Disconnect: PAM C4014 .
- Ignition ON.
- Measure the voltage
between:
Positive Lead Negative Lead Pin Circuit Pin Circuit C4014-2 CMP09 (BN/BU) - Ground C4014-6 RMP09 (BU/GN) - Ground
Is any voltage present?
- Yes : REPAIR the circuit in question.
- No : GO to E7 .
- E7 CHECK FOR CORRECT PAM OPERATION
- Disconnect and inspect the PAM connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged 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.
