- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C1887-2 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to G6 No REPAIR the circuit. - G6 CHECK THE SENSOR FOR A SHORT TO POWER
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C1887-2 Ground
Is any voltage present?
Yes REPAIR the affected circuits. No GO to G7 - G7 CHECK THE SENSOR FOR A SHORT TO VREF OR SIGNAL RETURN CIRCUITS
- Ignition OFF.
- Disconnect PAM C4226B.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C1887-2 Refer to C1887-1 Refer to C1887-2 Refer to C1887-3
Are the resistances greater than 10, 000 ohms?
Yes GO to G8 No REPAIR the affected circuits. - G8 CHECK THE SENSOR CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect right front outer parking aid sensor C1887.
- Disconnect PAM C4226B.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C1887-1 Refer to C4226B-2 Refer to C1887-2 Refer to C4226B-3 Refer to C1887-3 Refer to C4226B-12
Are the resistances less than 3 ohms?
Yes GO to G9 No REPAIR the affected circuit. - G9 INSTALL A KNOWN GOOD SENSOR
- Connect PAM C4226B.
- Install a known good sensor for the suspect right front outer parking aid sensor. REFER to: Front Parking Aid Sensor .
- Ignition ON.
- Using a diagnostic scan tool, clear the PAM Diagnostic Trouble Codes (DTCs) and repeat the self-test.
Is DTC B1B36:08, B1B36:31 or B1B36:1F still present?
Yes GO to G10 No INSTALL a new right front outer parking aid sensor. REFER to: Front Parking Aid Sensor . - G10 CHECK FOR CORRECT PAM (PARKING ASSIST CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PAM connectors.
- 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 connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new PAM. REFER to: Parking Assist Control Module (PAM) . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
