Diagnostic Test

WARNING: This page is about a different car, the 2016 RAM 3500 HD and 2016 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY ACTIVE DTC
NOTE:
Make sure the battery is fully charged.

NOTE:
The use of a approved special tool or Digital Multimeter such as a Fluke Meter that will not apply more than 20 milliamperes to a circuit are the only measurement tools to be used.

NOTE:
Probing of the circuit cavities at the ORC Module C1-A, C1-B, or C2-A body harness connectors is only to be done with a approved test lead from the (special tool #10159, Test Leads, Dedicated), test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures.
1. Turn the ignition on.
2. With the scan tool, read ORC DTC.
  Does the scan tool display active B0052-13-PASSENGER SEATBELT BUCKLE SENSOR - CIRCUIT OPEN DTC?
  
  Yes
  - Go To 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
CHECK (R58) PASSENGER SEAT BELT BUCKLE SWITCH SENSE CIRCUIT AND (R284) PASSENGER SEAT BELT BUCKLE SWITCH GROUND CIRCUIT FOR AN OPEN
WARNING:
Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
1. Disconnect the Passenger Seat Belt Buckle Switch harness connector.
2. Disconnect the ORC harness connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the test leads to the DVOM.
4. Measure the resistance of the (R58) Passenger Seat Belt Buckle Switch Sense circuit between the Passenger Seat Belt Buckle Switch harness connector cavity 1 and the ORC module body harness connector cavity C2 pin 21.
5. Measure the resistance of the (R284) Passenger Seat Belt Buckle Switch Ground circuit between the Passenger Seat Belt Buckle Switch harness connector cavity 2 and the ORC module body harness connector cavity C2 pin 19.
  Is the resistance greater than 3.0 Ohms on any of these circuits?
  
  Yes
  - Repair the (R58), (R284) Passenger Seat Belt Buckle Switch circuits for an open.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS-SYSTEM-VERIFICATION-TEST .
  No
  - Go To 3
VERIFY OPEN SWITCH
1. Replace the Passenger Seat Belt Buckle Switch. Refer to BUCKLE, SEAT BELT, REMOVAL .
2. Reconnect the vehicle body harness connector to the Driver Seat Belt Buckle Switch.
3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.
4. If the vehicle is equipped with the standard key ignition, follow this ignition on warning.
  WARNING:
  Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
5. If the vehicle is equipped with the keyless ignition, follow this ignition on warning.
  WARNING:
  Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
6. Connect the scan tool to the Data Link Connector - use the most current software available.
7. Use the scan tool and erase the stored DTCs.
8. Turn the Ignition OFF, and wait 15 seconds before turning the Ignition ON.
9. Wait one minute, and read active DTCs and if there are none present read the stored DTCs.
  Does the scan tool display active B0052-13-PASSENGER SEATBELT BUCKLE SENSOR - CIRCUIT OPEN DTC?
  
  Yes
  
  WARNING:
  Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the ORC in accordance with the Service Information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS-SYSTEM-VERIFICATION-TEST .
  No
  - Repair is complete.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS-SYSTEM-VERIFICATION-TEST .
