Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Durango. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY ACTIVE DTC
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 the use of Breakout Box 8443-55 to prevent vehicle wiring harness connector damage during diagnostic procedures.

NOTE:
Make sure the battery is fully charged.
1. Turn the ignition on.
2. With the scan tool, read ORC DTC.
  Does the scan tool display active B0050-13-DRIVER SEATBELT BUCKLE SENSOR - CIRCUIT OPEN DTC?
  
  Yes
  - Go To 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .

3. Connect the test leads to the DVOM.
4. Measure the resistance of the (R57) Driver Seat Belt Buckle Switch Sense circuit between the Driver Seat Belt Buckle Switch harness connector cavity 1 and the ORC module body harness connector cavity C1-B 73.
5. Measure the resistance of the (R59) Driver Seat Belt Buckle Switch Ground circuit between the Driver Seat Belt Buckle Switch harness connector cavity 2 and the ORC module body harness connector cavity C1-B 74.
  Is the resistance greater than 1.0 Ohm on any of these circuits?
  
  Yes
  - Repair the (R57, R59) Driver Seat Belt Buckle Switch circuits for an open in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
