Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. VERIFY ACTIVE DTC 
    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.

    NOTE:

    Using the wiring diagram/schematic as a guide check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

    NOTE:

    If after the harness inspection it appears the impact sensor connector is only seated halfway. Reseat the harness connector into the impact sensor and lock the tab. Follow the instructions below checking for active codes.

    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.

    NOTE:

    Make sure the battery is fully charged.

    1. Turn the ignition on.
    2. With the scan tool, read ORC DTCs.

      Does the scan tool display active B0096-49-RIGHT SIDE ACCELERATION SENSOR 1 - INTERNAL ELECTRONIC FAILURE, U0175-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 1, U0176-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 2, U11B0-00-LOST COMMUNICATION W/ RIGHT SIDE SATELLITE SENSOR 4 - DTC?

      Yes 

      • Check for all other internal and lost communication codes indicated in the right side impact sensor daisy chain wiring, starting with DTC B0096-49-RIGHT SIDE ACCELERATION SENSOR 1 - INTERNAL ELECTRONIC FAILURE, then DTC U0175-00-LOST COMMUNICATION W/RIGHT SIDE SATELLITE ACCELERATION SENSOR 1. Refer to Diagnosis and Testing . Then Go To  2.

      No 

  2. CHECK THE (R14, R16) RIGHT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TO VOLTAGE

    2. Disconnect the ORC harness connectors.
      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.

    3. Measure the voltage of the (R14) Right Side Impact Sensor 1 Signal circuit cavity 4 and (R16) Right Side Impact Sensor 1 Ground circuit cavity 3 at the Right Side Impact Sensor 1 harness connector.

      Is there any voltage present?

      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:

    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. Measure the resistance between ground and the (R16) Right Side Impact Sensor 1 Ground circuit at the Right Side Impact Sensor 1 harness connector cavity 3.
    2. Measure the resistance between ground and the (R14) Right Side Impact Sensor 1 Signal circuit between at the Right Side Impact Sensor 1 harness connector cavity 4.

      Is the resistance below 100K Ohms?

      Yes 

      • Repair the (R14, R16) Right Side Impact Sensor 1 circuits for a short to ground.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  4.
  4. CHECK THE (R14, R16) RIGHT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TOGETHER 
    Fig 3: Checking Right Side Impact Sensor 1 Circuit
    GC0089850Courtesy of CHRYSLER LLC
    1. Measure the resistance between the (R14) Right Side Impact Sensor 1 Signal and (R16) Right Side Impact Sensor 1 Ground circuits at the Right Side Impact Sensor 1 harness connector cavity 3 and 4.

      Is the resistance below 100K Ohms?

      Yes 

      • Repair the (R14, R16) Right Side Impact Sensor 1 circuits shorted together.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  5.
  5. CHECK THE (R16) RIGHT SIDE IMPACT SENSOR 1 GROUND CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
