Pinpoint Test AE: The Side Obstacle Detection Control Module RH (Sod-R) Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different variant/trim than selected.
  1. AE1 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) VOLTAGE SUPPLY CIRCUITS FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: SODR C4370  .
    • Ignition ON.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C4370-2  VOLTAGE Ground

    Is the voltage greater than 11 volts? 

    1. Yes  : GO to AE2 
    2. No  : VERIFY the BJB  fuse 23 (15A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short.
  2. AE2 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) GROUND CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C4370-5  OHM Ground
      C4370-6  OHM Ground

    Are the resistances less than 3 ohms? 

    1. Yes  : GO to AE3 
    2. No  : REPAIR the circuit.
  3. AE3 CHECK THE MEDIUM SPEED CONTROLLER AREA NETWORK (MS-CAN) CIRCUITS BETWEEN THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN 
    • Disconnect: GWM C2431  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C4370-3  OHM C2431-23 
      C4370-4  OHM C2431-22 

    Are the resistances less than 3 ohms? 

    1. Yes  : GO to AE4 
    2. No  : REPAIR the circuit in question.
  4. AE4 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION 
    • Ignition OFF.
    • Disconnect and inspect all the SODR  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 SODR  connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    1. Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new SODR  .

      REFER to: SIDE OBSTACLE DETECTION CONTROL MODULE .

    2. 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.
