WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- Normal Operation and Fault Conditions
The DDM/ PDM communicates with the SODR over the CAN. If the DDM/ PDM does not receive messages from the SODR, the side obstacle detection feature can be inoperative for the right side.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition DDM U0233:00 Lost Communication With Side Obstacle Detection Control Module "B": No Sub Type Information Sets when the PDM detects data messages are missing from the SODR. PDM U0233:00 Lost Communication With Side Obstacle Detection Control Module "B": No Sub Type Information Sets when the DDM detects data messages are missing from the SODR. Possible Sources
- Network communication concern
- DDM
- PDM
- SODR
- Y1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to Y2 No The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - Y2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, carry out a network test.
Does the SODR pass the network test?
Yes GO to Y3 No REFER to: ETHERNET MODULE COMMUNICATIONS NETWORK . - Y3 CHECK FOR SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, carry out the SODR self-test.
Are any voltage related Diagnostic Trouble Codes (DTCs) present?
Yes REFER to: Blind Spot Information System . No GO to Y4 - Y4 RECHECK THE DDM (DRIVER DOOR MODULE) / PDM (PASSENGER DOOR MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during PMI or the PMI may not have been performed.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) and repeat the PDM self-test.
Is DTC U0233:00 still present?
Yes GO to Y5 No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - Y5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0233 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 30 seconds.
- Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0233 set in other modules?
Yes INSTALL a new SODR. REFER to: Side Obstacle Detection Control Module . No INSTALL a new DDM/ PDM. REFER to: Driver Door Module (DDM) . REFER to: Passenger Door Module (PDM) .
