DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BCM U0233:87 Lost Communication With Side Obstacle Detection Control Module "B": Missing Message A continuous memory DTC that sets in the BCM if messages from the SODR through the GWM are missing. Possible Sources
- Communication network concern
- Battery voltage concern
- GWM concern
- SODR
- BCM
- O1 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Connect the diagnostic tool.
- Using a diagnostic scan tool, perform a network test.
Does the SODR pass the network test?
Yes GO to O2 No REFER to: Communications Network . - O2 CHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC B11D9:16, B11D9:17, U3006:16, U3006:17, U3007:16, U3007:17, U3013:16, U3013:17, U3014:16 or U3014:17 recorded?
Yes For DTC B11D9:16, U3006:16, U3007:16, U3013:16 or U3014:16, GO to Pinpoint Test Y For DTC B11D9:17, U3006:17, U3007:17, U3013:17 or U3014:17, GO to Pinpoint Test AA No GO to O3 - O3 RETRIEVE THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform the SODL self-test.
Are any SODR Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Blind Spot Information System . No GO to O4 - O4 RECHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0233:87 still present?
Yes GO to O5 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. - O5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0233:87 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve all
Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0233:87 set in other modules?
Yes GO to O6 No GO to O7 - O6 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION
- Disconnect and inspect 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?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SODR. REFER to: Side Obstacle Detection Control Module (SODCM) . 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. - O7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Disconnect and inspect all BCM 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 BCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCM. REFER to: Body Control Module (BCM) . No The system is operating correctly at this time.
