for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Communications Network - System Operation and Component Description .
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BCM U0200:87 Lost Communication With 'Door Control Module B': Missing Message A continuous memory DTC that sets in the BCM if messages received from the PDM through the GWM are missing. Possible Sources
- Communication network concern
- Battery voltage concern
- GWM concern
- PDM
- BCM
NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during the PMI or the PMI may not have been carried out. - L1 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Connect the diagnostic tool.
- Using a diagnostic scan tool, perform a network test.
Does the PDM pass the network test?
Yes GO to L2 No REFER to: Communications Network . - L2 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 CMDTCs.
Is DTC U3006:16, U3006:17, U3007:16, U3007:17, U3013:16, U3013:17, U3014:16 or U3014:17 recorded?
Yes For DTC U3006:16, U3007:16, U3013:16 or U3014:16, GO to Pinpoint Test V For DTC U3006:17, U3007:17, U3013:17 or U3014:17, GO to Pinpoint Test W No GO to L3 - L3 RETRIEVE THE PDM (PASSENGER DOOR MODULE) DTCS
- Using a diagnostic scan tool, perform the PDM self-test.
Are any PDM DTCs present?
Yes REFER to: Locks, Latches and Entry Systems . No GO to L4 - L4 RECHECK THE BCM (BODY CONTROL MODULE) CMDTCS
- Using a diagnostic scan tool, clear the DTCs.
- Wait 10 seconds.
- Using a diagnostic scan tool, check the BCM CMDTCs.
Is DTC U0200:87 present?
Yes GO to L5 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. - L5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0200:87 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear the DTCs.
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve all
CMDTCs.
Is DTC U0200:87 set in other modules?
Yes GO to L6 No GO to L7 - L6 CHECK FOR CORRECT PDM (PASSENGER DOOR MODULE) OPERATION
- Disconnect and inspect all PDM 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 all PDM 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 CCHECK 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 PDM. REFER to: Passenger Door Module (PDM) . 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. - L7 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 all 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 Technical Service Bulletins (TSBs). If a 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. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
