The ignition is on.
Wait 10 seconds.
Using a scan tool, perform a continuous memory self-test.
Check the SODL diagnostic trouble codes (DTCs).
Is DTC U0199:00 still present?
Yes
GO to I6
No
The system is currently operating correctly. The DTC may have been set due to high network traffic or an intermittent condition.
I6 CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK PROBLEMS
CHECK the vehicle service history for recent service actions related to the DDM or SODL. If recent service history is found:
make sure the correct replacement module was installed
HVBOM can be used to verify the correct part installation.
make sure the replacement module configuration was correct
reconfigure the module using the original data if the previous configuration is suspected
make sure the module was not obtained from a similar vehicle and installed on the customer's vehicle
Reinstall the replaced module in the original vehicle and obtain a new replacement module.
Operate the system and determine whether the observed symptom persists.
Is the observed symptom still present?
Yes
GO to I7
No
The system is currently operating correctly. The concern may have been caused by incorrect part replacement procedures or incorrect module configuration.
I7 CHECK DDM (DRIVER DOOR MODULE) OPERATION
Ignition OFF.
Disconnect and inspect all DDM connectors and the corresponding harness connectors.
Repair:
corrosion (install new connector or terminals - clean module pins)
damaged or bent pins - install new terminals/pins
backed-out pins - install new pins as necessary
Reconnect the DDM connectors and the corresponding harness connectors. Make sure they are installed and locked 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 (TSB). If a TSB exists for this concern, STOP this test and FOLLOW the TSB instructions. If no TSB applies to this concern, INSTALL a new DDM. REFER TO: Driver Door Module (DDM) (419-10 Multifunction Electronic Modules, Removal and Installation).
No
The system is currently operating correctly. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.

J1 VERIFY CUSTOMER CONCERN
The ignition is on.
Make sure the observed symptom is present.
Is the observed symptom present?
Yes
GO to J2
No
CLEAR the DTC. The system is currently operating correctly. The DTC may have been set due to high network traffic or an intermittent condition.
J2 CHECK THE COMMUNICATION NETWORK
Using a scan tool, perform the network test.
Does the PDM pass the network test?
Yes
GO to J3
No
REFER to the Symptom Chart: Communication Network. REFER to: Communication Network (418-00 Module Communications Network, Diagnosis and Testing).
J3 PERFORM SODR (RIGHT SIDE OBSTACLE DETECTION MODULE) SELF-TEST
Using a diagnostic scan tool, perform the SODR self-test.
Are there any non-network diagnostic trouble codes (DTCs)?
Yes
CHECK all non-network diagnostic trouble codes (DTCs). REFER TO the SODL and SODR DTC Charts in this section.
No
GO to J4
J4 PERFORM PDM (PASSENGER DOOR MODULE) SELF-TEST
Using the diagnostic scan tool, perform the PDM self-test.
Are there any non-network diagnostic trouble codes (DTCs)?
Yes
CHECK all non-network diagnostic trouble codes (DTCs). Refer to the PDM DTC chart. REFER TO: Locks, Latches and Entry Systems (501-14 Door Handles, Locks, Latches and Entry Systems, Diagnosis and Testing).
Using a diagnostic scan tool, clear the SODR diagnostic trouble codes (DTCs).
Ignition OFF.
The ignition is on.
Wait 10 seconds.
Using a scan tool, perform a continuous memory self-test.
Check the SODR diagnostic trouble codes (DTCs).
IS DTC U0200:00 STILL PRESENT?

J7 CHECK PDM (PASSENGER DOOR MODULE) OPERATION
Ignition OFF.
Disconnect and inspect the PDM connectors and the associated inline connectors.
Repair:
corrosion (install new connector or terminals - clean module pins)
damaged or bent pins - install new terminals/pins
backed-out pins - install new pins as necessary
Reconnect the PDM connectors and the associated inline connectors. Make sure the connectors are fully seated and locked.
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 TSB exists for this concern, STOP this test and FOLLOW the TSB instructions. If no TSBs apply to this concern, INSTALL a new PDM. REFER TO: Passenger Door Module (PDM) (419-10 Multifunction Electronic Modules, Removal and Installation).
No
