Pinpoint Test Ca : U0199:00

CA1 VERIFY THE CUSTOMER CONCERN

Ignition ON.

Verify there is an observable symptom present.

Is an observable symptom present?

Yes

GO to CA2

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.

CA2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform the network test.
Does the DDM pass the network test?

Yes GO to CA3

No Refer to: Communications Network .

CA3 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Are any non-network Diagnostic Trouble Codes (DTCs) present?

Yes DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs). Refer to DTC Chart: Instrument Panel Cluster (IPC) .

No GO to CA4

CA4 PERFORM THE DDM (DRIVER DOOR MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the DDM self-test.
Are any non-network Diagnostic Trouble Codes (DTCs) present?

Yes Refer to: Locks, Latches and Entry Systems .

No GO to CA5

CA5 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)

Using a diagnostic scan tool, clear the IPC Diagnostic Trouble Codes (DTCs).

Ignition OFF.

Ignition ON.

Wait 10 seconds.

Using a diagnostic scan tool, perform the continuous memory self-test.

Check the IPC Diagnostic Trouble Codes (DTCs).

Is DTC U0199:00 still present?

Yes

GO to CA6

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.

CA6 CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN

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.

CHECK the vehicle service history for recent service actions related to the DDM, GWM or IPC. If recent service history is found:
- verify correct replacement module was installed
  - HVBOM may be used to verify correct part fitment
- verify the configuration of replacement module was correct
  - re-configure module using as-built data if prior configuration is suspect
- verify the module was not obtained from a like vehicle and installed into customer vehicle
  - return the swapped module to source vehicle and obtain new replacement module

Operate the system and determine if the observable symptom is still present.

Is the observable symptom still present?

Yes

GO to CA7

No	The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

CA7 CHECK FOR CORRECT DDM (DRIVER DOOR MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the DDM and all related in-line 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 DDM and all related in-line 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 TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new DDM. Refer to: Driver Door Module (DDM) .

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.
