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 performed.

M1 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform a network test.
Does the DSM pass the network test?

Yes GO to M2

No DIAGNOSE no communication with the DSM. REFER to: Communications Network .

M2 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 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 K . For DTC U3006:17, U3007:17, U3013:17 or U3014:17, GO to Pinpoint Test L

GO to M3

M3 RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE DSM (DRIVER FRONT SEAT MODULE)
- Using a diagnostic scan tool, perform the DSM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?

Yes REFER to: SEATING SYSTEM - FRONT (1 OF 2) or SEATING SYSTEM - FRONT (2 OF 2) .

No GO to M4

M4 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 U0208:87 still present?

Yes

GO to M5

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.

M5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0208:87 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 U0208:87 set in other modules?

Yes GO to M6

No GO to M7

M6 CHECK FOR CORRECT DSM (DRIVER FRONT SEAT MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all DSM electrical connection(s) (harness side connectors and module terminals).

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 DSM electrical connection(s). 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 DSM. REFER to: Driver Front Seat Module (DSM) .

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.

M7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all BCM electrical connection(s) (harness side connectors and module terminals).

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 electrical connection(s). Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes
