Are any DTCs recorded?

Yes If ABS DTCs were retrieved, REFER to: Anti-Lock Brake System (ABS) and Stability Control .

No GO to B2

B2 PERFORM A NETWORK TEST
- Using a diagnostic scan tool, perform the a network test.
Does the SASM and SCCM communicate on the network?

Yes GO to B3

No REFER to: Exterior Lighting - System Operation and Component Description .

B3 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS)

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

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

Are any DTCs recorded?

Yes	If PCM DTCs were retrieved, REFER to the Master DTC Chart. If SECM DTC B137F:11, B137F:17, B137F:2A, B137F:4A or C2003:11 was retrieved, GO to B5 For all other SECM DTCs, REFER to: POWER STEERING .

GO to B4

B4 CHECK THE STOPLAMP SWITCH (BOO1) AND CRUISE CONTROL DEACTIVATOR SWITCH (BOO2) PARAMETER IDENTIFICATIONS (PIDS)

Using a diagnostic scan tool, view PCM PIDs.

Using the table, monitor the PIDs

Access the PCM and monitor the BOO1 (0) PID

(stoplamp switch) and

Access the PCM and monitor the BOO2 (0) PID

(cruise control deactivator switch) while applying and releasing the brake pedal.

Brake Pedal Position	BOO1 PID	BOO2 PID
Released	Off	Off
Applied	On	On

Do the PID values agree with the brake pedal position?

Yes

GO to B5

No	GO to Pinpoint Test C

B5 CHECK THE CRUISE CONTROL SWITCH
- Using a diagnostic scan tool, perform the SECM active test.
- Using the scan tool select and activate each cruise control switch while monitoring the IPC message center.
Does the message center agree with each switch selection?

Yes If equipped with 2.7L, 3.3L, 3.5L, or 5.0L engine, GO to B9 If equipped with 3.0L diesel engine, GO to B10

No If one or more cruise control switch selections do not display on the IPC message center, GO to B6

B6 CHECK THE CRUISE CONTROL STEERING WHEEL SWITCH

Ignition OFF.

Are the resistances greater than 10, 000 ohms?

Yes	INSTALL a new SECM. REFER to: Steering Wheel - Vehicles With: Adaptive Steering .

No	Install a new steering wheel. REFER to: Steering Wheel .

B9 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all PCM 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 PCM 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, refer to PCM GUIDED ROUTINE TESTING
Internet Explorer version 11 or greater is required to perform this Pinpoint Test.

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.

B10 CHECK FOR CORRECT TCM (TRANSMISSION CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all TCM 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 TCM 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 TCM. REFER to: Transmission Control Module (TCM) .

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.
