Are any DTCs recorded?

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

No GO to A2

A2 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS)

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

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

Are any DTCs recorded?

Yes	If PCM DTCs were retrieved, REFER to the Master DTC Chart. If SCCM DTCs B137F:09, B137F:11 or B137F:17 were retrieved, GO to A4 For all other SCCM DTCs, REFER to: Steering Wheel and Column Electrical Components .

GO to A3

A3 CHECK THE STOPLAMP SWITCH (BOO1) AND CRUISE CONTROL DEACTIVATOR SWITCH (BOO2) PARAMETER IDENTIFCATIONS (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 A4

No	GO to Pinpoint Test C

A4 CHECK THE CRUISE CONTROL SWITCH PID (PARAMETER IDENTIFICATION)

Using a diagnostic scan tool,
Access the SCCM and monitor the SC_ONOFF (0) PID,

Access the SCCM and monitor the SC_CNCL_RESM (0) PID,

Access the SCCM and monitor the SC_SET+ (0) PIDand

Access the SCCM and monitor the SC_SET- (0) PID

Using the table, press each cruise control switch while monitoring the cruise control switch PID.

Cruise Control Switch	PID Value
ON (pressed/released)	On/Off
OFF (pressed/released)	On/Off
RES (pressed/released)	On/Off
CNCL (pressed/released)	On/Off
SET + (pressed/released)	On/Off
SET - (pressed/released)	On/Off

Does the PID value agree with the switch position?

Yes	If equipped with 2.7L, 3.3L, 3.5L, or 5.0L engine, GO to A10 If equipped with 3.0L diesel engine, GO to A11

No	If only one switch does not display the correct PID value, INSTALL a new LH steering wheel switch. REFER to: Steering Wheel Multifunction Switch . If multiple switches do not display the correct PID value, GO to A5

A5 CHECK FOR VOLTAGE TO THE CRUISE CONTROL SWITCHES

Ignition OFF.

Remove the driver airbag. REFER to: Driver Airbag .

Disconnect LH Steering Wheel Switch C2998.

Ignition ON.

Is the voltage approximately 5 volts?

Yes	TURN the ignition off and WAIT one minute. INSTALL a new LH steering wheel switch. REFER to: Steering Column Multifunction Switch LH . INSTALL the driver airbag. REFER to: Driver Airbag .

GO to A6

A6 CHECK THE STEERING WHEEL SWITCH HARNESS FOR AN OPEN

Ignition OFF.

Disconnect Clockspring C218B.

Are the resistances greater than 10, 000 ohms?

Yes

GO to A8

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

A8 CHECK THE STEERING WHEEL SWITCH CIRCUITS THROUGH THE CLOCKSPRING FOR AN OPEN

Disconnect Clockspring C218G from SCCM.

A9 CHECK FOR CORRECT SCCM (STEERING COLUMN CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all SCCM 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 SCCM 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 SCCM. REFER to: Steering Column Control Module (SCCM) .

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.

A10 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
