Pinpoint Test B : The Cruise Control Is Inoperative - With Adaptive Steering

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

B1 PERFORM A NETWORK TEST
- Ignition ON.
- Using a diagnostic scan tool, perform the a network test.
Does the SASM and SCCM communicate on the network?

Yes GO to B2

No REFER to: Communications Network .

B2 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 DTC Chart: Powertrain Control Module (PCM) . If SECM DTC B137F:11, B137F:17, B137F:2A, B137F:4A or C2003:11 was retrieved, GO to B4 If any other SECM DTCs were retrieved, REFER to: Adaptive Steering .

GO to B3

B3 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 BOO1 (stoplamp switch) and BOO2 (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 B4

No	GO to Pinpoint Test C

B4 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 6.2L or 6.8L, GO to B5 If equipped with 6.7L diesel, GO to B6

No If one or more cruise control switch selections do not display on the IPC message center, GO to B7

B5 MONITOR THE PCM (POWERTRAIN CONTROL MODULE) TR (TRANSMISSION RANGE) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view PCM PIDs.
- Monitor the PCMPID: TR.
- Place the shift selector in DRIVE.
Does the PID value agree with the TR selector lever position?

Yes GO to B8

No REFER to: External Controls .

B6 MONITOR THE TCM (TRANSMISSION CONTROL MODULE) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view TCM PIDs.
- Monitor the TCMPID: TR
- Place the shift selector in DRIVE.
Does the PID value agree with the TR selector lever position?

Yes GO to B9

No REFER to: External Controls .

B7 CHECK THE CRUISE CONTROL STEERING WHEEL SWITCH

Disconnect the cruise control steering wheel switch. REFER to: Steering Wheel Multifunction Switch .

While pressing the cruise control ON/OFF and RES/CNCL switch, measure:

Resistance Specification

Button Pressed	Resistance Range
Button not pressed	488-540 ohms
GAP-	57-63 ohms
GAP+	175-193 ohms

While pressing the cruise control SET+ and SET- switch, measure:

Positive Lead	Measurement / Action	Negative Lead
C2490-6 (component side)	Courtesy of FORD MOTOR COMPANY	C2490-5 (component side)

Resistance Specification

Button Pressed	Resistance Range
Button not pressed	488-540 ohms
SET+	175-193 ohms
SET-	57-63 ohms

Do the resistances fall between the specified ranges?

Yes	REPAIR the circuit in question.

No	INSTALL a new cruise control steering wheel switch. REFER to: Steering Wheel Multifunction Switch .

B8 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 service article instructions. If no service articles address this concern, Refer to PCM Guided Routine .

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.

B9 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 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.
