Pinpoint Test C : The Cruise Control Does Not Disengage When The Clutch Pedal Is Pressed

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

C1 CHECK THE CPP (CLUTCH PEDAL POSITION) SWITCH (CPP_TOP) PARAMETER IDENTIFICATION (PID)
- Ignition ON.
- Using a diagnostic scan tool, view PCM Parameter Identifications (PIDs).
- Monitor the PCM Parameter Identification (PID) CPP_TOP while pressing and releasing the clutch pedal.
Does the Parameter Identification (PID) value read "YES" with the clutch pedal pressed?

Yes GO to C5

No GO to C2

C2 CHECK THE CPP (CLUTCH PEDAL POSITION) SWITCH

Ignition OFF.

Disconnect the CPP switch connector C277 .

Connect a fused jumper wire:

Ignition ON.

Using a diagnostic scan tool, monitor the PCM Parameter Identification (PID) CPP_TOP.

Does the Parameter Identification (PID) value read YES?

Yes	INSTALL a new CPP switch.

GO to C3

C3 CHECK THE CPP (CLUTCH PEDAL POSITION) SWITCH GROUND CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect CPP switch connector C277 .

Connect a fused jumper wire:

Positive Lead	Measurement / Action	Negative Lead

Ignition ON.

Using a diagnostic scan tool, monitor the PCM Parameter Identification (PID) CPP_TOP.

Does the Parameter Identification (PID) value read YES?

Yes	REPAIR the ground circuit.

GO to C4

C4 CHECK THE CPP (CLUTCH PEDAL POSITION) SWITCH SIGNAL CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect:
- On vehicles equipped with a 2.0L Duratec-HE engine disconnect PCM connector C175B
- On vehicles equipped with a 1.0L or 2.0L EcoBoost engine disconnect PCM connector C1381B
- On vehicles equipped with a 2.3L GTDI (RS) engine disconnect PCM connector C1926B

Measure:

Is the resistance less than 3 ohms?

Yes

GO to C5

No	REPAIR the circuit.

C5 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all PCM and 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 PCM and 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 the TSB instructions. If no TSB addresses this concern, Refer to PCM GUIDED ROUTINE TESTING

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.
