Pinpoint Test B: Shift Solenoid B

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

B1 READ AND RECORD ALL DTCS
- Connect the scan tool.
- Read and record all DTCs.
Were DTCs P0755, P0758, P0976 and/or P0977 set?
- Yes : For DTCs P0755 and P0758, GO to B2 .
  For DTC P0976, GO to B4.
  
  For DTC P0977, GO to B6.
- No : GO to SYMPTOM CHART .

B2 CHECK THE SSB CIRCUIT FOR AN OPEN

Ignition OFF.
Disconnect: Transmission Vehicle Harness C168 .
Disconnect: PCM C175T .
Inspect the connectors for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.

Measure the resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C168-16	CET06 (GN/BN)	C175T-43	CET06 (GN/BN)

Is the resistance less than 5 ohms?

Yes : GO to B3 .
No : REPAIR the circuit. CLEAR the DTCs.

B3 CHECK THE SSB FOR AN OPEN

Measure the component side resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
16	-	15	-

Is the resistance between 4.0 and 7.2 ohms?

Yes : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS . PROGRAM the PCM with the latest calibration level. PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD . PERFORM the Solenoid Body Strategy Drive Cycle, REFER to SOLENOID BODY STRATEGY DRIVE CYCLE .
No : REMOVE the main control cover. REFER to MAIN CONTROL COVER . INSPECT the solenoid body for metal shavings on the exposed metal contacts or other components. CLEAN the solenoid body and RECHECK the resistance value. If the resistance value is out of specification and a short to ground is not found, INSTALL a new solenoid body assembly. REFER to SOLENOID BODY ASSEMBLY . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD . PERFORM the Solenoid Body Strategy Drive Cycle, REFER to SOLENOID BODY STRATEGY DRIVE CYCLE .

B4 CHECK THE SSB CIRCUIT FOR A SHORT TO GROUND

Ignition OFF.
Disconnect: Transmission Vehicle Harness C168 .
Disconnect: PCM C175T .
Inspect the connectors for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.

Measure the resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C168-16	CET06 (GN/BN)	-	Ground

Is the resistance greater than 10, 000 ohms?

Yes : GO to B5 .
No : REPAIR the circuit. CLEAR the DTCs.

B5 CHECK THE SSB FOR A SHORT TO GROUND

Measure the component side resistance between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
16	-	-	Ground

Is the resistance less than 5 ohms?

Yes : REMOVE the main control cover. REFER to MAIN CONTROL COVER . INSPECT the solenoid body for foreign material such as metal shavings on the exposed metal contacts or other components. CLEAN the solenoid body and RECHECK the resistance value. If the resistance value is out of specification and a short to ground is not found, INSTALL a new solenoid body assembly. REFER to SOLENOID BODY ASSEMBLY . PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD . PERFORM the Solenoid Body Strategy Drive Cycle, REFER to SOLENOID BODY STRATEGY DRIVE CYCLE .
No : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS . PROGRAM the PCM with the latest calibration level. PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD . PERFORM the Solenoid Body Strategy Drive Cycle, REFER to SOLENOID BODY STRATEGY DRIVE CYCLE .

B6 CHECK THE SSB CIRCUIT FOR A SHORT TO VOLTAGE

Ignition OFF.
Disconnect: Transmission Vehicle Harness C168 .
Disconnect: PCM C175T .
Inspect the connectors for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.
Ignition ON.

Measure the voltage between:

Positive Lead		Negative Lead
Pin	Circuit	Pin	Circuit
C168-16	CET06 (GN/BN)	-	Ground

Is any voltage present?

Yes : REPAIR the circuit. CLEAR the DTCs.
No : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS . PROGRAM the PCM with the latest calibration level. PERFORM the Solenoid Body Strategy Data Download procedure. REFER to SOLENOID BODY STRATEGY DOWNLOAD . PERFORM the Solenoid Body Strategy Drive Cycle, REFER to SOLENOID BODY STRATEGY DRIVE CYCLE .
