Does the PID read No in both positions?
Yes GO to A6 No REFER to: Diagnostic Trouble Code (DTC) Charts and Pinpoint Tests - 2.0L EcoBoost (177kW/240PS) - MI4 . - A6 CHECK THE PCM (POWERTRAIN CONTROL MODULE) ENGINE CRANKING (ENG_CRANK) PID (PARAMETER IDENTIFICATION)
- Make sure the transmission is in PARK or NEUTRAL.
- Using a diagnostic scan tool, view the PCM Parameter Identifications (PIDs).
- Monitor the PCM PID ENG_CRANK while turning the ignition switch to the START position.
Does the PID change from Inactive to Active?
Yes GO to A7 No GO to A17 - A7 CHECK THE STARTER RELAY CONTROL OPERATIONNOTE: The following step uses a test light to simulate normal circuit loads. Use only the test light recommended in the Special Tools table at the beginning of this article. To avoid connector terminal damage, use the Flex Probe Kit for the test light probe connection to the vehicle. Do not use the test light probe directly on any connector.
- Remove the BJB starter relay.
- Measure:
Positive Lead Measurement / Action Negative Lead
BJB starter relay pin 2
BJB starter relay pin 1
- Make sure the transmission is in PARK or NEUTRAL.
- While holding the key in the START position, observe the test light.
Does the test light illuminate when the key is in the START position?
Yes GO to A8 No GO to A15 - A8 CHECK THE VOLTAGE TO THE STARTER RELAY
Is the voltage greater than 11 volts?
Yes GO to A9 No VERIFY the BJB fuse 84 (30A) is OK. If OK, REPAIR the circuit for an open. If not OK, REFER to the OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short. - A9 CHECK THE STARTER MOTOR OPERATION AT THE STARTER RELAY
- Ignition OFF.
- With the transmission in PARK or NEUTRAL, momentarily connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead
BJB starter relay pin 3
BJB starter relay pin 5
Did the starter engage and the engine crank?
Yes INSTALL a new starter relay. No GO to A10 - A10 CHECK THE BATTERY GROUND CABLES
Are the voltages greater than 11 volts?
Yes GO to A11 No CLEAN or INSTALL new negative battery cables as necessary. REFER to: Battery Cables - 2.0L EcoBoost (184kW/250PS) - MI4 . - A11 CHECK THE STARTER MOTOR GROUND
Is the voltage greater than 11 volts?
Yes GO to A12 No CLEAN the starter motor mounting flange and MAKE SURE the starter motor is correctly mounted. REFER to: Starter Motor . - A12 CHECK THE VOLTAGE TO THE STARTER MOTOR
Is the voltage greater than 11 volts?
Yes GO to A13 No INSTALL a new positive battery cable. REFER to: Battery Cables - 2.0L EcoBoost (184kW/250PS) - MI4 . - A13 CHECK THE STARTER MOTOR FOR CORRECT OPERATION
- Perform Starter Motor - Positive Circuit Test .
Was an obvious cause found?
Yes Correct the cause as necessary. No GO to A14 - A14 CHECK FOR START INPUT AT THE STARTER
- Connect BJB starter relay.
- Disconnect Starter solenoid C197A.
- While holding the key in the START position, measure:
Positive Lead Measurement / Action Negative Lead C197A-1 ("S" terminal) Ground
Is the voltage greater than 11 volts?
Yes CLEAN the starter solenoid "S" terminal and starter solenoid connector. CHECK the wiring and the starter motor for a loose or intermittent connection. No REPAIR the circuit for an open. - A15 CHECK THE PCM (POWERTRAIN CONTROL MODULE) STARTER RELAY CONTROL CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect PCM C1381B.
Are the resistances greater than 10, 000 ohms?
Yes GO to A16 No REPAIR the affected circuit. - A16 CHECK THE PCM (POWERTRAIN CONTROL MODULE) STARTER RELAY CONTROL CIRCUITS FOR AN OPEN
- Measure:
Positive Lead Measurement / Action Negative Lead C1381B-43 BJB starter relay pin 2 C1381B-62 BJB starter relay pin 1
Are the resistances less than 3 ohms?
Yes GO to A17 No REPAIR the affected circuit. - Measure:
- A17 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PCM connectors.
- Repair:
- corrosion (install new connectors 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address 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.
