P0616 Or P0617
- D1 CHECK THE PCM (POWERTRAIN CONTROL MODULE) STARTER RELAY CIRCUITS FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect PCM C1381B .
- Disconnect BJB starter relay.
- Ignition ON.
- Measure:
Positive Lead Measurement/Action Negative Lead C1381B-43 Ground C1381B-62 Ground
Is any voltage present?
- Yes : REPAIR the affected circuit.
- No : GO to D2
- D2 CHECK THE PCM (POWERTRAIN CONTROL MODULE) STARTER RELAY CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
- Measure:
Positive Lead Measurement/Action Negative Lead C1381B-43 Ground C1381B-62 Ground
Are the resistances greater than 10, 000 ohms?
- Yes : GO to D3
- No : REPAIR the affected circuit.
- D3 CHECK THE PCM (POWERTRAIN CONTROL MODULE) STARTER RELAY CIRCUITS FOR AN OPEN
- Measure:
Positive Lead Measurement/Action Negative Lead C1381B-43 BJB starter relay pin 1 C1381B-62 BJB starter relay pin 2
Are the resistances less than 3 ohms?
- Yes : GO to D4
- No : REPAIR the affected circuit.
- Measure:
- D4 CHECK BJB (BATTERY JUNCTION BOX) STARTER RELAY
- Ignition OFF.
- Connect PCM C1381B .
- Replace BJB starter relay with a known good relay
- Ignition ON.
- Using a diagnostic scan tool, perform the PCM self-test.
Is PCM Diagnostic Trouble Code (DTC) P0616 or P0617 still present?
- Yes : GO to D5
- No : INSTALL a new BJB starter relay.
- D5 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, INSTALL a new PCM
.
REFER to: POWERTRAIN CONTROL MODULE (PCM) - 2.0L EcoBoost (184kW/250PS) - MI4 .
- 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.
