Irakli Posted February 14, 2021 Report Share Posted February 14, 2021 I have C max hybrid 2013 energi flowing errors came out : Code: P0A0A:13-AF - High Voltage System Interlock Circuit A Code: P1A10:00-AF - Hybrid Powertrain Control Module - Battery Disabled Code: P0B37:00-26 - High Voltage Service Disconnect Open The car does not want to crank and start engine. Can you please advise where the problem might be? 12V Battery and High Voltage Fuse are tested and they works fine. Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted February 14, 2021 Report Share Posted February 14, 2021 (edited) Try reseating the HVB disconnect plug. It looks like the BECM believes the disconnect to the HVB is open but the disconnect is plugged in. With FORScan.org App you can run a self test on the BECM and other modules. Other than that you'll need a SM with wiring diagrams to run through wiring checks for shorts, grounds, open circuits and connector issues. ICE will not crank (not start) without the software having assurance that the HVB is connected and functional as MG1 (the generator in the hybrid transmission) using HV power from the HVB acts as starter motor to turn ICE. POB37 is the indication of HVB not functional and perhaps P0A0A is where the issue causing P0B37 is. P1A10 is simply the global DTC that the HVB has been disabled. P0A0A:13, P0A0C:00, P1A0F:68, P0B37:00 Refer to Wiring Diagrams Cell 12 for schematic and connector information. Normal Operation and Fault Conditions The SOBDMC incorporates two hardwired interlock circuit inputs. One is used to monitor the ACCM high voltage cable and the other is part of the high voltage fuse cover. The High Voltage battery incorporates one hardwired interlock circuit which is part of the service disconnect and is monitored by the BECM . The interlock circuit status from each module is sent over the HS-CAN . A P0A0A:13 will result from a faulty inerlock circuit at the SOBDMC or faulty interlock circuit at the High Voltage Battery. This fault will illuminate the stop safely hazard (red triangle) warning indicator and shut down the vehicle. Battery Pack Contactor malfunction thresholds: P0AA4 - Negative contactor status remains closed. • Negative Contactor Measurement is > 90% Negative Half Pack voltage AND • Negative Contactor Measurement is < 110% Negative Half Pack voltage AND • Negative Contactor Measurement is > 30 volts. P0AA5 - Negative contactor is commanded closed AND there is power to the contactor AND the contactor state is determined open. Open is defined as NOT closed (i.e. mutually exclusive). Closed is defined above: P0AA2 - Positive contactor is commanded closed AND there is power to the contactor AND the contactor state is determined open. Open is defined as NOT closed (i.e. mutually exclusive). Closed is defined as: • Negative Contactor Measurement is > 90% Negative Half Pack voltage AND • Positive Contactor Measurement is < 110% Positive Half Pack voltage AND • Positive Contactor Measurement is > 30 volts P0B37 - The interlock and disconnect are mechanically interconnected such that removing the disconnect opens the interlock. Interlock status is reported open for the following criteria: PSR OR Charge wakeup is High, ACL latch is reported tripped by low level driver and interlock is reported open by low level driver. (ACL is anti-chatter latch). P0B37:00; P0A0C:00 Refer to Wiring Diagrams Cell 12 for schematic and connector information. Normal Operation and Fault Conditions The BECM montiors the interlock circuit loop which travels in series through the service disconnect plug connection and the PTC heater high voltage cables for going open. If an open exists there will be no power to the high voltage contactor control windings which prevents them from closing. This is a safety feature which is used to verify the high voltage connections are not disconnected or removed. The service disconnect plug also shuts off the high voltage to the system so service to the system can be completed safely. When the service disconnect plug or PTC heater interlock circuits are open, the stop safely hazard (red triangle) warning indicator is illuminated and the vehicle will shut down and/or not start. DTC Description Fault Trigger Conditions P0B37:00 High Voltage Service Disconnect Open: No Sub Type Information This DTC is set in the BECM when the service disconnect is open for 1 second or more while the service disconnect plug is still inserted in the High Voltage Battery. P0A0C:00 High Voltage System Interlock Circuit Low: No Sub Type Information Sets when BECM senses the interlock circuit is low for 5 seconds or more. Possible Sources Service disconnect plug Wiring, terminals or connectors BECM PINPOINT TEST AE : P0B37:00, P0A0C:00 Edited February 14, 2021 by plus 3 golfer Quote Link to comment Share on other sites More sharing options...
fordfiestaa Posted March 13, 2021 Report Share Posted March 13, 2021 me too When the service disconnect plug or PTC heater interlock circuits are open, the stop safely hazard (red triangle) warning indicator is illuminated and the vehicle will shut down and/or not start.

shapeitup Posted March 8, 2022 Report Share Posted March 8, 2022 Hello, I'm having similar issues with a car that won't crank, start, or move. Same DTC's. Any solution on this one? Quote Link to comment Share on other sites More sharing options...
1myway1 Posted April 9, 2022 Report Share Posted April 9, 2022 (edited) Hello I need Hybrid Plugin chargers cover door, I have port, but need that rubber or plastic ring, which is lighting,, blinking what is name of this part? How I can searhc it, or where? can someone help? do ford fusion charging port parts same? My is ford c max energi 2013 I need this item (dm5z58405a26b) and this is entire port - dm5z10370d - but I need only blinking "ring", if it's possible find just it and not bye entire port )) Edited April 9, 2022 by 1myway1 Quote Link to comment Share on other sites More sharing options...
SPWj Posted May 4, 2022 Report Share Posted May 4, 2022 (edited) 2013 Ford C-max energi Current mileage – 63,475 Diagnostic Report 2022-05-03 141553.html 1. Service engine light on 2. Service wrench light on -- Powertrain or High voltage charge system fault detected. P0D59 BECM-B+EnergyCtrl ($7E4) Proximity Detection Circuit High 3. Vehicle Plug in light on -- Message asked is the vehicle plugged in, after answering NO, message comes back again and again. 4. At this point the green car ready light will not be on, and the car cannot be driven. 5. If you turn off and lock the car and come back 30 minutes later, then unlock the car, the Service engine light will be on and the green car ready to drive light will be on and you can drive off with just the service engine light on. 6. Sometimes the Service engine light will go off by itself and you will go for a few days without any problem. 7. Then the original Service engine, wrench, and Vehicle Plug in light on situation comes back. 8. Sometimes if the passenger door is opened and closed you can get to the point of the Service engine light on and the green ready to drive light on and you can drive off again. 9. If have attached two Diagnostic Reports Has anyone had this issue and a fix? Very Best spwj Edited May 4, 2022 by SPWj Add data Quote Link to comment Share on other sites More sharing options...
