DTC B10A2:00 [PCM (SKYACTIV-G)]

Note

•  To determine the malfunctioning part, proceed with the diagnostics from “Function Inspection Using M-MDS”.


Details On DTCs

DescriptionVehicle collision
Detection conditionDetermination conditions•  A collision signal from the Sophisticated Airbag Sensor (SAS) control module is received.
Preconditions•  Not applicable.
Drive cycle•  1
Self test type•  CMDTC self test
Sensor used•  PCM
Fail-safe function•  Stops fuel injection control •  Stops fuel pump control •  Stops ignition control •  Stops engine coolant fan control
Vehicle status when DTCs are output•  Stops fuel pump operation when ignition is switched ON •  Delays starter operation during cranking for maximum 1.2 s.
Possible cause•  Vehicle is involved in collision (collision signal from Sophisticated Airbag Sensor (SAS) control module is received) •  Sophisticated Airbag Sensor (SAS) control module malfunction •  PCM malfunction

System Wiring Diagram

•  Not applicable

Function Explanation (DTC Detection Outline)

•  During a collision, the Sophisticated Airbag Sensor (SAS) control module sends a collision signal to the PCM via the CAN signal. The PCM records a DTC by receiving a collision signal.

•  This DTC does not indicate a part malfunction. It indicates operation of fail-safe from safety assurance during a vehicle collision.

Repeatability Verification Procedure

1.  Switch the ignition ON and leave for 5 s or more.

2.  Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC.)

3.  After switching the ignition off, switch the ignition back ON and leave for 5 s or more.

4.  Using the M-MDS, display DTCs and verify that DTC U0151:00 is not displayed. (See DTC INSPECTION.)

StepInspectionResultsAction
1PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION •  Record the freeze frame data/snapshot data. Note •  Recording can be facilitated using the screen capture function of the PC.Go to the next step.
2PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY •  Verify related Service Bulletins, on-line repair information, or Service Information availability. •  Is any related Information available?YesPerform repair or diagnosis according to the available information. •  If the vehicle is not repaired, go to the next step.
NoGo to the next step.
3PURPOSE: VERIFY IF OPERATION IS NORMAL AFTER VEHICLE COLLISION •  Ask customer about vehicle collision experience. •  Has the vehicle in for servicing been involved in a collision in which the air bag is deployed?YesExplain to the customer that the DTC is recorded as a result of a vehicle collision. Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
NoGo to the next step.
4PURPOSE: VERIFY SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE DTC •  Perform the DTC inspection for the Sophisticated Airbag Sensor (SAS) control module. (See DTC INSPECTION.) •  Are any DTCs displayed?YesRepair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [SAS CONTROL MODULE (STANDARD DEPLOYMENT CONTROL SYSTEM)].) (See DTC TABLE [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].) Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
NoGo to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure

•  Step 1

•  Repair completion verification

―  Verify that the primary malfunction is resolved and there are no other malfunctions.

StepInspectionResultsAction
1PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ―  Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is the same Pending DTC present?YesRefer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (E))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))].)
NoGo to the next step.
Repair completion verificationPURPOSE: VERIFY IF OTHER DTCs DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Are any other DTCs displayed?YesRepair the malfunctioning location according to the applicable DTC troubleshooting.
NoDTC troubleshooting completed.
