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
| Description | Vehicle collision | |
| Detection condition | Determination 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
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.)
PID Item/Simulation Item Used In Diagnosis
• Not applicable
Function Inspection Using M-MDS
| Step | Inspection | Results | Action |
| 1 | PURPOSE: 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. |
| 2 | PURPOSE: 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? | Yes | Perform repair or diagnosis according to the available information. • If the vehicle is not repaired, go to the next step. |
| No | Go to the next step. | ||
| 3 | PURPOSE: 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? | Yes | Explain 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. |
| No | Go to the next step. | ||
| 4 | PURPOSE: 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? | Yes | Repair 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. |
| No | Go 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.
| Step | Inspection | Results | Action |
| 1 | PURPOSE: 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? | Yes | Refer 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))].) |
| No | Go to the next step. | ||
| Repair completion verification | PURPOSE: VERIFY IF OTHER DTCs DISPLAYED • Perform the DTC inspection. (See DTC INSPECTION.) • Are any other DTCs displayed? | Yes | Repair the malfunctioning location according to the applicable DTC troubleshooting. |
| No | DTC troubleshooting completed. |
