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

System malfunction location	Vehicle collision determination system: Vehicle collision
Detection condition	• The PCM detects a vehicle collision based on the collision signal received from the Sophisticated Airbag Sensor (SAS) control module.
Fail-safe	• Refer to "DTC Table" and "Fail-safe Function Malfunction Contents Table". (See DTC TABLE [PCM (e-SKYACTIV)].)
Possible cause	• Vehicle is involved in collision (collision signal from Sophisticated Airbag Sensor (SAS) control module is received) • DTCs are stored in the Sophisticated Airbag Sensor (SAS) control module. • PCM malfunction

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION • Record the snapshot data. Note • Recording can be facilitated using the screen capture function of the PC.	—	Go to the next step.
2	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.
No	Go to the next step.
3	VERIFY SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE DTCs • 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 (TWO-STEP DEPLOYMENT CONTROL SYSTEM) (E)].)
No	Go to the next step.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED • 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. Warning • While performing this step, always operate the vehicle in a safe and lawful manner. • When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. ― Drive the vehicle under the snapshot data condition. • 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 [L.H.D. (E)].) (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].) 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.)
No	Go to the next step.
Repair completion verification 2	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.

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

• Record the snapshot data.

Note

• Recording can be facilitated using the screen capture function of the PC.

—

Go to the next step.

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 the next step.

VERIFY SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE DTCs

• 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 (TWO-STEP DEPLOYMENT CONTROL SYSTEM) (E)].)

Go to the next step.

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

• 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.

Warning

• While performing this step, always operate the vehicle in a safe and lawful manner.

• When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.

― Drive the vehicle under the snapshot data condition.

• 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 [L.H.D. (E)].)

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].)

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.)
