Details On DTCs

System malfunction location

Vehicle collision determination system: Vehicle collision

Detection condition
Determination condition
• The PCM detects a vehicular collision from the collision signal received from the SAS control module.
Precondition
• Not applicable
Drive cycle
• 1
Self-test type
• CMDTC self-test
Sensor/unit used
• PCM
Fail-safe
• Stops the fuel injection control.
• Stops the fuel pump control.
• Stops the ignition control.
• Stops the engine coolant fan control.
• Performs vehicle speed restriction according to low battery voltage, and activates Auto P function at a vehicle speed of 5 km/h {3 mph} or less.
Vehicle status when DTCs are output
• Stops the fuel pump pre-operation when the ignition is switched ON.
• Delay in starter operation at cranking position (maximum 1.2 s)
Possible cause
• Vehicle is involved in collision (collision signal from SAS control module is received)
• SAS control module malfunction
• PCM malfunction

System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• During a collision, the SAS control module sends a collision signal to the PCM via the CAN signal. The PCM stores a DTC if it receives a collision signal.
• This DTC does not indicate a part malfunction. It indicates operation of failsafe from safety assurance during a vehicle collision.

Repeatability Verification Procedure

1. Switch the ignition ON and leave for 5 s.
2. Clear the DTC recorded in the memory using the M-MDS.(See: CLEARING DTC.)
3. Switch the ignition OFF, switch the ignition back ON, and leave for 5 s.
4. Using the M-MDS, verify that DTC U0151:00 is not displayed.(See: DTC INSPECTION.)

PID Item/Simulation Item Used In Diagnosis

Inspection

Results

Action

1
PURPOSE: VERIFY VALID REPAIR INFORMATION OR SERVICE INFORMATION
• Verify if there is valid servicing information.
• Is there valid servicing information?
Yes
Repair or perform diagnostics according to valid servicing information.
• If the malfunction is not resolved, go to the next step.
No
Go to the next step.
2
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.
3
PURPOSE: VERIFY IF SYMPTOM IS NORMAL OPERATION DUE TO 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 troubleshooting procedure to perform the procedure from Step 1.
No
Go to the next step.
4
PURPOSE: VERIFY SAS CONTROL MODULE DTCs
• Perform the DTC inspection for the SAS control module. (See DTC INSPECTION.)
• Is a DTC displayed?
Yes
Go to the applicable DTC inspection.
Go to the troubleshooting procedure to perform the procedure from Step 1.
No
Go to the troubleshooting 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.

Action

1
PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING LOCATION 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 DTC displayed?
Yes
Refer to the CAN (controller area network) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1 again.
• If the malfunction is not resolved, replace the PCM, then go to the next step. (Refer to [PCM REMOVAL/INSTALLATION] in workshop manual.)
No
Go to the next step.
Repair completion verification 1
PURPOSE: VERIFY IF OTHER DTCs OCCURRED SIMULTANOUSLY
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are other DTCs displayed?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
