P061B

DTC P061B INTERNAL CONTROL MODULE TORQUE CALCULATION PERFORMANCE

Component Location:

GENERAL DESCRIPTION
Checking torque control state and torque, torque calculation protect RAM. ROM, or ALU when the torque calculated inside of PCM is higher than actually required torque. This type of malfunction is very difficult to find, however if it happens, it influences safety a lot. Therefore, detecting and decreasing torque is strongly required.

DTC DESCRIPTION
If desired torque is calculated much higher than actual torque, PCM senses it and decreases desired torque. The causes of this error are abnormal operation of PCM (RAM,ROM, ALU errors) and hardware malfunction such that actual air flow enters the engine is more than the flow recognized by PCM.If actual check sum do not correspond with memory check sum, PCM sets P0618. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till 1 driving cycle.

DTC Detecting Condition:

TERMINAL AND CONNECTOR INSPECTION
1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?

YES: Repair as necessary and go to "Verification of Vehicle Repair" procedure

NO: Substitute with a known-good PCM and check for proper operation. If the problem is corrected,replace PCM and then go to "Verification of Vehicle Repair" procedure.

NOTE: There is a memory reset function on Scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others

VERIFICATION OF VEHICLE REPAIR
After a repair, it is essential to verify that the fault has been corrected.
1. Monitor and record the Freeze Frame Data for the Diagnostic Trouble Cod e(DTC) which has been diagnosed.
2. Using a Scantool, Clear the DTCs
3. Operate the vehicle within conditions noted in the freeze frame data or enable conditions
4. Monitor that all readiness tests have been verified as "Complete"
5. Are any DTCs present?

YES: Go to the applicable trouble shooting procedure.

NO: System is performing to specification at this time.
