P061B

DTC P061B






GENERAL DESCRIPTION
Checking torque control state and torque, PCM provides protection against RAM, ROM of ALU corruption causing the desired torque to be erroneously higher than actually desired. 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 the calculated torque is much higher than the desired torque, PCM sets P061B. MIL(Malfunction Indication Lamp) turns on.

DTC Detecting Condition:

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 Code(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 test have been verified as "Complete".
5. Are any DTCs present?

YES - Go to the applicable troubleshooting procedure.

NO - System is performing to specification at this time.
