Continuing to calculate data of several sensor despite turning ignition OFF, when ignition turns ON, this enables PCM to be easy using calculated data.
If abnormal counterdown is detected for a calibratable time, PCM sets P2610. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
ITEM | Detecting Condition | Possible Cause | |
DTC Strategy | Case 1 | ● Compares the time elapsed recorded by the LPC against that recorded by the test timer | ● PCM |
Case 2 | ● Checks for abnormal resets of the LPC | ||
EnableCondition | Case 1 | ● Engine running 〉 10sec. ● Battery voltage 〉 8V | |
Case 2 | ● No Memory Failure Occurred | ||
Threshold | Case 1 | ● The difference between the Counter by the low power counter and the calibration the test timer clocks up 〉2sec. | |
Case 2 | ● The LPC is reset to zero abnormally | ||
Diagnosis Time | ● - | ||
MIL On Condition | ● 2 Driving Cycle | ||
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.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Has a problem been found?
▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
▶ 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.
There is a memory reset function on scantool that can erase optional parts automaticallydetected and memorized by PCM.
After a repair, it is essential to verify that the fault has been corrected.
Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.
Using a Scantool, Clear the DTCs
Operate the vehicle within conditions noted in the freeze frame data or enable conditions
Monitor that all rediness test have been verified as " Complete "
Are any DTCs present ?
▶ Go to the applicable troubleshoooting procedure.
▶ System is performing to specification at this time.
