Need to reset ECM memory function

It isn't a fusible item, it is a function of the Engine Control Module. You need an auto electrician for issues and to diagnose faults.

2002 Toyota Camry 2.4L - ECM ECU PCM ' 89661-3T171

The ECM memory should have been reset due to which the calibration of the accelerator pedal has been erased. Use a scan tool and calibrate deceleration sensor. You can perform the calibration by clicking Engine and ECT - special function - and then
click "deceleration 0 point calibration" while doing that make sure that car IGN switch is "ON" and gear shift is on "P. Some automatic transmission DTCs cause the MIL to come on. If the MIL is on and no DTCs are indicated in the EFI system, select the A/T system, and check for automatic transmission DTCs.

Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.
This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem. If this code is present and the MIL (Malfunction Indicator Lamp) is illuminated that basically means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.

Symptoms Symptoms of a P0700 DTC may include:

• Malfunction Indicator Lamp (MIL) illumination
• The transmission may exhibit drivability problems like slipping, etc.

Causes More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).
Possible Solutions For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.
If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

If the problem persists, replace the ECM.

P0763 - Shift Solenoid C Electrical
Possible causes- Faulty shift solenoid C valve
- Shift solenoid C valve harness or connectors
- Shift solenoid C valve circuit is open or shorted
- Low transmission fluid level
- Dirty transmission fluid
When is the code detected?The P0763 code is detected when the gear required by the ECM does not match the actual gear when vehicle is driven.Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission will not shift gears.P0763 Description Shift solenoid valve C is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.

P1600 - Loss of KAM (Keep Alive ECM memory) Power; Open Circuit

Check all fuses related to the ECM

According with the repair guide, with automatic transmission...Transmission model A541E (17 bolt fluid pan): - Service change only - 3.7 quarts.
- Total refill - 8.5 quarts.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

for the p0500, the solution:
The simplest thing to do is to reset the code and see if it comes back.
i know this tool is helpful for your car.
Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly.
If the wiring and connectors are OK, then check the voltage at the speed sensor. Again, the exact procedure wil depend on your make and model of vehicle.
If everything looks OK, replace the sensor.

ECM memmory was reset on toyota estima 2008 model. Since then engine warning light and 4WD light come on. toyota scanner reads P1589 ACCELERATOR SENSOR LEARNING VALUE. can you assist

When you replace battery in 2002 Camry ECM tries to reset to factory levels. The reason it will not idle is that the throttle body is dirty and ECM thinks it should be new!! Clean throttle body with cleaner that is safe for tbs and this will fix your idle problem.

When all electrical power is removed, the car's computers are reset to a default mode. They have to 'relearn' your specific car's needs. Give it a couple of days and see if it doesn't recover. This goes for the transmission too -- it has to relearn shift points, so it may shift a little roughly for a day or two. If you still have the problem after a couple of days, have it checked to see if you have any error codes stored.
