Computer software glitch. dealer may be able to reflash software. If not, will need new computer to resolve code. Is the car running OK?
If yes, you can try removing the negative battery terminal for a while to see if that will clear the code. Would hate to see you buy a computer module whith the car running fine.

Engine light is on. Runs fine. Getting a P0601 "Internal control module memory check sum error" What could cause this?


P0601 - Internal Control Module Memory Check Sum Error

Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.

Symptoms: Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

Causes: A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions: With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.


Hope this helps to solve it (remember to rate this answer).

Check engine light is on 3 codes p0740,p0601,& p0700 what do they mean


P0700 - Transaxle Control System Fault Conditions
The P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

P0740 - Torque Converter Clutch Circuit Malfunction

P0601 - Internal Control Module Memory Check Sum Error
