What is internal control module memory checksum error?

What is internal control module memory checksum error?

Diagnostic trouble code (DTC) P0601 stands for “Internal Control Module Memory Checksum Error.” It is triggered when the powertrain control module (PCM) detects an internal problem, typically a failed Memory checksum test. The PCM’s Memory checksum test is performed regularly.

How do you reset the computer on a 2001 Dodge Ram 1500?

Turn the ignition to the start position for a count of 30 to 40 seconds. Turn it back off, then go back to Your battery, and replace the negative terminal to it’s original connection. The PCM should now be reset.

How do I reset my Dodge computer?

To reset the computer in your RAM 1500, take the following steps:

  1. Identify your battery’s negative cable.
  2. Disconnect the negative cable from the battery.
  3. Wait 20 minutes so that all systems have shut down.
  4. Reconnect the negative cable.

What does the p0601 code mean on a Dodge?

There is an internal error in the Powertrain Control Module (PCM) system. The P0601 is a common code with Dodge vehicles and the most common problem is the PCM. Erasing the codes may temporarily fix the problem.

What does it mean when your PCM says p0601?

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.

What causes p0601 on a CAN bus?

The number of possible causes of P0601 is almost directly proportional to the complexity of the CAN bus system. Nonetheless, some causes occur more often than others, with the following being the most likely- Damaged, burnt, shorted, or corroded wiring and connectors. Open circuits.

Which is the correct order to resolve p0601?

Therefore, always follow the rule that says codes must be diagnosed and repaired in the order in which they were stored. Thus, if code P0601 occurred first, it will be stored first, meaning that resolving P0601 will usually resolve all the other codes as well.
