SOURCE: starts and runs 3-5 seconds and shuts down

Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

SOURCE: P0601 diagnostic code what is

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.

Other PCM / ECM Codes: P0602, P0603, P0604, P0605, P0606, P0607, P0608, P0609, P0610.

Hope this help to solve it (remember rated this).

P0606
Control Module Internal Performance

P0601
Control Module Read Only Memory (ROM)
ECM, PCM
U0107
Throttle Actuator Control (TAC) Module Serial Data Circuit
ECM, PCM

The throttle actuator control (TAC) module and the powertrain control module (PCM) communicate using a dedicated serial data circuit. This serial data circuit is separate from any other serial data circuit on the vehicle. Accurate transmitting and receiving of serial data requires not only good circuit integrity but also adequate system voltage. This diagnostic monitors the accuracy of the serial data transmitted between the TAC module and the PCM. If the PCM detects a loss of data or invalid data, or if the throttle limit is exceeded while operating in the Reduced Engine Power mode, DTC U0107 sets.

Your best bet is going to be to take your vehicle to a GM dealer ! Cadillac , Buick

What is a code p0601 for a 2008 saturn vue


P0601 ENGINE CONTROL MODULE CHECKSUM ERROR


  • The nerve center of the fuel injection system is the engine control module (ECM)
  • The ECM constantly supervises the information from various sensors, and regulates the systems that start after vehicle performance.
  • The ECM is also empowered to control all the diagnostic functions of the system.
  • It can detect operational flaws and caution the driver through the Malfunction Indicator Lamp (MIL)
  • It also records and stores a Diagnostic Trouble Code (DTC) which detects the likely problem- making parts to help the technician while repairing.
  • In order to house the program information and the calibrations required for engine, trans-axle diagnostics operation an electrically erasable programmable read only memory (EEPROM) is used.
  • For detecting errors in the software the ECM uses a specially devised value known as the checksum.
  • The checksum (self explanatory) is a value that is the sum total of all the numbers in the software added together.
  • If the values recorded by the ECM and the checksum do not match then a checksum error is highlighted.
