In Dodge/Chrysler products, a P0601 Buick trouble code means that a serial communication failed inside the computer at least 6 times.

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

Possible causes of OBD code P0601 Buick
A code P0601 Buick 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 Buick 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.
