DTC P0606: Powertrain Control Module (Pcm) Processor
P0606 - POWERTRAIN CONTROL MODULE (PCM) PROCESSOR
| Description: | P0606 indicates a register readback (PCM internal communications) error. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | For electronic throttle control (ETC) applications, an internal PCM concern, or an ETC system failure mode effect management (FMEM) condition exists. Diagnose other DTCs first. For all others, an internal PCM concern may be present. For both applications if only DTC P0606 is present, clear the DTCs. Repeat the self-test. Repair as necessary. If DTC P0606 is retrieved again, install a new PCM. Refer to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) . | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| Vehicles With Electronic Throttle Control (ETC) | The DTC is an indication of a failure mode in the electronic throttle control system, which includes the accelerator pedal position (APP) sensor, electronic throttle body (ETB), and PCM. It is accompanied by other DTCs which provide repair direction. Diagnose and repair those DTCs, and the DTC P0606 will not be reset. If only DTC P0606 is present, clear the DTCs. Repeat the self-test. If DTC P0606 is retrieved again, install a new PCM. Refer to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) . | ||
| All others | Reprogram or update the calibration. Check for other DTCs and diagnose those first. Make sure to check for aftermarket performance products before installing a new PCM. Clear the DTCs, repeat the self-test. If the DTC is retrieved again, install a new PCM. Refer to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) . | ||
