This is a generic trouble code that applies to all vehicles with the OBD-II system. When this code is stored, this means the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) has found an internal performance error with the EEPROM (electronically erasable read-only memory). You may also want to check chassis and engine ground junctions. In some cases, depending on the perceived severity of the problem, multiple failure cycles may be needed for the Check Engine light to activate. The TCM (transmission control module), TCSM (traction control module), and other controllers also interact with the EEPROM. The main chip of the indoor or outdoor PCB cannot receive feedback form the EEPROM chip. Cmd> reboot. 1. If the PCM sees discrepancies in the functionality of the EEPROM, it stores the Error Code P062F and activates the Check Engine light. We can use other dump and fix ISN with ECU,EGS but by this way, we need replace keys. Everything was working okay with the single MultiRotor it came with. Re-flashing of EEPROM using ConfigMagic. EEPROM ic is also called a non-volatile memory because when the power is switched off, the stored data (information) in the EEPROM ic will not be erased or corrupt and the data is still intact. Fixing Eeprom_qca9377_1p1_NFA425_olpc.bin Issues - How to Download and Repair. Data that cannot be automatically corrected (uncorrectable double-bit ECC errors) are left as all 1s in FlexRAM. The Internal Control Module monitoring processors are responsible for different controller self-test duties and overall internal control module accountability. No start condition 2. The EEPROM and new PCM will the need to be programmed as a unit. Eeproms, as far as I know, do not have this feature. If the error code comes back the indoor or outdoor PCB likely needs replaced.
