Lexus NX: Internal Control Module EEPROM Error (P062F-143,P062F-165)
DESCRIPTION
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P062F-143 | Internal Control Module EEPROM Error | ECU internal malfunction (EEPROM error) (1 trip detection logic) | Hybrid vehicle control ECU | Comes on | Master Warning Light: Comes on |
| P062F-165 | Internal Control Module EEPROM Error | ECU internal malfunction (EEPROM error) (1 trip detection logic) | Hybrid vehicle control ECU | Comes on | Master Warning Light: Comes on |
MONITOR DESCRIPTION
The hybrid vehicle control ECU monitors its internal operation. If the internal operation is malfunctioning, the hybrid vehicle control ECU illuminates the MIL and stores a DTC.
MONITOR STRATEGY
| Related DTCs | P062F (INF 143): Internal control module EEPROM P062F (INF 165): Internal control module EEPROM for battery data |
| Required sensors/components | Hybrid vehicle control ECU |
| Frequency of operation | Continuous |
| Duration | TMC's intellectual property |
| MIL operation | 1 driving cycle / Immediately |
| Sequence of operation | None |
TYPICAL ENABLING CONDITIONS
| The monitor will run whenever the following DTCs are not stored | TMC's intellectual property |
| Other conditions belong to TMC's intellectual property | - |
TYPICAL MALFUNCTION THRESHOLDS
| TMC's intellectual property | - |
COMPONENT OPERATING RANGE
| Hybrid vehicle control ECU | DTC P062F (INF 143/165) is not detected |
CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 30 seconds or more.
- Turn the power switch on (IG) and wait for 15 seconds or more, turn the power switch off. [A]
- Repeat [A] 3 times. [B]
- Turn the power switch on (IG) and turn the Techstream on.
- Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. [C]
-
Read the current DTCs.
HINT:
- If a current DTC is output, the system is malfunctioning.
- If current DTCs are not output, perform the following steps to check for permanent DTCs.
- Check that the permanent DTCs are cleared.
- If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.
CAUTION / NOTICE / HINT
NOTICE:
There is a possibility that the DTC P062F is issued from the ECUs of the ECM and hybrid vehicle control ECU. Use Techstream to conduct a health check to confirm which ECU the DTC is issued from and then inspect the related system.
HINT:
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
- Turn the power switch off and wait for 30 seconds or more.
- Turn the power switch on (IG) and wait for 15 seconds or more.
