Lexus ES: Hybrid/EV Powertrain Control Module Processor Unexpected Operation (P060694)
DTC SUMMARY
MALFUNCTION DESCRIPTION
The main CPU and sub CPU of the Hybrid vehicle control ECU monitor each other.
The cause of this malfunction may be the following:
- Hybrid vehicle control ECU malfunction
DESCRIPTION
The hybrid vehicle control ECU monitors its internal operation and will store these DTCs when it detects an internal malfunction.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P060694 | Hybrid/EV Powertrain Control Module Processor Unexpected Operation | The main CPU value received by the sub CPU of the hybrid vehicle control ECU exceeds the threshold for a certain period of time. (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.

- 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 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
-
Turn the power switch on (READY) and wait for 10 seconds or more. [*1]
HINT:
[*1] : Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
PROCEDURE
| 1. | CHECK DTC OUTPUT (HYBRID CONTROL) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
(d) Check for DTCs.
Powertrain > Hybrid Control > Trouble Codes| Result | Proceed to |
|---|---|
| P060694 only is output. | A |
| DTCs except P060694 are output. | B |
(e) Turn the power switch off.
