Lexus NX: Internal Control Module Software Incompatibility Not Programmed (U030051,U030057)
DESCRIPTION
- The forward recognition camera receives vehicle information (Conv/HV) from the hybrid vehicle control ECU via the CAN communication line.
- When the forward recognition camera is unable to determine the vehicle information (Conv/HV) from the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU, the forward recognition camera outputs U030051.
- When the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U030057.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U030051 | Internal Control Module Software Incompatibility Not Programmed | Once 3 seconds elapse after turning the power switch on (IG), the forward recognition camera is unable to determine the vehicle information (Conv/HV) based on the vehicle information (Conv/HV) sent from the ECM for approximately 3 seconds or more |
|
| U030057 | Internal Control Module Software Incompatibility Invalid/Incompatible Software Component | Once 3 seconds elapse after turning the power switch on (IG), the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU does not match the vehicle information stored by the forward recognition camera for approximately 1 second or more |
|
CAUTION / NOTICE / HINT
NOTICE:
- When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
-
If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.
HINT:
Forward recognition camera adjustment can be performed by using either "One Time Recognition" or "Sequential Recognition".

PROCEDURE
| 1. | CHECK FOR DTC (HYBRID CONTROL SYSTEM) |
(a) Check for DTCs.
Click here
HINT:
If the front camera system outputs U030051 or U030057, hybrid control system DTCs may also have been output. Check the hybrid control system first.
OK:
Hybrid control system DTCs are not output.

| 2. | CHECK FOR DTC (HEALTH CHECK) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: System Select / Health Check.
(e) Check for DTCs.
OK:
ECUs other than the forward recognition camera do not output specification information mismatch DTCs related to the hybrid vehicle control ECU.
| NG | | REPLACE HYBRID VEHICLE CONTROL ECU |

HINT:
- When the specification stored by the forward recognition camera and the vehicle specification do not match, there is a malfunction in the specification information stored by the forward recognition camera. Therefore, replace the forward recognition camera.
- When the specification stored by the forward recognition camera and the vehicle specification match, a hybrid vehicle control ECU with different specifications may be installed. Therefore, replace the hybrid vehicle control ECU.
| Result | Proceed to |
|---|---|
| Specification stored by the forward recognition camera and vehicle specification do not match | A |
| Specification stored by the forward recognition camera and vehicle specification match | B |
| A | | REPLACE FORWARD RECOGNITION CAMERA |
| B | | REPLACE HYBRID VEHICLE CONTROL ECU |
