Lexus ES: Internal Control Module Software Incompatibility Not Programmed (U030051)
DESCRIPTION
The forward recognition camera receives vehicle information from the hybrid vehicle control ECU via CAN communication.
DTC U030051 is stored when the vehicle information from the hybrid vehicle control ECU cannot be confirmed.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U030051 | Internal Control Module Software Incompatibility Not Programmed | The forward recognition camera cannot confirm the vehicle information from the hybrid vehicle control ECU. |
|
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 the forward recognition camera will not match the information from the vehicle. As a result, 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 DTCs |
(a) Check for DTCs of hybrid control system.
Powertrain > Hybrid Control > Trouble Codes| Result | Proceed to |
|---|---|
| DTCs are not output | A |
| DTCs are output | B |

| 2. | CHECK FOR DTCs (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.
(f) Turn the power switch off.
OK:
DTCs indicating a vehicle information mismatch with that of the hybrid vehicle control ECU are not output by any ECU other than the forward recognition camera.
| NG | | REPLACE HYBRID VEHICLE CONTROL ECU |

| 3. | READ VALUE USING TECHSTREAM |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG)
(c) Turn the Techstream on.
(d) Enter the following menus: Chassis / Front Recognition Camera / Data List.
(e) Read the Data List according to the display on the Techstream.
Chassis > Front Recognition Camera > Data List| Tester Display | Measurement Item | Range | Normal Condition | Diagnostic Note |
|---|---|---|---|---|
| HV Equipped Information | Vehicle information (conventional/hybrid) stored in forward recognition camera | Non-HV / HV | Non-HV: Conventional vehicle HV: Hybrid vehicle | - |
| Tester Display |

| HV Equipped Information |
HINT:
- If the vehicle information stored in the forward recognition camera is different from the actual vehicle specifications, the vehicle information stored in the forward recognition camera may be incorrect. Replace the forward recognition camera.
- If the vehicle information stored in the forward recognition camera matches the actual vehicle specifications, the installed hybrid vehicle control ECU is incompatible. Replace the hybrid vehicle control ECU.
| Result | Proceed to |
|---|---|
| Vehicle information stored in forward recognition camera and actual vehicle specifications do not match | A |
| Vehicle information stored in forward recognition camera and actual vehicle specifications match | B |
| A | | REPLACE FORWARD RECOGNITION CAMERA |
| B | | REPLACE HYBRID VEHICLE CONTROL ECU |
