Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Normal Operation and Fault Conditions
With the ignition ON, the IPMA sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within the specified time frame, the module sets a DTC. This can be due to an IPMA failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the IPMA, refer to the Network Message Chart in Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
On vehicles equipped with adaptive cruise control, the CCM communicates with the ABS module through the IPMA, the CCM and the IPMA communicate over a private CAN.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U0265:00 | Lost Communication with Image Processing Sensor A: No Sub Type Information | This DTC sets in the ABS module when the adaptive cruise control data message from the IPMA is missing for at least 5 seconds. |
| U0265:82 | Lost Communication with Image Processing Sensor A: Alive/Sequence Counter Incorrect/Not Updated | This DTC sets in the ABS module when the counter signal value in the adaptive cruise control data message from the IPMA does not increase. |
| U0265:83 | Lost Communication with Image Processing Sensor A: Value of Signal Protection Calculation Incorrect | This DTC sets in the ABS module when an invalid checksum value is received in the adaptive cruise control data message from the IPMA. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
