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.
Pinpoint Test R: Abs Module Communication Concern With Advanced Driver Assistance System (ADAS): Notes
Refer to VEHICLE DYNAMIC SYSTEMS for schematic and connector information.
Normal Operation and Fault Conditions
With the ignition ON, the Advanced Driver Assistance System (ADAS) sends messages to the ABS module over the FD-CAN. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the Advanced Driver Assistance System (ADAS), REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U2017:68 | Control Module Software #2: Event Information | This DTC sets when the collision deceleration message from the CCM is sent too often or the duration of the message is too long. This is mostly likely caused by a network communication concern or an internal failure of the CCM. |
| ABS U2107:00 | Collision Mitigation By Braking: No Sub Type Information | This DTC sets when the collision deceleration message from the CCM is sent too often or the duration of the message is too long. This is mostly likely caused by a network communication concern or an internal failure of the CCM. |
| ABS U2107:68 | Collision Mitigation By Braking: Event Information | Sets when the ABS module detects the vehicle deceleration is implausibly high when compared to the vehicle deceleration requested by the CCM. This is most likely caused by an abrupt stop of the vehicle due to a collision, an extreme driving situation, a mechanical or electrical failure of the cruise control system or an internal failure of the ABS module. |
| ABS U2108:68 | Adaptive Cruise Control: Event Information | Sets when the ABS module detects the vehicle deceleration is implausibly high when compared to the vehicle deceleration requested by the CCM. This is most likely caused by an abrupt stop of the vehicle due to a collision, an extreme driving situation, a mechanical or electrical failure of the cruise control system or an internal failure of the ABS module. |

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.
