DTC P1630: Communication Error from VSC to ECM [12/2013 - 11/2016]: Description
WARNING: This page is about a different car, the 2016 Toyota Highlander, 2015 Toyota Highlander, and 2014 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
The skid control ECU (brake actuator assembly) sends signals such as cruise control cancel signals and brake demand response signals to the ECM when the dynamic radar cruise control system is operating.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P1630 | Communication Error from VSC to ECM | While the dynamic radar cruise control is either preparing for operation or operating, communication data from the skid control ECU (brake actuator assembly) is logically inconsistent for a certain amount of time, the ECM stores this DTC. |
