2007 - Brake, red triangle, orange circle, ABS lights, Check VSC, no loss of power
2007 TCH 210k. Brake, red triangle warning, orange circle warning and ABS lights and CHECK VSC SYSTEM message suddenly came on while on highway the other day. No loss of power to brakes (or to transmission). For several months, brakes have been oddly quickly intermittent (more/less grabby), but only when the brake pedal is lightly pressed while at light, in stop-and-go traffic, or slowly rolling to a stop. Otherwise they seem to function normally. OBD2 scanner reports no trouble codes. The only reading reported is OBD-II Calibration ID: 33380200 Calibration Verification Numbers (CVN): p
Toyota replaced the Brake Actuator Assembly 7 years ago as part of the "Warranty Enhancement." Any thoughts on what the problem could be? |

No thoughts whatsoever. It could be one of many dozens of things. "BRAKE" light strongly suggests a problem with the ABS system.
You're not getting any codes because there are multiple codes that can't be read by consumer-grade code readers. It needs professional-grade scanners. Additionally, I have encountered several Toyotas that absolutely refuse to have their codes read by anything but professional-grade stuff. I have no explanation for it, but I've encountered it about 10 times in 500 encounters. Either take it to the dealership or a shop with a professional-grade scanner. |

Unless you have an expensive code reader, there are dozens of codes you can't read. The more hybrid-specific they are, the worse.
Given the symptoms and the "BRAKE" light illumination, I wouldn't be surprised if the ABS actuator has given it up again. |
