Toyota RAV4 Service Manual: Vehicle speed signal error (test mode dtc)

Toyota RAV4. Vehicle speed signal error (test mode dtc)


Description

The tire pressure warning ecu receives a speed signal from the combination meter. This dtc is stored upon entering test mode, and cleared when a vehicle speed signal of 12 mph (20 km/h) is detected for 3 seconds or more. The dtc is output only in test mode.
