CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Check the condition of each related circuit connector before troubleshooting (See page ).
PROCEDURE
1. |
CHECK FOR DTC (CAN COMMUNICATION SYSTEM AND BRAKE CONTROL SYSTEM) |
(a) Check if the CAN communication system DTC is output (See page ).
(b) Start the engine.
(c) Drive the vehicle, accelerate to a speed of 3 km/h (2 mph) or more, and check if the speed sensor DTC (brake control system DTC) is output (See page ).
