ELECTRONICALLY CONTROLLED BRAKE SYSTEM
NOTICE:
When replacing the brake booster with master cylinder (skid control ECU), sensor, etc., make sure that the power switch is turned off, the stop light switch is off, and 2 minutes have elapsed since the driver's door was closed.
HINT:
If no abnormality is found when inspecting parts, inspect the skid control ECU and ground points for poor connections.
When 2 or more DTCs are detected, perform circuit inspections one by one until the problem is identified.
Inspect the fuses and relays before inspecting the trouble areas as shown in the table below.
