).
PROCEDURE
1. |
CUSTOMER PROBLEM ANALYSIS |
(a) Check with the customer to determine if frequent braking has been performed.
|
2. |
RECONFIRM DTC |
(a) Clear the DTC (See page ).
(b) Turn the ignition switch off.
(c) Depress the brake pedal more than 40 times.
(d) Turn the ignition switch to ON.
(e) Wait for 99 seconds.
(f) Check if the same DTC is output (See page
).

---|---|
DTC is output |
A |
Frequent braking was not performed and DTC is not output |
B |
Frequent braking was performed and DTC is not output |
C |
HINT:
Excessive brake pedal operation results in abnormal accumulator pressure consumption. This is normal.
