DTC Code |
DTC Detection Condition |
Trouble Area |
---|---|---|
C1452 |
After braking, the fluid pressure inside the accumulator is below the threshold within 3.2 seconds. |
|
CAUTION / NOTICE / HINT
NOTICE:
When replacing the skid control ECU (master cylinder solenoid), perform calibration (See page ).
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 ).
