DTC C1626 IMPLAUSIBLE CONTROL

COMPONENT LOCATION

Refer to DTC C1235. C1235

GENERAL DESCRIPTION

The pressure sensor, installed in the HECU, sense the brake oil pressure to judge driver's brake intention when ESC is operating. If pressure of master cylinder is applied to pressure sensor, the strain of the piezo element is changed and then the resistance of bridge circuit is changed according to changed strain. Therefore this changed resistance changes output voltage of bridge circuit and output voltage changes linearly. The sensor output is a analog signal in proportion to supply voltage, and the HECU recognizes a pressure value according to signal ratio about supply voltage.

DTC DESCRIPTION

Under normal conditions, the inlet valves of all four wheels are not closed during control for longer than 1.28s or If the controller requests pressure-hold or pressure-decrease for longer than 1.28s, a fault is detected. The ABS/ESC warning lamp is turned ON and the EBD warning lamp is turned OFF.

DTC DETECTING CONDITION:

COMPONENT INSPECTION

Refer to DTC C1235. C1235

VERIFICATION OF VEHICLE REPAIR

Refer to DTC C1101. C1101
