The EBCM/EBTCM opens an outlet valve for short periods in order to reduce pressure at the RR wheel.

CONDITIONS FOR SETTING THE DTC
The DTC C1252 sets when the EBCM/EBTCM detects an open or short to ground in the RR outlet valve circuit.

ACTION TAKEN WHEN THE DTC SETS
The following actions are taken when the DTC sets:
^ A malfunction DTC is stored
^ The ABS is disabled
^ The ANTILOCK indicator lamp is turned ON

CONDITIONS FOR CLEARING THE DTC
