DTC C0252: Active Brake Control Sensors Uncorrelated (Intrigue): Diagnosis

Perform DIAGNOSTIC SYSTEM CHECK under DIAGNOSIS & TESTING. Go to next step.
Turn ignition off. Install scan tool. Turn ignition on, engine off. Select ABS DTC display function. If scan tool displays any DTC other than DTC C0252, see DIAGNOSTIC TROUBLE CODE DEFINITIONS table under DIAGNOSIS & TESTING for diagnosis. If scan tool does not display any other DTCs, go to next step.
Using scan tool, clear DTCs. Perform DIAGNOSTIC TEST DRIVE . Using scan tool, select ABS DTC display function. If DTC resets, go to next step. If DTC does not reset, see DIAGNOSTIC AIDS .
Using scan tool, select VSES data list. Compare data to typical values located in VSES SCAN TOOL DATA LIST table. See VSES SCAN TOOL DATA LIST table. If all parameters are correct, see INTERMITTENTS & POOR CONNECTIONS under DIAGNOSIS & TESTING. If all parameters are not correct, go to next step.
Check wiring harness connectors for the following: EBCM, brake pressure sensor, steering angle sensor, yaw/lateral accelerometer sensor, left front wheel speed sensor, right front wheel speed sensor, left rear wheel speed sensor and right rear wheel speed sensor. If problem was found, repair as necessary. After repairs, go to next step. If problem was not found, see INTERMITTENTS & POOR CONNECTIONS under DIAGNOSIS & TESTING.
Reconnect previously disconnected components and connectors. Using scan tool, clear DTCs. If DTC does not reset, system is okay.
