2010 Cadillac Truck Escalade RWD V8-6.0L Hybrid Page 966
C0201 04 or C120D
* The EBCM detects an open in the circuits to the solenoid valve relay.
* The EBCM detects a stuck open solenoid valve relay.
C0201 0E or C120D
* The EBCM detects an short to battery in the circuits to the solenoid valve relay.
* The EBCM detects a stuck closed solenoid valve relay.
Action Taken When the DTC Sets
* The EBCM disables the antilock brake system (ABS) and the vehicle stability enhancement system for the duration of the ignition cycle.
* A driver information center message and/or a warning indicator may be displayed.
Conditions for Clearing the DTC
* The condition for setting the DTC is no longer present.
* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the EBCM.
2. Test for less than 1 ohm between the ground circuits listed below and ground.
* Terminal 13
* Terminal 38
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, verify that a test lamp illuminates between the B+ circuits listed below and ground.
* Terminal 1
* Terminal 25
瀚慖f the test lamp does not illuminate, test the appropriate circuit for a short to ground or an open/high resistance. If the circuit tests normal
and the B+ circuit fuse is open, replace the brake pressure modulator valve assembly.
4. If all circuits test normal, replace the EBCM and verify DTC does not reset. If the DTC resets, replace the brake pressure modulator valve
assembly.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
