DTC C0201
Diagnostic Instructions
DTC Descriptor
DTC C0201 00: Pump Motor Fuse Circuit Failure
Circuit/System Description
The pump motor fuse, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids.
Conditions for Running the DTC
| • | Ignition voltage is greater than 8 volts. |
Conditions for Setting the DTC
Pump motor supply voltage is less than 4 volts.
Action Taken When the DTC Sets
| • | The EBCM disables the antilock brake system (ABS)/traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition cycle. |
| • | ABS warning indicator turns ON. |
Conditions for Clearing the DTC
| • | The condition for setting the DTC is no longer present. |
| • | The EBCM automatically clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles. |
| • | The DTC can be cleared using a scan tool. |

Circuit/System Verification
- Ignition OFF, disconnect the harness connector at the EBCM.
- Test for less than 1 ohm between the ground circuit terminals listed below and ground.
| ⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
- Ignition ON, verify that a test lamp illuminates between B+ circuit terminals listed below and ground.
| ⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
- If all circuits test normal, replace the EBCM.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
