The booster travel sensor provides the ABS module with an analog signal indicating the position of the diaphragm inside the brake booster. The ABS module supplies a 5-volt reference voltage to the sensor and ground. The ABS module receives a varying voltage proportional to the position of the diaphragm inside the brake booster. The ABS module monitors the brake booster travel sensor circuits for circuit faults. The ABS module compares the brake booster travel sensor signal with other brake system inputs to verify that the brake booster travel sensor signal is accurate. If a brake booster travel sensor circuit or signal fault is detected, the red brake warning indicator illuminates.
DTC DESCRIPTION TABLE
| DTC Description | Fault Trigger Conditions |
|---|---|
|
If circuit VCB34 (WH/BU) is open or shorted to ground or if the ABS module is faulted internally, this DTC sets. |
|
If the circuit is open, or if the ABS module is faulted internally, this DTC sets. |
|
This DTC can set if the booster travel sensor is improperly mounted, if the booster travel sensor is faulted internally or if the ABS module is faulted internally. This DTC can also set as a result of other brake booster travel sensor faults. All other brake booster travel sensor DTCs should be diagnosed prior to diagnosing DTC C0048:64. |
|
This DTC is set if the brake booster travel sensor supply circuit is shorted ground, if the booster travel sensor is shorted internally or if the ABS module is faulted internally. |
|
This DTC is set if the brake booster travel sensor supply circuit is shorted voltage, if the booster travel sensor is shorted internally or if the ABS module is faulted internally. |
|
This DTC can set as a result of other brake booster travel sensor circuit faults or if the ABS module is faulted internally. All other booster travel sensor DTCs should be diagnosed prior to diagnosing DTC C1108:1C. |
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Booster travel sensor
- ABS module
