P0572
DTC P0572CIRCUIT DESCRIPTION
The electronic brake control module (EBCM) receives a signal from the brake pedal position (BPP) sensor through the brake position sensor signal circuit. The EBCM then applies a signal through the torque converter clutch (TCC)/brake/cruise control release switch signal circuit to the transmission control module (TCM) and engine control module (ECM).
CONDITIONS FOR RUNNING THE DTC
- The vehicle has cycled from 0-60 km/h (0-37 mph) 3 times in 1 ignition cycle.
- Continuous once the previous criteria have been met.
CONDITIONS FOR SETTING THE DTC
The TCM detects voltage on the TCC/brake/cruise control release switch signal circuit when the circuit should be open.
ACTION TAKEN WHEN THE DTC SETS
- The TCM stores the DTC information into memory when the diagnostic runs and fails.
- The malfunction indicator lamp (MIL) will not illuminate.
- The TCM records the operating conditions at the time the diagnostic fails. The TCM stores this information in the Failure Records.
CONDITIONS FOR CLEARING THE DTC
- A last test failed, or current DTC, clears when the diagnostic runs and does not fail.
- A history DTC will clear after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
- Use a scan tool in order to clear the DTC.
TEST DESCRIPTION
Steps 1 - 6:
The number below refers to the step number on the diagnostic table.
2. This step determines if the fault is present.
