DTC P0724: BRAKE SWITCH CIRCUIT HIGH INPUT
NOTE:For circuit identification, see CONNECTOR IDENTIFICATION and/or WIRING DIAGRAMS.
The brake switch is used to indicate brake pedal status to PCM. Normally closed brake switch supplies battery voltage to PCM. When brake pedal is applied, brake switch opens, interrupting voltage to PCM. When brake pedal is released, voltage is constant to PCM. When PCM sees zero volts at brake switch input, PCM de-energizes TCC solenoid. DTC P0724 will set when PCM detects a closed (stuck off) brake switch during deceleration.
Conditions For Running DTC
DTC will run under the following conditions:
Ignition is on.
System voltage is 8-18 volts.
Conditions For Setting DTC
DTC will set under the following conditions:
PCM detects a closed brake switch circuit (12 volts) during deceleration and following conditions occur 8 consecutive times: Vehicle speed is greater than 20 MPH for 6 seconds, then vehicle speed is 5-20 MPH for 3 seconds, then vehicle speed is less than 5 MPH.
