2GR-FE ENGINE CONTROL: SFI SYSTEM: P0504: Brake Switch "A" / "B" Correlation
P0504 - Brake Switch "A" / "B" Correlation
DESCRIPTION
The stop light switch assembly is a duplex system that transmits 2 signals: STP and ST1-. These 2 signals are used by the ECM to monitor whether
or not the brake system is working properly. If both signals, which indicate the brake pedal is being depressed or released, are detected
simultaneously, the ECM interprets this as a malfunction in the stop light switch assembly and sets the DTC.
HINT
The normal conditions are as shown in the table below. The signals can be read using the Techstream.
