Brake Switch Diagnostics
BRAKE SWITCH PLAUSIBILITY CHECKS
| DTCs | P0504 - Brake Switch "A"/"B" Correlation P0572 - Brake Switch "A" Circuit Low P0573 - Brake Switch "A" Circuit High |
| Monitor Execution | Continuous |
| Monitor Sequence | None |
| Sensors OK | |
| Monitoring Duration | Varies with driving conditions |
TYPICAL BRAKE SWITCH DIAGNOSTIC THRESHOLDS
| P0504 - Brake switches disagree (pressed/not pressed) for 40 braking events P0572 - No brake switch activation seen for 40 inferred braking events P0573 - Brake switch activation seen for 40 inferred acceleration events |
