DTC P0573: BRAKE SWITCH INPUT #2 SIGNAL MISSING
Monitor & Set Conditions
Brake switch input No. 2 signal is monitored with ignition on engine off, and with engine running. DTC may set if Engine Control Module (ECM) sees brake switch ON and PCM sees brake switch OFF for 3 seconds. Condition must be met 10 times for DTC to set.
- Brake Switch CCD BUS Signal Missing From PCM.
Repair brake switch input to PCM. If brake switch input is okay, replace and program PCM due to no CCD BUSS message. See appropriate REMOVAL, OVERHAUL & INSTALLATION article.
