I ran a diagnostic on the car and it came back with the code. BRAKE SWITCH B CIRCUIT MALFUNCTION. I erased the code from the car, but it comes back. What do I need to do to fix this problem?
How do I correct the code P0703 on a 2002 Dodge Stratus?
The PCM monitors changes in input voltage from the brake switch. If the PCM does not detect PCM terminal 1AU voltage changes while alternately accelerating and decelerating 8 times, the PCM determines that brake switch circuit has malfunctioned.
• Brake switch malfunction
• Poor connection of brake switch connector or PCM connector
• Short to power supply in wiring harness between brake switch terminal D and PCM connector terminal 1AU
• Open circuit in wiring harness between brake switch terminal D and PCM connector terminal 1AU
• Open circuit in wiring harness between battery positive terminal and brake switch terminal A
• PCM malfunction
