id010239809000

Diagnostic procedure

DTC P0571

Brake switch circuit problem

DETECTION 

CONDITION

• The PCM monitors the change in the input voltage for brake switch No.1 and No.2. If the PCM detects that 

both brake switches No.1 and No.2 remain on or off for 15 s, it determines that the brake switch circuit has 
a malfunction.

Diagnostic support note

• This is a continuous monitor (Other).

• The MIL does not illuminate.

• FREEZE FRAME DATA is not available.

• DTCs are stored in PCM memory.

POSSIBLE 

CAUSE

• Brake switch malfunction

• Open circuit between brake switch terminal A and PCM terminal 1AF

• Open circuit between brake switch terminal C and body ground

• Short to the power between brake switch terminal A and PCM terminal 1AF

• Short to the ground circuit between brake switch terminal A and PCM terminal 1AF

• PCM malfunction

STEP

Yes

Go to the next step.

No

Record FREEZE FRAME DATA on the repair, then go to the 
next step.

2

VERIFY RELATED REPAIR INFORMATION 
AVAILABILITY

• Check for related Service Bulletins and/or on-

line repair information availability.

• Is any related repair information available?

Yes

Perform the repair or diagnosis according to the available 
repair information.

• If the vehicle is not repaired, go to the next step.
