Test NTC-19: Checking Brake Switch Sense

NOTE: Possible causes are: ground circuit open, PCM connector failure, brake switch defective, brake switch sense circuit open, brake switch sense circuit short to ground or PCM defective.
  1. Turn ignition off. Disconnect brake switch connector. Inspect electrical connector and clean/repair as necessary. Turn ignition on. Using a DVOM, check voltage of brake switch sense circuit at brake switch connector (White/Red wire). If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, go to step 4.
  2. Connect a jumper wire between brake switch connector brake switch sense circuit (White/Red wire) and chassis ground. Turn ignition on with engine off. Using scan tool, read brake switch input status. If scan tool displays RELEASED, go to next step. If scan tool does not display RELEASED, repair open ground circuit. Perform TEST VER-4A: SPEED CONTROL VERIFICATION  .
  3. If no other potential causes are remaining, brake switch is assumed to be defective. Replace brake switch. Perform TEST VER-4A: SPEED CONTROL VERIFICATION  .
  4. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector C2 (located nearest to rear of vehicle). PCM is located to left of Power Distribution Center (PDC) in engine compartment. Inspect electrical connectors and clean/repair as necessary. Inspect PCM connector for corroded, damaged, pushed out or miswired terminals. If connector is okay, go to next step. If connector is not okay, repair as necessary. Perform TEST VER-4A: SPEED CONTROL VERIFICATION  .
  5. Using a DVOM, check resistance of brake switch sense circuit between PCM connector C2 terminal No. 62 (White/Red wire) and chassis ground. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair brake switch sense circuit short to ground. Perform TEST VER-4A: SPEED CONTROL VERIFICATION  .
  6. Using a DVOM, check resistance of brake switch sense circuit between PCM connector C2 terminal No. 62 (White/Red wire) and brake switch connector (White/Red wire). If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open brake switch sense circuit. Perform If no other potential causes are remaining, PCM is assumed to be defective. Replace PCM. PCM is located to left of Power Distribution Center (PDC) in engine compartment. Perform TEST VER-4A: SPEED CONTROL VERIFICATION  .
  7. If no other potential causes are remaining, PCM is assumed to be defective. Replace PCM. PCM is located to left of Power Distribution Center (PDC) in engine compartment. Perform TEST VER-4A: SPEED CONTROL VERIFICATION  .
