Test TC-152A: Brake Switch Sense Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- Turn ignition off. Disconnect brake switch connector. Turn ignition on. Using a voltmeter, check voltage of brake switch sense circuit at brake switch connector. See BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION table. If voltage is more than 9 volts, go to next step. If voltage is 9 volts or less, go to step 4) .
- Observe brake switch status on scan tool. Connect a jumper wire from brake switch sense circuit to ground. If scan tool display changed from PRESSED to RELEASED, replace brake switch. Perform TEST VER-2A. If scan tool display did not change, go to next step.
- Using a ohmmeter, check resistance of ground circuit between brake switch connector and ground. See BRAKE SWITCH CONNECTOR WIRE IDENTIFICATION table. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A. If resistance is 5 ohms or more, repair open ground circuit. Perform TEST VER-2A .
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector for pushed out terminals or damage. Repair PCM connector as necessary. Perform TEST VER-2A . If PCM connector is okay, go to next step.
- Using a ohmmeter, check resistance of brake switch sense circuit between PCM connector terminals No. 50 and 62. See PCM CONNECTOR WIRE IDENTIFICATION table. 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 TEST VER-2A .
- Using a ohmmeter, check resistance of brake switch sense circuit between PCM connector terminal No. 62 and ground. See PCM CONNECTOR WIRE IDENTIFICATION table. If resistance is less than 5 ohms, repair short to ground on brake switch sense circuit. Perform TEST VER-2A . If resistance is 5 ohms or more, replace PCM. Perform TEST VER-2A .
