- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector terminals. Repair as required. Perform VERIFICATION PROCEDURE VER-2. If PCM connector is okay, go to next step.
- Place DRB-II in ohmmeter mode. Using DRB-II, check resistance of PCM connector terminal No. 47, speed sensor signal circuit (White/Orange wire). If resistance is less than 5 ohms, repair short to ground in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2. If resistance is more than 5 ohms, go to next step.
- Using an external ohmmeter, check resistance of speed sensor signal circuit (White/Orange wire) between vehicle speed sensor connector and PCM connector terminal No. 47.
- If resistance is more than 5 ohms, repair open in White/Orange wire. Perform VERIFICATION PROCEDURE VER-2. If it is less than 5 ohms, replace PCM. Perform VERIFICATION PROCEDURE VER-2.
