  2. Turn ignition on. Using a voltmeter, measure voltage between ground and test switch terminal (Blue/Red wire) of test connector. If reading is 10-14 volts, check for an intermittent problem. See TESTS W/O CODES article. If reading is not as specified, go to next step.
  3. Turn ignition off. Disconnect PCM harness connectors. Turn ignition on. On models with 3-speed automatic or manual transmission, measure resistance between ground and PCM harness connector "C", terminal No. 6 (Blue/Red wire). On models with 4-speed automatic transmission, measure resistance between ground and PCM harness connector "D", terminal No. 18 (Blue/Red wire). If continuity exists, repair Blue/Red wire for short to ground. If no continuity exists, replace PCM. Retest system.
