Test TC-86A - Speed Control Switch Always High

WARNING: This page is about a different variant/trim than selected.
  1. Using scan tool, read speed control inputs. While observing scan tool display, push speed control ON/OFF switch several times and leave on. If scan tool displays speed control switch on and off, go to TEST TC-86B - SPEED CONTROL SWITCH ALWAYS HIGH . If scan tool does not display speed control switch on and off, go to next step.
  2. Disconnect 2-pin speed control ON/OFF switch connector (located behind speed control ON/OFF switch). Using scan tool in voltmeter mode, check voltage on 2-pin speed control switch connector signal circuit Red/Light Green. If voltage is 4.8 volts or less, go to next step. If voltage is more than 4.8 volts, repair short to voltage on signal circuit. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  3. Turn ignition off. Using scan tool in ohmmeter mode, check resistance of 2-pin speed control switch connector ground circuit Black/Light Green wire. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open ground circuit. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  4. Disconnect Powertrain Control Module (PCM) connector. Using scan tool in ohmmeter mode, check resistance of signal circuit Red/Light Green wire between 2-pin speed control switch connector and PCM connector terminal No. 41. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, go to step  6.
  5. Using an external ohmmeter, check resistance across speed control ON/OFF switch terminals. If resistance is less than 25 k/ohms, replace PCM. Perform TEST SC-VER - SPEED CONTROL VERIFICATION . If resistance is 25 k/ohms or less, replace speed control ON/OFF switch. Perform TEST VSS-VER - ROAD TEST VERIFICATION .
  6. Disconnect 4-pin clockspring connector. Using an external ohmmeter, check resistance of speed control ON/OFF switch signal circuit Red/Light Green wire between 4-pin clockspring connector and PCM connector terminal No. 41. If resistance is less than 5 ohms, repair open signal circuit at clockspring connector. Perform TEST VSS-VER - ROAD TEST VERIFICATION . If resistance is 5 ohms or more, repair open signal circuit between 4-pin clockspring connector and PCM connector terminal No. 41. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
