Test SC-2A - Checking Speed Control On/Off Switch

WARNING: This page is about a different car, the 1996 Plymouth Breeze, 1996 Dodge Stratus, 1996 Chrysler Cirrus, 1995 Dodge Stratus, and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST SC-1A - CHECKING SPEED CONTROL OPERATION  before proceeding.
  1. Turn ignition on. Using scan tool, read speed control switch voltage. If voltage is 4 volts or less, go to next step. If voltage is more than 4 volts, go to step  3.
  2. Disconnect 2-pin SET/RESUME switch connector (located behind speed control SET/RESUME switch). Using scan tool in voltmeter mode, check voltage of 2-pin SET/RESUME switch connector signal circuit Red/Light Green wire. If voltage is 4 volts or less, go to next step. If voltage is more than 4 volts, replace speed control SET/RESUME switch. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  3. Disconnect 2-pin ON/OFF switch connector (located behind speed control ON/OFF switch). Using scan tool in voltmeter mode, check voltage of 2-pin ON/OFF switch connector signal circuit Red/Light Green wire. If voltage is 4 volts or less, go to next step. If voltage is more than 4 volts, replace speed control ON/OFF switch. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  4. Disconnect Powertrain Control Module (PCM) connector. Using scan tool in ohmmeter mode, check resistance of speed control switch signal circuit at PCM connector terminal No. 41 Pink/Light Green wire. If resistance is 5.1 k/ohms or more, replace PCM. Perform TEST SC-VER - SPEED CONTROL VERIFICATION . If resistance is less than 5.1 k/ohms, repair short to ground on speed control switch signal circuit. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  5. Disconnect 2-pin speed control ON/OFF switch connector (located behind speed control ON/OFF switch). Connect a jumper wire between 2-pin speed control ON/OFF switch connector terminals. Turn ignition on. Using scan tool, read speed control switch voltage. If voltage is one volt or more, go to next step. If voltage is less than one volt, replace speed control ON/OFF switch. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  6. Remove jumper wire from 2-pin speed control ON/OFF switch connector. Using scan tool in voltmeter mode, check voltage of speed control switch signal circuit at 2-pin speed control ON/OFF switch connector. If voltage is 4 volts or less, go to next step. If voltage is more than 4 volts, repair open ground circuit on 2-pin ON/OFF switch connector. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  7. Disconnect 4-pin clockspring connector. The 4-pin clockspring connector is located behind steering wheel. Turn ignition on. Using scan tool in voltmeter mode, check voltage of speed control switch signal circuit Red/Light Green wire at 4-pin clockspring connector. If voltage is 4 volts or less, go to next step. If voltage is more than 4 volts, replace clockspring. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
  8. Disconnect PCM connector. Using an external ohmmeter, check resistance of speed control switch signal circuit Red/Light Green wire between 4-pin clockspring connector and PCM connector terminal No. 41. If resistance is 5 ohms or more, repair open Red/Light Green wire. Perform TEST SC-VER - SPEED CONTROL VERIFICATION . If resistance is less than 5 ohms, replace PCM. Perform TEST SC-VER - SPEED CONTROL VERIFICATION .
