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

WARNING: This page is about a different car, the 1998 Plymouth Breeze, 1998 Dodge Stratus, and 1998 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST SC-1A  before proceeding.
  1. Turn ignition on. Using scan tool, read speed control switch voltage. If voltage is more than 4 volts, go to step 5). If voltage is 4 volts or less, go to next step.
  2. Disconnect 2-pin SET/RESUME switch connector (located behind speed control SET/RESUME switch). Using scan tool, read speed control switch voltage. If voltage is more than 4 volts, replace speed control SET/RESUME switch. Perform TEST SC-VER  . If voltage is 4 volts or less, go to next step.
  3. Disconnect 2-pin ON/OFF switch connector (located behind speed control ON/OFF switch). Using scan tool, read speed control switch voltage. If voltage is more than 4 volts, replace speed control ON/OFF switch. Perform 5TEST SC-VER  . If voltage is 4 volts or less, go to next step.
  4. Disconnect Powertrain Control Module (PCM) connector. Using external ohmmeter, measure resistance of speed control switch signal circuit between PCM connector terminal No. 41 (Pink/Light Green wire) and ground. If resistance is 5.1 k/ohms or more, replace PCM. Perform TEST SC-VER  . If resistance is less than 5.1 k/ohms, repair short to ground on speed control switch signal circuit. Perform TEST SC-VER  .
  5. Disconnect 2-pin speed control ON/OFF switch connector (located behind speed control ON/OFF switch). Using an external voltmeter, measure voltage of speed control switch signal circuit between 2-pin speed control ON/OFF switch connector (Red/Light Green wire) and ground. If voltage is more than 6 volts, repair speed control switch for short to voltage. Perform TEST SC-VER  . If voltage is 6 volts or less, go to next step.
  6. 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 less than one volt, replace speed control ON/OFF switch. Perform TEST SC-VER  . If voltage is one volt or more, go to next step.
  7. Remove jumper wire from 2-pin speed control ON/OFF switch connector. Turn ignition on. Using external voltmeter, measure voltage of speed control switch signal circuit between ON/OFF switch connector (Red/Light Green wire) and ground. If voltage is more than 4 volts, replace PCM. If voltage is 4 volts or less, repair open ground circuit on 2-pin ON/OFF switch connector.
