NTC-3A: Checking Speed Control Resume Switch

NOTE: Perform NTC-1A: CHECKING SPEED CONTROL OPERATION before proceeding.

Disconnect 2-pin RESUME/ACCEL switch connector (located behind speed control RESUME/ACCEL switch). Inspect connectors. Clean or repair as necessary. Connect a jumper wire between ground and 2-pin speed control RESUME/ACCEL switch connector (Red/Light Green wire). Turn ignition on. Using scan tool, read speed control switch voltage. If voltage is less than one volt, replace speed control RESUME/ACCEL switch. Perform TEST VER-4A: SPEED CONTROL VERIFICATION under VERIFICATION TESTS. If voltage is one volt or more, go to next step.
Remove jumper wire from 2-pin speed control RESUME/ACCEL switch connector. Using external ohmmeter, measure resistance between speed control RESUME/ACCEL switch (Black/Light Green wire) and ground. If resistance is less than 5 ohms, repair open speed control switch signal circuit between RESUME/ACCEL switch and clockspring. Perform TEST VER-4A: SPEED CONTROL VERIFICATION under VERIFICATION TESTS. See WIRING DIAGRAMS . If resistance is 5 ohms or more, repair open ground circuit (Black/Light Green wire). Perform TEST VER-4A: SPEED CONTROL VERIFICATION under VERIFICATION TESTS.
