Neutral Drive Switch (NDS) A/C Input

With ignition switch in OFF position, set DVOM to 200-ohm scale. Locate NDS switch (on transmission) and clutch switch (on clutch pedal linkage). Disconnect harness at both switches. Measure resistance across NDS terminals with transmission in Neutral and across clutch switch terminals with clutch pedal fully depressed. If each resistance is greater than 5 ohms, switches are open. Replace switches. Faults in switches or switch circuits should set a service code. See Quick Test procedure in TESTS W/CODES EEC-IV article in the ENGINE PERFORMANCE Section. If no service code has been set, see CIRCUIT TEST TA in TESTS W/CODES EEC-IV article for additional switch testing and specifications.
