Neutral Drive Switch (NDS) A/C Input Test
Key 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 the clutch pedal down. If each resistance value is more than 5 ohms, switches are open. Replace switches.
