Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
