Idle Speed Control Motor
- Disconnect Idle Speed Control (ISC) motor connector. Check motor coil continuity between motor terminals. Resistance should be 5-70 ohms at 68°F (20°C). If resistance is not as specified, an open or short exists in motor coil. Replace ISC servo assembly.
- Connect 6 volts DC (four 1.5-volt DC batteries) between ISC motor terminals to operate ISC motor. DO NOT apply more than 6 volts. If motor does not operate, replace ISC motor assembly.
