2. Set digital voltmeter to AC setting.
3. Disconnect white electrical connector from logic module and connect voltmeter between terminal Nos. 18 and 20.
4. If voltmeter reading cycles between 0 and 6 volts, check for open circuit in wiring between automatic idle speed motor and terminal Nos. 18 and 20 of logic module white electrical connector.
5. If voltmeter does not cycle, replace logic module.

CAUTION: Before replacing the logic module check the terminals in cavities 18 and 20 of the logic module white connector to make sure they are not crushed causing a poor connection.
