Note on display field 1: The internal calculation value in the ECM for the duty cycle is displayed without power and voltage correction.

Note on display field 2: The actual power draw by the Idle Air Control (IAC) valve -N71- is displayed.

Note on display field 3:
- Positive values indicate increase in the duty cycle, in order to reach the specified current.
- Negative values indicate a decrease in the actual duty cycle to reach the specified current.
- If +60% is displayed for a longer time, this indicates contact resistance and/or an IAC valve that is too hot.
- If -4O% is displayed for a longer time, this indicates a winding short in the idle air control valve.
