After Code .7.0 is displayed following the ``Switch Tests'', the ``Engine Data Display Procedure'' may be performed.
1. Depress and release ``reset'' button on Fuel Data panel. Engine data series begins as display switches from Code .7.0 to Code .9.0. If display does not advance to Code .9.0 refer to Code .7.9 of switch tests.
2. To advance display, depress ``instant/average'' button on Fuel Data panel. To return to a previously displayed parameter, depress ``reset'' button on Fuel Data panel. To leave engine data and return to Code .7.0, simultaneously depress OFF and HI buttons on ECC control panel. After last parameter is displayed, system advances to Code .9.5 and waits for next command.
3. When troubleshooting a malfunction, engine data display can be used to compare vehicle with problems to a vehicle that is functioning properly. When engine data display is initiated, ECC will display 01 for one second to indicate first parameter check, then a number will be displayed for nine seconds to indicate first parameter value. The ECC will continue to repeat this sequence of events until next parameter is selected, Fig. 10.
