DIAGNOSIS
Ask the customer the following questions:
^
Was the fuel tank filled with the engine running or with the ignition switch in the II/ON position?
^
Was the fuel filler door opened again after the fuel tank was filled (such as when washing the car)?
^
Was the fuel tank only partially filled?
A "yes" answer to any of these questions would explain why the DISTANCE TO EMPTY display reads N/A. Explain to the customer that the
Information Center must get an ignition switch "OFF" signal, a fuel filler door "OPEN" signal, and a fuel tank "FULL" signal in order to reset and
display the DISTANCE TO EMPTY properly. To reset the DISTANCE TO EMPTY in this situation, simply refill the fuel tank completely with the
ignition switch off.
If the answer to all of the questions above was "no," test the fuel filler door switch as follows:
With the 16P connector still plugged into the Information Center Control Unit, connect a voltmeter positive lead to the BRN terminal and the negative
lead to body ground. Turn the ignition switch on.
^
With the fuel filler door opener lever in its normal position (down), the voltmeter should read 5V. If not. check the fuel filler door switch and the
BRN wire for a short to ground.
^
With the fuel filler door opener lever pulled up. the voltmeter should read less than 1 V. If not. check for an open in the BRN wire or a poor
ground at G15. If the wire and ground are OK, replace the fuel filler door switch.
