    have 97 1500 4x4 runs fine 110k but service engine light comes on sometimes used 2 scan tools to try get codes but one say voltage to high and will not communicate the other just will not comm. found pin 2 at dianostic port to have 10.4 volts switch on only also found fuse type diod in engine comp. fuse box that is lable diode 2 but thew only one used when removed pin 2 has 2.4 volts got another diod from 5.7 truck compared readings with old diodew both check good for no reverse voltage but the voltage thru side old one has 1.6m ohms and other one has 1.95m ohms 350,000m more when put the second one in switch on pin 2 had 2.4 volts for about 15 min then went to 10.4 volts recheck diode still has same readings as before was told that pin 2 should be 2 volts with diode removed has 2.4 but tools still will not communicate with ecm

    Are you sure your using the right scan tool? OnBoardDiagnostics.com - OBD-II Network Standards
    All it says voltage to high? maybe code is voltage too high? Take it to auto parts for a free scan..see what their says?? click on blue links www.troubleshootmyvehicle.com/gm/4.3L-5.0L-5.7L
    /pcm-connector-pin-outs-1996-1997-page-1
    Pin 10 is a floating ground for pin 2 check voltage on pin 2 with key on.
    This will be interesting why pin 2 has high voltage?
    Use a digital voltmeter to check the DLC connector:
    1. Check ground continuity. Connect the positive
    (+) meter lead to DLC pin 4. Connect the
    negative (-) meter lead to the negative battery terminal. Use jumper wires as needed. Do
    741
    not connect to a body or chassis ground; go di
    rectly to the battery terminal if at all
    possible.
    With the ignition on, voltage drop across the ground terminal should be 0.1 V or less.
    Repeat for DLC pin 5. An open circuit or high ground resistance prevents the ECM from
    entering diagnostic mode.
    2. Check voltage on pin 2 of the DLC. The PCM transmits data on this pin. Connect the
    positive voltmeter lead to the class 2 serial da
    ta pin and the negative lead to either pin 4,
    pin 5, or a known good ground. With the ignition on, voltage on the class 2 serial data pin
    should be either 5 V or fluctuating between
    3.5 and 5.0 V. If the circuit is open, the ECM
    cannot transmit data to the scan tool.
