Test 5B - Bus Short To 5 Volts

NOTE: For connector terminal identification see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  . Perform, after each repair, VERIFICATION TEST VER-1A - VERIFICATION PROCEDURE  .
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Turn ignition off. Using external ohmmeter, measure resistance between terminal C30 (Violet/Brown wire) on Powertrain Control Module (PCM) Gray connector and terminal A17 (Violet/Black wire) on PCM Black connector. PCM is located at right inner fender. If resistance is less than 800 ohms, repair short between Violet/Brown wire and Violet/Black wire. If resistance is 800 ohms or greater, go to next step.
  2. Measure resistance between terminal C28 (White/Black wire) on PCM Gray connector and terminal A17 (Violet/Black wire) on PCM Black connector. If resistance is less than 800 ohms, repair short between Violet/Black and White/Black wires of both connectors. See wiring diagram for clarification. If resistance is 800 ohms or greater, replace PCM.
