Test 12B - Bus Short To 5 Volts

NOTE: For connector terminal identification see CONNECTOR IDENTIFICATION  . For wiring diagrams, see WIRING DIAGRAMS  . Perform VERIFICATION TEST VER-1A  after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Turn ignition off. Using external ohmmeter, measure resistance between Powertrain Control Module (PCM) connector terminals No. 59 (Violet/Brown wire) and No. 61 (Violet/White wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Violet/White wire. If resistance is 5 ohms or more, go to next step.
  2. Measure resistance between PCM connector terminals No. 60 (White/Black wire) and No. 61 (Violet/White wire). If resistance is less than 5 ohms, repair short between White/Black wire and Violet/White wire. If resistance is 5 ohms or more, replace PCM.
