July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Test 11B - Bus Short To Battery

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. 44 (Orange wire) and No. 59 (Violet/Brown wire). PCM is located on left inner fenderwell, near battery. If resistance is less than 5 ohms, repair short between Orange wire and Violet/Brown wire. If resistance is 5 ohms or more, go to next step.
  2. Measure resistance between PCM connector terminals No. 44 (Orange wire) and No. 60 (White/Black wire). If resistance is less than 5 ohms, repair short between Orange wire and White/Black wire. If resistance is 5 ohms or more, replace PCM.
