Test 4B - Bus Short To Battery

NOTE: Perform 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 ground and terminal A31 (Black/Tan wire) on Powertrain Control Module (PCM) Black connector. PCM is located at right corner of firewall. If resistance is less than 10 ohms, go to next step. If resistance is 10 ohms or greater, repair open Black/Tan wire.
  2. Measure resistance between ground and A32 (Black/Tan wire) on PCM Black connector. If resistance is less than 5 ohms, replace PCM. If resistance is 5 ohms or greater, repair open Black/Tan wire.
