Test 6A - Bus Short To Ground

NOTE: Perform TEST VER-1A  after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Turn ignition off. Disconnect Powertrain Control Module (PCM). PCM is located at right corner of firewall. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace PCM. If scan tool displays BUS SHORT TO GROUND, go to next step.
  2. Turn ignition off. Disconnect instrument cluster. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace instrument cluster circuit board. If scan tool displays BUS SHORT TO GROUND, go to next step.
  3. Turn ignition off and wait 5 minutes. Disconnect Air Bag System Control Module (ABSCM). ABSCM is located under center console. Turn ignition on. If scan tool does not display BUS SHORT TO GROUND, replace ABSCM. If scan tool displays BUS SHORT TO GROUND, go to next step.
  4. Disconnect scan tool from DLC. Using external ohmmeter, measure resistance between ground and terminal No. 3 (Violet/Brown wire) on DLC connector. If resistance is less than 700 ohms, repair Violet/Brown wire for short to ground. If resistance is 700 ohms or greater, go to next step.
  5. Measure resistance between ground and terminal No. 11 (White/Black wire) on DLC connector. If resistance is less than 700 ohms, repair White/Black wire for short to ground. If resistance is 700 ohms or greater, replace scan tool cable or scan tool as necessary.
