^ Circuits 821 or 822 are shorted to ground at the P style hold-down clamp on the side of the transmission (figure 9). These circuits have also been known to short to ground on the underdash bracket near the DRAC. The DRAC is located on the driver's side under the dash (figure 10).

^ Ground G-200 loose, not installed or corroded. G-200 is mounted under the driver's side of the instrument cluster next to the fuse block. It may be necessary to add an extra ground for this location. Note: A poor ground for this circuit may also cause intermittent operation of other systems which rely on this ground for proper operation, such as the dome light and brake system circuits.

^ Grounds G-124 and G-125 are the braided ground cables between the vehicle body and the engine. If one of these straps are loose, corroded or not installed, many symptoms may result including a code 72. It is imperative that these grounds be in place and in good condition.




^ Circuit 437 shorted to ground by a sheet metal screw in the vicinity of the PCM (figure 11).




^ Connector C-104 may be coated with undercoating, causing poor terminal contact. C-104 is a two-wire connector mounted on the driver's side of the cowl area, engine compartment side, near the bulkhead connector (Figure 12).

^ Connector C-100 is damaged or loose. C-100 is mounted on the driver's side of the cowl area, engine compartment side, and serves as the bulkhead connector. C-100 has been known to corrode from battery acid or fumes if the connector is not properly sealed.
