Initial Inspection and Diagnostic Overview

Note: Perform before beginning System Diagnosis

1. If Gages Fuse #9 is open, refer to Chart #3 in this section. Chart 3 Fuse #9 Blows When IGN on, or Depressing Brake Pedal
2. Check Brake Switch Assembly for proper adjustment.
3. Check Fusible Link between S257 and S245. See Wiring Schematic and Component Location.
4. If Transmission Shifter does not shift out of "PARK," check linkage and cable for binding. Check for poor connection at C210 terminal "A."
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check. Use Test Light J 34142 whenever possible.

Note: Test lights require more current than a high impedance DVM and are more useful for detecting abnormally high resistive circuits. Some test lights have high impedances and will not be as useful in detecting resistive circuits.

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
