Troubleshooting Hints - Upfitter Provisions
1. CHECK condition of RADIO-I Fuse, AUX-A Fuse, and AUX-B Fuse. If any fuse is open, LOCATE and REPAIR cause of overload and the
REPLACE Fuse(s).
2. CHECK that Grounds G106 and G201 are clean and tight.
^
CHECK for a broken (or partially broken) wire inside the insulation which could cause system malfunction but prove GOOD in a
Continuity/Voltage check with a system disconnected. These Circuits may be intermittent or resistive when loaded, and if possible, should be
checked by monitoring for a voltage drop with the system operational (under load).
^
CHECK for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer Troubleshooting
Procedures). See: Diagrams/Diagnostic Aids
