Roadmaster V8-350 5.7L VIN P MFI (1995)
Cornering Lamp: Initial Inspection and Diagnostic Overview
Circuit Operation
Voltage is applied to the Headlamp Switch at all times. With the Headlamp Switch in "PARK" or "HEAD," voltage is applied to the Cornering Lamps
Switch, which is part of the Turn/Signal Switch Assembly. With the Turn Signal Switch in either the "TURN LEFT" or "TURN RIGHT" position,
voltage is supplied to the corresponding Front Sidemarker and Cornering Lamp. Both Lamps are permanently grounded, the LH Lamp to G102 and the
RH Lamp to G106.
Troubleshooting Hints
PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS:
1. Check I/P Fuse #31. If it is open, check CKT 240 for a short to ground.
2. Check I/P Fuse #41. If it is open, check CKT 308 for a short to ground and Refer to Exterior Lights for Diagnosis of Park Lamps. See: Testing
and Inspection
3. Make sure that G102 and G106 are clean and tight.
4. Check bulbs and sockets for damage or corrosion.
^
Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove G00D 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 to "General
Troubleshooting Procedures,"). See: Diagrams/Diagnostic Aids
