Troubleshooting Hints - Steering Wheel Controls

1. Check Fuse 38. If open, check CKT 43 for a short to ground.
2. Check that grounds G201 and G203 are clean and tight.
3. If switches on one side of the Steering wheel operate but the other side is inoperative, replace Steering Wheel Control Switches.
^ Check for a broken (or partially broken) wire inside of 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.
