Diagnostic Trouble Code Tests and Associated Procedures

Fig. 2 Code Diagnosis Chart:

Refer to Fig. 2, for code diagnosis. These codes are generated by the controller module. If a system fault is detected, the controller module will ``flash out'' the corresponding fault code on the electronic four-wheel drive lamp on instrument panel. Also, notice all codes that can be generated pertain only to the speed sensors, the clutch coil and clutch with the exception of the first flash code.
The electronic four-wheel drive system also includes the brake switch input, neutral drive switch input, one power and two ground lines, along with the E4WD lamp. If ignition is turned off and code is lost, the ignition will have to be turned on again to regenerate Codes 1 through 8, if condition or conditions still exist. To regenerate Codes 9 through 16, the vehicle must be driven again.
