Component Tests and General Diagnostics





DIAGNOSIS AND TESTING - RKE TRANSMITTER

Special Tools:









Figure 1 - Radio Frequency Detector 9001
Use a Radio Frequency Detector such as special tool (9001) to confirm that the Remote Keyless Entry (RKE) transmitter is functioning. Typical testing distance is 30.5 centimeters (12 inches).

1. Position the transmitter the appropriate distance from the special tool.
2. Depress any transmitter button, then test each button individually. The special tool will issue an audible beep tone if a satisfactory radio signal strength that lights five or more LED units is detected.
3. Repeat Step 2 three times. If the transmitter fails any of the signal strength tests, use a diagnostic scan tool and the appropriate diagnostic information to complete further diagnosis.
