Component Tests and General Diagnostics

(Perform before beginning System Diagnosis)

1. Check Fuses 7 and 8 in I/P Fuse Block. If open, refer to Chart # 3. Chart 3 Power Door Lock Fuse Blows Out After Replacement

2. Check for a poor connection at G200.

3. If the Transmitter fails to operate from a normal distance, up to 7 to 10 meters (22 to 33 ft.), check for two conditions: weak batteries in Transmitter (expected life approximately 2 years depending on use); or close proximity to a Radio Transmitter, such as a Radio Station Tower, air port Transmitter, and some mobile or CB Radios.

4. Try a second Transmitter if available. If the second Transmitter works, remove the Battery and install the Battery in the original Transmitter. Try the original Transmitter again. If the original Transmitter still does not work, it is defective.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check. Use Test Light J 34142 whenever possible. Test lights require more current than a high impedance DVM and are more useful for detecting abnormally high resistive circuits. Some test lights have high impedances and will not be as useful in detecting resistive circuits.

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.

Perform the System Check and refer to the Symptom Table for the appropriate diagnostic procedures. Initial Inspection and Diagnostic Overview A Symptom Table
