(A17) Harness code 2 (A18) Harness code 1 (A19) Harness code 0 (A36) Harness code 4 (A37) Harness code 3This check is necessary if the wrong machine code is shown during the self test or a harness code fault CID 0650 FMI F02 is detected. The possible cause for the harness code problem is listed below.
The machine harness is faulty.
The wrong machine harness plug is being installed.
The ARC is faulty.The harness code and the machine code are similar terms that are used to describe the particular machine to the ARC. The harness code is the status of the five harness code inputs A17, A18, A19, A36, and A37. The machine code is a number that is used by the ARC for a particular harness code for a particular machine. The machine code is shown during the self test. Each sales model has a specific harness code and a specific machine code.This procedure uses the harness code status mode to check the harness code circuits in the machine harness. Refer to the Testing and Adjusting, "Harness Code Status Mode" for more information.
Check the harness code. Place the display in the harness code status mode (mode 4).
Observe the segments of the display. Compare the sales model and the display segment status to the data on Table 1.
The sales model and the machine code agree with Table 1. The harness code circuits in the machine harness are correct. Go to Step 3.
The sales model and the display segment do not agree with Table 1. The wrong harness code circuits in the machine harness are open or grounded. Use the electrical schematic and Table 1 in order to help troubleshoot the problem.
Check the machine code. Perform a self test by turning the key switch from OFF to On. Observe the display and note the machine code that is displayed during this test. Compare the display to Table 1.
The sales model and the machine code agree with the table. The harness code circuits and the ARC are correct. No defects are found. Check the machine harness for dirty connectors, bent contacts, and frayed wires.
The sales model and the machine code do not agree with Table 1. There is a malfunction. The problem is unlikely that the ARC is faulty. Repeat the preceding procedure again. If the results are not changed, replace the ARC. Refer to Testing and Adjusting, "ARC - Replace" for any questions.
