ERROR CODE TROUBLESHOOTING
1.
The RTCH has six (6) Electronic Control Units (ECUs) that are at the heart of the on-board diagnostic system. The loca-
tion of each computer (ECU) is identified in Table 1 below and in Figures 1 and 2 at the end of this work package.
2.
The driver’s Electronic Control System (ECS) screen displays error codes based on data collected from each of the other
computers. Refer to Explanation of Error Code Display, in this work package, for more information on how to read this
display.

WP 0205 00, Error Codes, provides a complete listing of the error codes visible to both the operator and maintainers of
the RTCH.

While performing troubleshooting, it may be necessary to access the system Diagnostic, Calibration or Initialization
Menus. As a maintainer of the RTCH, you are authorized to access these menus as part of the troubleshooting process.
These menus, which are not normally available to the operator, provide additional information that will help you diag-
nose a problem.
