Diagnostics

Diagnostics
The CTM is fully addressable with the DRB III and it is the recommended method for diagnosis. The CTM reports 6 Diagnostic Trouble Codes. All of the inputs to the CTM can be read with the DRB and the outputs can be actuated. If the inputs are OK and the outputs can be cycled with the DRB, the problem is usually the Central Timer Module.
