DIAGNOSTICS
The Central Timer Module (CTM) is fully addressable with 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 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.
