Description of On-Board Diagnostics
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.
