Input Test Mode

The Input Test mode individually tests the Central Timer Module (CTM) inputs. It is entered from the Diagnostic Trouble Code (DTC) Output mode when the operator puts the key in the ignition assembly. Inputs may be tested in any order. As an input is toggled on or off, the door ajar indicator (if the ignition switch is in the RUN position) and tone outputs will be activated for one second for confirmation. At any time, if the key is removed from the ignition switch, the DTC Output mode will be re-entered.







Note that all CTM functions remain disabled while in the diagnostic test mode. The chart shows all the possible inputs that can be tested for the CTM Controlled Interior Lighting System.

NOTE: Several of the inputs will not operate unless the ignition is in the RUN position.
