Status Indicator RAPs
Generic Clutch RAP
Initial Actions
NOTE: This procedure can be used to check any clutch. Due to the generic format of this RAP
there will be no specific ADJ, PL or Diagnostic codes identified. The PWB names, voltages,
connectors, and pin numbers are fictitious. Refer to the appropriate BSD for the actual names
and numbers
Procedure
(Figure 1): Enter DIAGNOSTICS (General Procedures). Enter code [xxxx] to test the Clutch
(Refer to appropriate BSD for the specific code). Actuate the Clutch. The Clutch energizes.
YN
Deactuate the clutch. There is +24 VDC at J209-12 (use the actual connector/pin
number on the BSD) on the PWB (AX).
YN
Check the wire for an open circuit. If the wires are good, replace the Clutch (PL X.X).
Check the adjustment of the Clutch (ADJ X.X).
If the adjustment is good, replace the Clutch (PL X.X).
The Clutch and its circuit appear to be operating normally. Check the adjustment or alignment
of the Clutch.

Generic Sensor RAP
Initial Actions
NOTE: This procedure can be used to check any sensor. Due to the generic format of this RAP
there will be no specific ADJ, PL or Diagnostic codes identified. The PWB names, voltages,
connectors, and pin numbers are fictitious. Refer to the appropriate BSD for the actual names
and numbers.
• Ensure that the Sensor is not blocked.
• Clean the Sensor surfaces before using this procedure.
Procedure
(Figure 1): Enter DIAGNOSTICS (General Procedures). Enter code [xxxx] to test the Sensor
(Refer to appropriate BSD for the specific code). Block the Sensor. The Display toggles
between [1] and [0].
YN
There is +5 +/-0.3 VDC at J60X/P60X pin X of the Main PWB.
YN
The + 5 VDC LED on the Main PWB is on
YN
Refer to the 1.2 DC Power RAP
Replace the Main PWB.
Check the wiring to the sensor for an open circuit.
If the wiring is good, replace the Sensor.
The Sensor and its circuit appear to be operating normally, check the adjustment or alignment
of the Sensor.
