0000001801 V-FICD ADJUSTMENT
Adjustment of the V-FICD (perform with W-FICD released)
1. Adjust to obtain L1.
2. Set at L2 when negative pressure P1 is applied to the actuator.
Adjust the stroke using the actuator stroke adjusting screw (F).

0000001901 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Adjustment of the timer stroke
Adjust screw (A) so that the timer stroke is the value determined from the graph.
2. Adjustment of the position of the intermediate lever.
Insert a shim L3 between the control lever (I) and the idle screw (G).
Align the intermediate lever (F) with the aligning mark (J) and then fix the intermediate lever adjusting screw (E) so that (E) contacts the shim between (E) and (I).
3. Adjustment of the FICD
Insert a shim L4 between the control lever (I) and the idle set screw (G).
Use adjusting screw (B) to fix the CSD lever (C) in the position where it operates the intermediate lever (F) via the rod (D). [(U), (V)]
(O) Timer stroke adjustment (mm)
(P): lever angle (deg)
(Q): lever angle (deg)
The (Q) indicates the clearance between the control lever and the idle set screw.

Information:
The diagnostic lamp, on the truck dashboard, can be used to communicate status or operation problems of the electronic control system.Trucks With Cruise
The dash mounted cruise switches are used to interrogate the ECM for system status. With the cruise switch in the "off" position, hold the set/resume switch in the resume position until "check engine" light begins to flash. The sequence of flashes represents the system diagnostic message. The first sequence of flashes adds up to the first digit of the fault code. After a one second pause, a second sequence of flashes will occur which represents the second digit of the fault code. Any additional fault codes will follow, after a pause, and will be displayed in the same manner.Trucks Without Cruise
If cruise control switches are not installed or if their configuration (such as a GM type switch) does not permit their usage for checking diagnostic codes, then a push button momentary ON switch should be installed between Pin 3 of the vehicle connector P7 and engine ground.Faults With Throttle Response
The vehicle should be driven to a dealer for service ONLY if the engine oil pressure gauge indicates normal engine oil pressure and engine fuel pressure is within the normal range.Faults Without Throttle Response
If the check engine light is on and the engine does not respond to changes in throttle position, the vehicle should be driven to a dealer ONLY if the oil pressure gauge indicates normal engine oil pressure and engine fuel pressure is within the normal range.If equipped, turn on the cruise on/off switch and operate the vehicle using the set/resume cruise control switch to raise and lower the engine rpm.The cruise control mode is operational from 0 km/h (mph) up to the vehicle speed limit (VSL) when the 3406B (PEEC III) control unit does not respond to changes in throttle position. Maximum engine rpm will be the programmed engine rpm at the vehicle speed limit (VSL). Cruise control must be reselected after each gear change.
