0000001801 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Adjustment of the timer stroke
Adjust using screw (A) so that the timer stroke is the value determined using the graph (W). [(K), (M)]
2. Adjustment of the position of the intermediate lever.
With a shim L5 inserted between the control lever (I) and the FICD set screw (E), insert a shim (L3) between (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). [(U), (V)]
3. Adjustment of the FICD
Insert the 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)]
However, set with a shim L5 inserted. [(U), (V), (W)]
(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.

ACTIVE Diagnostic Codes
Diagnostic codes are used by the PEEC III system to warn the vehicle operator of a problem and indicate to the service technician the nature of the problem. Some codes are used only to record an event, and do not indicate problems.An ACTIVE Diagnostic code represents a problem that should be investigated and corrected AS SOON AS POSSIBLE. Repairing the cause of an ACTIVE code will cause the code to be cleared from the ACTIVE Diagnostic Code screen.When an ACTIVE code is generated, the PEEC III lamp will turn ON and remain ON, blinking every five seconds. If the condition generating the fault occurs only for a brief moment, the lamp will go OFF after five seconds and the fault will be LOGGED. After a problem has been investigated and corrected, the related diagnostic code should be cleared from memory.ACTIVE codes may be viewed using either of the electronic service tools (ECAP or DDT), and may also be viewed using the diagnostic lamp and cruise control switches. The diagnostic lamp should not be confused with the warning lamp which is used with PEEC III engine protection.Using The ECAP Or DDT To Display ACTIVE Codes
A. With key OFF, install an ECAP or DDT into the PEEC III system.B. Turn key ON (engine does not need to be started to view codes).C. Refer to the Operating Manual and Special Instructions for the service tool (listed under PEEC III Service Tools) to read the code(s). On the ECAP, the display menu will direct you to the proper screen to display diagnostic messages similar to the example below.Using The Cruise Control Switches To Display ACTIVE Codes:
A. Turn key ON (engine does not need to be started to view codes).B. The PEEC III Diagnostic Lamp will turn ON for five seconds, blink OFF for 1/10 second, turn ON again for five seconds, then OFF for five seconds. At the end of that time, the lamp will begin to flash the first number of the two-digit code (count the flashes). After two seconds OFF, then it will flash the second digit. If two or more codes are present, they will follow the first after a few seconds and be displayed in the same manner.C. Active Diagnostic codes may be displayed at any time by using cruise control switches. With key ON or engine running, turn the cruise control ON/OFF switch to OFF, and move the SET/RESUME switch to RESUME position. Once the codes begin to flash the switch may be released. The PEEC III Diagnostic Lamp will flash out all the codes that are currently active, or intermittent codes that have occurred since the key was turned on. LOGGED Diagnostic Codes
When an ECM generates a diagnostic code, it usually logs the code in permanent memory within the ECM. The time the code occurred (in hours on the internal diagnostic clock) is logged along with the code. The logged codes can then be later retrieved or erased using an ECAP or DDT service
