Location of Screwdriver While Holding BellcrankK. Rotate the timing position sensor bellcrank clock wise by inserting the No. 2 Phillips screwdriver between the arm of the bellcrank in contact with the timing position sensor until the screwdriver can be inserted into the hole in the cover to hold the bellcrank in position.
Hold Timing Position Sensor Bellcrank In PositionL. Install the gasket and timing advance housing (4).M. Remove the screwdriver to allow the bellcrank to contact the power piston.9. Check the timing sensor position calibration as described in P-531: Timing Position Sensor/Calibration.10. Install the timing solenoid (BTM). Make sure the arm of the timing solenoid is in the center groove of the control spool collar.11. Install the timing advance position sensor cover (3).P-540: Idle Shutdown Timer
System Operation
The idle shutdown timer is a feature which helps improve fuel consumption by limiting idling time. The timer may be programmed to shut down the idling engine after a period of time. This "shutdown time" is a customer specified parameter, and may be programmed for any period from 3 to 60 minutes. Programming the time to zero disables the idle shutdown timer.The timer is activated when the parking brake is set, vehicle speed is zero, and the engine is not under load. Ninety seconds before the programmed time is reached, the diagnostic lamp will begin to flash rapidly. If the driver moves the clutch pedal or brake pedal during this 90 second period, the timer will be overridden and is reset. A diagnostic code 71-00 will be set when the driver overrides the timer using the clutch or brake.If the timer is activated and allowed to shutdown the engine, then a code 71-01 will be set. Code 71-01 merely records the event and does not indicate a fault in PEEC III. If any of the codes for vehicle speed are Active, the idle shutdown timer will not operate.Diagnostic Codes

P-541: Multi-Torque
System Operation
Multi-Torque is an optional feature available with certain PEEC III engines. The feature is available only in certain personality modules.The 310 Multi-Torque provides an otherwise standard 310 hp PEEC III engine with two different torque curves. In all gears except top gear, the engine performs as a standard 310 hp PEEC III. In top gear, however, the engine is provided with the torque of a standard 310 hp at 1800 rpm, but with the peak torque of 350 hp at 1150 rpm (see the following illustrations).PEEC III determines whether the vehicle is in top gear by sensing the ratio of engine speed to vehicle speed. If the ratio of engine speed/vehicle speed is less than 26.6, the engine will perform like a standard 310 hp PEEC III.The 350 Multi-Torque works just like the 310Multi-Torque, except for two key differences. First, the multi-torque curve provides the engine with the standard 350 hp torque at 1800 rpm, and with the peak torque of a 400 hp at 1200 rpm (see the following illustration). Second, the multi-torque is in effect in the top two gears,
