Isuzu IDSS 4H and 6H Engine ECM Parameters

PTO Operation

• Stationary Preset PTO: One of three power take off modes used to allow up to four preset engine speeds in Park or Neutral.
• Stationary Variable PTO: One of three power take off modes used to allow up to four preset engine speeds in Park or Neutral.
• Mobile Variable PTO: One of three power take off modes used to allow variable engine speeds in and out of gear and with or without vehicle speed.
• High Idle Switch Option PTO (6H Only): This option allows raising the engine speed designated to aid in faster engine warm-up using a dash mounted switch.
• High Idle Switch Engine Speed  (6H Only): The preset engine speed for the High Idle Switch Option PTO.
• PTO Standby Speed: The engine speed used to notify the driver just after the PTO main switch has been turned ON. This speed can also be used to operate the PTO.
• PTO Max Engine Speed: Maximum allows engine speed in PTO mode regardless of accelerator pedal input.
• PTO Max Vehicle Speed: Maximum vehicle speed allowed in PTO mode.
• PTO Engage Relay: This feature allows the control of a relay in PTO mode when certain adjustable parameters have been met.
• PTO Max Engage Speed: Maximum engine speed for PTO hydraulic pump protection before the PTO Engage Relay will be activated.
• PTO Feedback: An input used for PTO hydraulic pump protection which ensures the PTO Engage Relay has energized before allowing the engine speed to be raised.
• PTO Engine Shutdown with Circuit Input: A safety feature which allows immediate engine shutdown – when the engine shutdown circuit is grounded in PTO mode.
• PTO Shutdown with Circuit Input: A safety feature which allows the engine to return to base idle speed when a circuit is grounded in PTO mode.
• PTO Shutdown Vehicle Speed: A safety feature which turns OFF the PTO Engage Relay above the programmed vehicle speed.
• PTO Engine Shutdown Time Delay: The time between when the Engine Shutdown input is detected and the engine actually shuts down.
• Disable Cab Controls: An option to disable the cruise control switches and accelerator pedal inside the cab in PTO mode.
• Disable Cab Controls with Circuit Input: An option to disable the cruise control switches and accelerator pedal inside the cab in PTO mode with the disable cab control circuit switched to ground.
• Diesel Particulate Filter (DPF) Regeneration in PTO: Allows Diesel Particulate Filter regeneration in Mobile Variable PTO mode.
• PTO Brake/Clutch Override: Allows continuous PTO engine speed control with the brake pedal applied, which normally would cancel PTO.
• Park Brake PTO Enable: An option to need the park brake enabled in order to raise the engine speed beyond the PTO Standby Speed.
• PTO Set Speed: The first preset engine speed in Stationary Preset PTO mode when the cruise control set/resume switch is depressed.
• PTO Resume Speed: The second preset engine speed in Stationary Preset PTO mode when the cruise control resume/accel switch is depressed.
• PTO Increase RPM Rate: The engine speed increase amount in Stationary or Mobile Variable PTO mode when the cruise resume/accel switch is depressed.
• PTO Reduce RPM Rate: The engine speed decrease amount in Stationary or Mobile Variable PTO mode when the cruise set/coast switch is depressed.
• PTO Accel RPM Rate: The rate at which the engine speed changes when using the cruise control or remote switches.
• Remote PTO Set/Resume Switches: This option enables the use of the Remote PTO Set/Resume Switches for both Variable PTO modes.
• Remote PTO Set Speed AB Switches: This option enables the use of the Remote PTO Set AB Switches for the Stationary Preset Mode.
• Remote PTO Set Speed A: This is the preset engine speed in Stationary Preset PTO mode when the remote Set Speed A switch is depressed.
• Remote PTO Set Speed B: This is the preset engine speed in Stationary Preset PTO mode when the remote Set Speed B switch is depressed.
• Remote PTO Throttle: This option enables the use of a throttle type potentiometer to vary engine speed in all PTO modes.
• Remote PTO Throttle 0%: This indicates the lower voltage limit for the throttle potentiometer at the minimum or 0% throttle position.
• Remote PTO Throttle 100%: This indicates the upper voltage limit for the throttle potentiometer at the maximum or 100% throttle position.
• Remote PTO Throttle Max Engine Speed: Maximum allowed engine speed when using Remote PTO throttle regardless of accelerator pedal input.

• Relaxed Cruise Control: Allows the cruise control system to deviate up to 5 mph while in cruise control to reduce transmission gear hunting.

Exhaust Brake

• Exhaust Brake Mode: This option allows three modes during Exhaust Brake activation: Manual, Coast, and Latch.
• Exhaust Brake Latch Mode Engine Speed: The minimum engine speed allowed for exhaust brake activation in the exhaust brake latch mode.
• Exhaust Brake in Cruise: Allows the engine controller to utilize the exhaust brake in cruise control to slow the vehicle down.

• Exhaust Brake Time Delay: The time between when the engine controller would be commanding the exhaust brake ON to when the exhaust brake is actually turned ON.

Vehicle Speed Limit

• Vehicle Speed Limit: Maximum allowable vehicle speed limit.
• Vehicle Speed Output Pulses per Mile: An option to allow the engine controller to transit a square wave signal which represents the actual vehicle speed.
• Tachometer Output Pulses per Engine Revolution: An option to allow the engine controller to transmit a square wave signal which represents the actual engine speed.

Engine Idle Speed

• Base Idle Speed (6H only): This option allows the base idle speed to be raised within a certain range.
• High Idle Speed for Cold (6H only): This option allows the engine speed to be raised for faster.
• Coolant Conditions: Engine coolant warm-up when the engine coolant is below a certain threshold.

Engine Oil Life

• Engine Oil Life Enable (6H only): This option allows the enable or disable of the engine oil change lamp algorithm.
• Engine Oil Capacity (6H only): The option allows the accommodation of additional oil capacity due to the Luber-Finer option.

Engine Shutdown

• Controlled Engine Shutdown: Engine shutdown available due to high engine temperature, low coolant level, or abnormal oil pressure (either high or low oil pressure)
• Engine Protection Counter – Engine Overspeed: Tied to Controlled Engine Shutdown
• Engine Protection Counter – High Exhaust Temp: Tied to Controlled Engine Shutdown
• Engine Protection Counter – High EGR Temp: Tied to Controlled Engine Shutdown
