HOW TO USE CAT ET TO CHECK THE PROGRAMMING OF THE PARAMETER DEDICATED PTO PARAMETERS

 Remote Switches

1). Use CAT ET to Check the Programming of the Parameter Dedicated PTO Parameters.
→Connect CAT ET to the data link connector.
→Access the Dedicated PTO Parameters on Cat ET. Note the programming of the parameter PTO Configuration (Remote Switches).

2). Check the Circuit for the PTO On/Off Switch.
→Activate the PTO operation.
→Access the CAT ET Status screens that display the following status parameters.
PTO Config (Remote Switches)
PTO On/Off Switch – J1/P1:56

→Verify that each of the interlocks for the PTO are set. Then, while the CAT ET Status screen is being monitored, move the PTO On/Off Switch to the ON and OFF position.

3). Check the Status of the Set/ Resume Input.
→View the Status parameter on CAT ET for the Remote PTO Set Switch – J1/P1:58 and for the Remote PTO Resume Switch – J1/P1:60.
→While the Status screen of CAT ET for the switch is being monitored, perform the following procedure in order:
-Put the Remote PTO Set/Resume Switch in the Set position. The status of the Remote PTO Set Switch – J1/P1:58 changes from “OFF” to set switch “ON” when the Remote PTO Set Switch is moved to the SET position, and the Engine RPM will increase.

-Put the Remote PTO Set/Resume Switch in the Resume position. The Status of the Remote PTO Resume Switch – J1/P1:60 changes from “OFF” to resume switch “ON” when the Remote PTO Resume Switch is moved to the RESUME position, and the Engine RPM will decrease.

-Also monitor the Status of the PTO Set RPM, will changes from 0 RPM to actual Engine Speed (will equal) and the PTO Kickout (Not Kicked Out).

-PTO Kickout value will changes to PTO Switch Turned Off when the PTO On/Off Switch is turned to the “OFF” position.

4). Monitor using the Real Time Graphing while simulate the PTO Configuration Test (Remote Switches).

When the PTO Configuration is programmed to Remote Switches or to Remote Throttle and the PTO On/Off Switch is On, the following circuits are ignored:
• Service Brake Pedal Position Switch 1
• Service Brake Pedal Position Switch 2
• Clutch Pedal Position Switch
• Neutral Switch
• Accelerator Pedal Position Sensor
• Cruise Control Set/Resume Switch that is located in the Cab.

HOW TO USE CAT ET TO CHECK THE PROGRAMMING OF THE PARAMETER DEDICATED PTO PARAMETERS

 Cab Switches

1). Use CAT ET to Check the Programming of the Parameter Dedicated PTO Parameters.
→Connect CAT ET to the data link connector.
→Access the Dedicated PTO Parameters on CAT ET. Note the programming of the parameter PTO Configuration (Cab Switches).

2). Check the Circuit for the PTO On/Off Switch.
→Activate the PTO operation.
→Access the CAT ET Status screens that display the following status parameters.
PTO Config (Cab Switches)
PTO On/Off Switch – J1/P1:56

→Verify that each of the interlocks for the PTO are set. Then, while the CAT ET Status screen is being monitored, move the PTO On/Off Switch to the ON and OFF position.

3). Check the Status of the Cruise Control On/Off Switch. This switch must be ON before Cruise Control or Controlled Idle can be activated. This switch is ON when the switch is closed. When the switch is closed, the following terminals are connected:

P1-5 (AP Sensor/Switch Sensor Common)
P1-59 (Cruise Control On/Off Switch)

→Monitor the status for the Cruise/Idle On-Off Switch – J1/P1:59 while the Cruise Control On/Off Switch is cycled. The correct status for the Cruise/Idle On-Off Switch – J1/P1:59 is “On” when the Cruise Control On/Off Switch is in the ON position, and “Off” when the Cruise Control On/Off Switch is in the OFF position.

4). Check the Status of the Set/Resume Switch.
→Place the Cruise Control On/Off Switch in the ON position.
→Monitor the status for the Cruise Control Set/Resume/Accel/Decel Switch P1-35 & 44 while the Set/Resume Switch is cycled. The correct status for the Cruise Control Set/Resume/Accel/Decel Switch P1-35 & 44 is Set Switch On when the Set/Resume Switch is in the SET position, and Resume Switch On when the Set/Resume Switch is in the RESUME position.

→When PTO On/Off Switch is turned to the “OFF” position, and the Clutch Pedal is depressed, the PTO Kickout value will changes to Clutch Pedal Depressed (before: Not Kicked Out).

5). Monitor using the Real Time Graphing while simulate the PTO Configuration Test (Cab Switches).

When the PTO Configuration is programmed to Cab Switches and the PTO On/Off Switch is ON, the following circuits can be used to interrupt a set RPM:
• Cruise Control Set/Resume Switch
• Service Brake Pedal Position Switch 1
• Service Brake Pedal Position Switch 2
• Clutch Pedal Position Switch
• Neutral Switch
• Cruise Control Pause Switch

JPRO PROFESSIONAL TRUCK DIAGNOSTIC SCAN TOOL

 

JPRO Professional is the #1 in-shop diagnostic and repair solution. With coverage of all makes and models, plus industry-leading bi-directional controls, JPRO helps technicians find and fix all issues on a truck.

JPRO software includes an embedded troubleshooting module, Fault Guidance, and customers have the option to add NextStep Repair（notice ,you need buy nextStep Repair software then could use ）, a repository of repair manuals and step-by-step instructions for repairing fault or symptom-based issues across all engine makes and models.

This release helps techs quickly identify performance and health-related issues on vehicle systems that affect the cost of ownership or could later sideline an otherwise healthy vehicle,”

JPRO’s latest release offers similar user-friendly features and design to help technicians diagnose issues related to coolant, oil, and fuel systems. These interactive screens present live key data points in diagrams to help uncover irregularities, the company says.

It enhanced JPRO’s ability to submit vehicle repair information to third-party databases to create cases and begin warranty submissions. Starting with this release, authorized users can submit information to Trimble’s TMT/TMW service, in addition to existing databases such as Decisiv, Bendix and others. The release also features updated coverage and new bi-directional tests for many major component manufacturers, including emerging advanced driver safety assistance (ADAS) systems.
