Recommended Actions
Note: If a kickout occurred, the ECM stores the most recent cause of the kickout. However, the ECM will not store the information if the ECM is powered down. The ECM is powered down when the keyswitch is placed in the OFF position. It may be necessary to operate the vehicle in order to duplicate the problem. Then, check the value of the "Cruise Kickout", the "Idle Kickout", or the "PTO Kickout" status parameter before the ECM is powered down.Perform the actions that relate to the feature that has the complaint.Check the Programmable Parameters
Refer to Table 1. Use the Caterpillar Electronic Technician (ET) to verify that configuration parameters for the feature with the complaint are programmed correctly:
Table 1
Parameters for the Features
Feature Configuration Parameters Notes
Cruise Control Low Cruise Control Set Speed Limit If the vehicle speed is below the "Low Cruise Control Set Speed Limit", the cruise control can not be set or resumed.
High Cruise Control Set Speed Limit If the vehicle speed exceeds the "High Cruise Control Set Speed Limit" and the driver attempts to set a cruise control speed, the cruise set speed will be the "High Cruise Control Set Speed Limit".
Transmission Neutral Switch
Cruise Control On/Off Switch
Cruise Control Set/Resume/Accel/Decel Switch
Cruise Control Pause Switch
Extended Idle Idle Vehicle Speed Limit If the driver attempts to set an idle engine rpm and the vehicle speed exceeds the "Idle Vehicle Speed Limit", the idle will not activate.
Idle RPM Limit If the engine rpm is above the "Idle RPM Limit" and the driver attempts to set an idle engine rpm, the idle engine rpm will be the idle rpm limit.
Transmission Neutral Switch
Cruise Control On/Off Switch
Cruise Control Set/Resume/Accel/Decel Switch
Cruise Control Pause Switch
PTO PTO Top Engine Limit
PTO Kickout Vehicle Speed Limit If the vehicle speed exceeds the programmed "PTO Kickout Vehicle Speed Limit", the ECM will not maintain the set speed.
Transmission Neutral Switch
PTO On/Off Switch
Remote PTO Set Switch
Remote PTO Resume Switch Check the Switches
Typically, the operation of the PTO requires an interlock switch such as a parking brake switch. Ensure that all interlocks are set to allow PTO operation.Cat ET uses the following status parameters to display the most recent cause of the rubbing: "Cruise Kickout", "Idle Kickout" and "PTO Kickout". Check the cause of the kick out.If the cause of the kick out is "Switch Turned Off", the ECM has detected an open circuit in the circuit for the cruise switch or the PTO switch. Verify that the operator did not turn off the switch. Use Cat ET to check the status of the on/off switch while the switch is operated. Refer to Troubleshooting, "Cruise Control Switch Circuit - Test" or Troubleshooting, "PTO Switch Circuit - Test", if necessary.If the cause of the kick out is "Brake", the ECM has detected an open circuit in the circuit for a service brake switch. Verify that the operator did not operate the service brake. Use Cat ET to check the status of the service brake switches while the service brake is operated. Refer to Troubleshooting, "Service Brake Pedal Position (Switch 1) Circuit - Test" or , "Service Brake Pedal Position (Switch 2) Circuit - Test", if necessary.If the cause of the kick out is "Clutch", the ECM has detected an open circuit in the circuit for the clutch switch. Verify that the operator did not operate the clutch. Use Cat ET to check the status of the clutch switch while the clutch is operated. Refer to Troubleshooting, "Clutch Pedal Position Switch Circuit - Test", if necessary.If the cause of the kick out is "Neutral", the ECM has detected an open circuit in the circuit for the transmission neutral switch. Verify that the operator did not shift the transmission into neutral. Use Cat ET to check the status of the transmission neutral switch while the transmission is shifted into neutral. Refer to Troubleshooting, "Neutral Switch Circuit - Test", if necessary.If the cause of the kick out is "Set SW Timeout", then the cruise control set/resume switch was placed to the "Set" position by the operator for more than 15 seconds or there is a short circuit in the circuit for the "Set" position of the switch. Determine the condition that caused the kickout. Refer to Troubleshooting, "Cruise Control Switch Circuit - Test", if necessary. Turn off the cruise control switch and turn on the cruise control switch in order to get the cruise control to work again.If the cause of the kick out is "Res SW Timeout", then the cruise control set/resume switch was placed to the "Resume" position by the operator for more than 15 seconds or there is a short circuit in the circuit for the "Resume" position of the switch. Determine the condition that caused the kickout. Refer to Troubleshooting, "Cruise Control Switch Circuit - Test", if necessary. Turn off the cruise control switch and turn on the cruise control switch in order to get the cruise control to work again.If the cause of the kick out is "Vehicle Speed < Limit", the vehicle speed signal exceeded the programmed Idle/PTO vehicle speed limit or the vehicle speed signal is missing or erratic. Perform the following steps:
Inspect the vehicle speed sensor for debris.
Carefully inspect the vehicle's electrical connectors for the speed circuit. Look for corrosion, for debris, and for loose terminals.
Check the P1 connector for corrosion, for debris, and for loose terminals.
Use Cat ET to check the vehicle speed while the vehicle is parked. Also check the vehicle speed while the vehicle is being driven in order to determine that the vehicle speed that is indicated by Cat ET does not vary significantly from the vehicle speed that is indicated by the speedometer. Refer to Troubleshooting, "Vehicle Speed and Speedometer Circuit - Test". Check the Clutch Switch and the Clutch Spring
Check the clutch switch adjustment and the clutch spring. Make repairs, if necessary.Check the Power Connections to the ECM
A problem with the power wiring to the ECM can cause erratic engine operation. If this is a suspected cause, refer to Troubleshooting, "Ignition
