Other     "Wait to Start Lamp"     "Fast Idle Lamp"    When the "Truck Manufacturer" parameter is programmed to "GM" the "Output #9" (Warning Lamp) is used with the standard Caterpillar Engine Monitoring system. With SEP00 and newer Personality Modules, "Output #9" can be configured to only activate when the ECM detects high engine coolant temperature. The "Engine Monitoring Lamps" parameter can be programmed to "Warning Lamp" for normal operation with the Engine Monitoring system. This is the default option. The "Engine Monitoring Lamps" parameter can also be programmed to the "High Coolant Temp Warning Lamp" option. In this configuration, the ECM will only provide an indication of high coolant temperature. This setting allows the ECM to interface with the Vehicle Shutdown System. When this setting is used, the warning lamp will not be available for normal use with the Caterpillar Engine Monitoring System.When the ECM is configured for the "High Coolant Temp Warning Lamp" option, the output for the warning lamp (terminal 29) will be connected to the vehicle shutdown module. The ECM will provide a ground path at terminal 29, if a high coolant temperature is detected. If a ground path is present at the ECM output for the warning lamp (terminal 29), the vehicle shutdown module will disrupt keyswitch power to the ECM. This will cause the engine to shut down. The ECM will only pull terminal 29 to ground when all of the following conditions are present:
"Truck Manufacturer" parameter is programmed to "GM".
"Engine Monitoring Mode" parameter is not programmed to "OFF".
"Engine Monitoring Lamps" parameter is programmed to "High Coolant Temp Warning Lamp".
The engine has been running for a minimum of 30 seconds.
The coolant temperature sensor circuit has no open circuit faults that are active.
The coolant temperature sensor circuit has no short circuit faults that are active.
The coolant temperature is at 113 °C (235 °F) or above 113 °C (235 °F) for four seconds.Note: If the circuit for terminal 29 is shorted to ground in the wiring harness, the vehicle shutdown module will shut down the engine.After a ground has been detected for two seconds, the vehicle shutdown module will alert the driver of an impending shutdown. A "Check Gauges" message and an audible tone will be present for approximately 25 seconds. A second tone will then sound when the vehicle shutdown module removes keyswitch power from the ECM input. When the keyswitch power is removed from the ECM input, the engine will shut down. Note: When the "High Coolant Temp Warning Lamp" feature is utilized, the other Caterpillar engine monitoring features are not available to shut down the engine. The vehicle shutdown module may provide similar functions."Fast Idle Enabled Lamp"OCT01 and newer Personality Modules.This parameter configures the ECM to turn on a lamp that is connected to output J1/P1:31 or to output J1/P1:21 when fast idle operation is active. To use this feature, a momentary switch must be connected to input #18 (J1/P1:40) and the parameter "Fast Idle RPM #1" must be programmed to a valid speed that is above low idle.

"Fast Idle Enabled Lamp" must be programmed to "J1/P1:21" for this feature to be used.

Alternatives     Default    
"J1/P1:31"     "NONE"    "PTO Switch On Lamp"OCT01 and newer Personality Modules.This parameter configures the ECM to turn on a lamp that is connected to output J1/P1:30 when the engine is in PTO mode.

Alternatives     Default    
"NONE"     "J1/P1:30"    "Change Oil Lamp"OCT01 and newer Personality Modules.This parameter configures the ECM to turn on a lamp that is connected to output J1/P1:30 when the programmed maintenance parameters indicate that an oil change is needed.

"NONE"     "J1/P1:30"    "Fan Control Type"Personality Modules prior to JUN01.If the ECM is used to operate the cooling fan, this parameter must be programmed to the "On/Off". This parameter should be programmed to "NONE" if the ECM is not connected to the cooling fan relay or the cooling fan solenoid. Also, this parameter should be programmed to "NONE" if the ECM is not operating the cooling fan relay or the cooling fan solenoid. When this parameter is programmed to "NONE", the service technician can use Cat ET to determine that the ECM is not connected to the fan circuit.

"On/Off"     "NONE"    "Fan Control Type"OCT01 and newer Personality Modules.If the ECM is used to operate the cooling fan, this parameter must be programmed to the "On/Off" or one of the optional parameters. This parameter should be programmed to "NONE" if the ECM is not connected to the cooling fan relay or the cooling fan solenoid. Also, this parameter should be programmed to "NONE" if the ECM is not operating the cooling fan relay or the cooling fan solenoid. When this parameter is programmed to "NONE", the service technician can use Cat ET to determine that the ECM is not connected to the fan circuit.
