PIN-SPRING 3H9675 - Caterpillar

System Operation Description:The engine control switch (ECS) is used by the operator for manually controlling the engine. The ECS has four positions and each position connects to a corresponding input of the GSC+. The selected position of the ECS connects the corresponding input of the GSC+ to the -Battery terminal. At any time, only one of these four positions (inputs) is connected to the -Battery terminal.Each position of the ECS places the engine in a different mode. The four positions and the corresponding modes are described in the following paragraphs."OFF/RESET" - The engine is shut down and the GSC+ is reset. The upper display and fault indicators on the left side are temporarily cleared. The GSC+ turns OFF unless a jumper is installed at the ECS. The jumper electrically connects terminal "6" to terminal "9" on the ECS."AUTO" - The engine starts and the engine runs when the remote start/stop initiate contact closes the start input that is located on the GSC+. The GSC+ closes the remote start/stop initiate contact to the battery negative terminal "B-". Also, the engine starts and the engine runs when the customer communication module (CCM) sends a remote start command. At this time, the GSC+ starts the engine. The engine runs normally until the remote start/stop initiate contact opens. Also, the engine runs normally until the customer communication module (CCM) sends a remote stop command. The engine enters a cooldown period. After the cooldown period, the engine is shut down. The GSC+ shows diagnostic codes on the upper display and on the fault indicators as the diagnostic code occurs. The GSC+ is ON with the ECS in this position."MAN/START" - The engine starts and the engine runs until the operator turns the ECS to the "OFF/RESET" or the "COOLDOWN/STOP". The engine starts and the engine runs until the GSC+ detects a shutdown fault. The GSC+ shows diagnostic codes on the upper display and on the fault indicators as the diagnostic code occurs. The GSC+ is ON with the ECS in this position."COOLDOWN/STOP" - The engine enters a cooldown period. The cooldown period is programmable from 0 to 30 minutes. After the cooldown period elapses, the engine is shut down. The GSC+ shows diagnostic codes on the upper display and on the fault indicators as the diagnostic code occurs. The GSC+ is ON with the ECS in this position.Note: The remote start/stop contact is connected to the GSC+ start input via a terminal strip. Wire number 57 makes the connection from the terminal strip to the GSC+ start input. Before troubleshooting, disconnect the remote start/stop initiate contacts from the terminal strip.Note: Diagnostic codes are created when the harness connector is disconnected from the GSC+ during these troubleshooting procedures. Clear these created diagnostic codes after the particular problem is corrected and the particular diagnostic code is cleared. The possible causes of a CID 0336 FMI 02 are listed below.
