Simplified Schematic For The Engine Control Switch (ECS)
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 negative terminal "B−". At any time, only one of these four positions (inputs) is connected to the battery negative terminal "B−".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 from the ECS. The jumper electrically connects terminal "6" to terminal "9"."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 maintains rated speed for the 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.
None of the GSC+ inputs from the ECS are connected to ground.
More than one of the GSC+ inputs from the ECS is connected to the battery negative ("B−") at the same time. The one exception is the start input. The start input of the GSC+ is also connected to the remote start/stop initiate contact. The contact is controlled by the customer. The GSC+ will then accept a connection from the battery negative at the start input. Other inputs from the ECS are also received.The CID 0336 FMI 02 is the only ECS diagnostic code that is detected by the GSC+. Clear the diagnostic code from the fault log after troubleshooting is complete. The GSC+ treats a CID 0336 FMI 02 as a shutdown fault. Use these procedures for an active diagnostic code or an inactive diagnostic code.Test Step 1. CHECK FOR AN OPEN CIRCUIT IN THE "OFF/RESET" POSITION
If equipped, disconnect the remote start/stop initiate contacts from the terminal strip in the customer connection box.
Disconnect the harness connector from the GSC+.
Check whether the corresponding contact of the GSC+ harness connector is the only contact that is connected to the battery negative.
At the GSC+ harness connector, measure the resistance from contact "39" to the "B−" terminal of the relay module. Measure the resistance from contacts "32", "33" and "40" to the "B−" terminal. Make a note of the resistances that are measured. Expected Result:The resistance that is measured from contact "39" to the "B−" terminal of the relay module should be 5 ohms or less. The resistance that is measured from contacts "32", "33" and "40" to the "B−" terminal should be greater than 5000 ohms.Results:
OK - All
