33510-93E00 Suzuki CAP, SPARK PLUG

The engine is equipped with an Electronic Control Module (ECM). The ECM contains no moving parts. Follow the troubleshooting procedures in this manual in order to be sure that replacing the ECM will correct the fault. Verify that the suspect ECM is the cause of the fault.Note: Ensure that the ECM is receiving power and that the ECM is properly grounded before replacement of the ECM is attempted. Refer to the schematic diagram.Using a Test ECM
A test ECM can be used in order to determine if the ECM on the engine is faulty. Install a test ECM in place of the suspect ECM. Install the flash file into the test ECM. Program the parameters for the test ECM. The parameters must match the parameters in the suspect ECM. Refer to the following test steps for details. If the test ECM resolves the fault, reconnect the suspect ECM. Verify that the fault returns. If the fault returns, replace the ECM.Use the electronic service tool to read the parameters in the suspect ECM. Record the parameters in the suspect ECM. Install the flash file into the new ECM. After the ECM is installed on the engine, the parameters must be programmed into the new ECM.Note: When a new ECM is not available, you may need to remove an ECM from an engine that is not in service. The ECM must have the same serial number suffix. Ensure that the replacement ECM and the flash file match the suspect ECM. Be sure to record the parameters from the replacement ECM. Use the "Copy Configuration ECM Replacement" function in the electronic service tool.
If the flash file and engine application are not matched, engine damage may result.
Replacement of the ECM
Perform the following procedure in order to replace the ECM.
Connect the electronic service tool to the diagnostic connector.
Use the "Copy Configuration ECM Replacement" function on the electronic service tool. If the "Copy Configuration" is successful, proceed to Step 5. If the "Copy Configuration" failed, proceed to Step 3. Note: Record any logged faults and events.
Record the following parameters:
Record all of the parameters on the "Configuration" screen.
Record all of the parameters on the "Throttle Configuration" screen.
Record all of the parameters on the "Mode Configuration" screen.Note: If the parameters cannot be read, the parameters must be obtained elsewhere. Some parameters are stamped on the engine information plate, but most parameters must be obtained from the TMI data on the Caterpillar Secured Internet.
Remove power from the ECM.
Remove the ECM. Refer to Disassembly and Assembly, "Electronic Control Module - Remove and Install".
Install the replacement ECM. Refer to Disassembly and Assembly, "Electronic Control Module - Remove and Install".
Download the flash file.
Connect the electronic service tool to the diagnostic connector.
Select "WinFlash" from the "Utilities" menu of the electronic service tool.
Select the downloaded flash file.
If necessary, use the electronic service tool to clear the rating interlock. To clear the rating interlock, enter the factory password when the electronic service tool is first connected. Activating the "Test ECM" mode will also clear the rating interlock.
Use the electronic service tool to program the parameters. Perform the following procedure.
If the "Copy Configuration" procedure was successful, use the "Copy Configuration, ECM Replacement" function to load the configuration file into the ECM. Note: During the following procedure, factory passwords may be required.
If the "Copy Configuration" procedure failed, configure the parameters individually. The parameters should match the parameters from step 3.
Check for logged diagnostic codes. Factory passwords are required to clear logged events.
