SEAL 1P8096 - Caterpillar

Use this procedure if the following diagnostic code is active.
Table 1
J1939 Code and Description Comments
630-2
Calibration Memory : Erratic, Intermittent, or Incorrect The engine Electronic Control Module (ECM) detects that one or more of the programmable parameters have not been programmed.
The ECM may use a default torque map or the ECM may limit the engine to low idle.
The code is active only. The system configuration parameters must be programmed when the application is installed. Perform this programming before the initial engine start-up. Incorrect programming of parameters may lead to complaints about performance and/or to engine damage.Data from a gas analysis is required for determining the correct settings for the fuel quality and for the specific gravity of the gas. The data must be entered into the Caterpillar Software, LERW4485, "Gas Engine Rating Pro (GERP)".If the Electronic Control Module (ECM) is replaced, the appropriate parameters must be copied from the original ECM. This can be done with the "Copy Configuration" feature of Cat® Electronic Technician (ET). Alternatively, the settings can be recorded on paper and then programmed into the new module.Certain parameters are unique for each engine application. Table 2 is a list of the parameters that can be configured for G3600 Engines. The values of the parameters can be viewed on the "Configuration" screen of Cat ET.
Changing the parameters during engine operation can cause the engine to operate erratically. This can cause engine damage.Unless the instructions are different, only change the settings of the parameters when the engine is STOPPED.
