Caterpillar Monitoring System for Electronic Modular Control Panel Caterpillar

Prior to replacement of a module, ensure that replacement is absolutely necessary. A diagnostic code is seldom caused by the module. Always ensure that the engine code is correct for the engine. Also ensure that the power is available to the main display module. The system voltage is required between the contacts 1 and 2 of the connector for the main display module. To check the engine code, see System Operation, "Harness Code Mode".

Procedure

1. Replace the module.

   1. Turn the ECS to the OFF/RESET position.

   2. Disconnect the engine harness from the module.

   3. Ensure that the module that is replacing the old module has the correct part number.

   4. Install the new module.

      Note: If the main display module that is replacing the old module was previously removed from service, see Testing and Adjusting, "Main Display Module Initialization - Adjust".

   5. Connect the engine harness to the module. On so equipped engines, make sure that the harness code plug is installed.

   6. Turn the ECS to the COOLDOWN/STOP position. Make sure that the module successfully completes the self test: see Testing and Adjusting, "System Self Test".

      Expected Result: The module has been successfully replaced and the module has completed the self test.

      Results:

      • YES - The module has been successfully replaced and has completed the self test. Proceed to 2.

      • NO - The module has been successfully replaced but has not performed the self test properly. Ensure that the module is correct. Ensure that the installation is correct and ensure that no related diagnostic codes are present. STOP.

2. Setup

   1. Set the desired units (English or Metric), see System Operation, "Units Mode".
