THE ECO-GOVERNOR CHECKLIST No.
I/O
Design
Control system design and check 1 Is alternator’s charging capacity enough? Besides starting aid, E-ECU, Eco-governor (pump, CSD), EGR valve, E-ECU lamp, and E-ECU relay require 4 - 5A consumption current for the engine control. 2 Is the E-ECU’s connector installed facing downward? Avoid the installation method that makes water trapped inside coupler in ECU side or water trapped in coupler in harness side ? it may cause the connector terminal to rust. 3 Is the E-ECU installed in a location that is well ventilated and not subject to direct sunlight? it will result in malfunction by high temperature and discoloration by sunlight. 4 Is the E-ECU installed in a location that is not subject to steam or high-pressure water for cleaning? It will result in connection malfunction and make connector terminal to rust. 5 When the salt damage is thought, is the salt damage prevention cover installed in the E-ECU? When the aluminum part of the E-ECU becomes rusty, it will result in malfunction such as flaking off molding. 6 Is the engine trouble indication means (the trouble monitor lamp, etc.) located so as to be easily visible to the operator. The engine performance is not assured at the trouble conditions (flash of the trouble monitor lamp, etc.). 7 Is the connector for the engine diagnosis tool located so as to be easily maintained? The connector for the engine diagnosis tool is essential for the E-ECU’s maintenance. 8 Is the E-ECU located where the regulatory environmental conditions are satisfied? (See the installation assessment report for environmental requirements). 9 Is the accelerator sensor located where the regulatory environmental conditions are satisfied? (See the installation assessment report for environmental requirements). Never install the Bobcat genuine accelerator sensor (129938-77800) to engine or fuel injection pump body. 10 Are the engine type and manufacturing number matching the engine nameplate and E-ECU label? The engine performance is not assured except the regulated combination. 11 Is the trouble monitor lamp flashing after the 2 seconds illumination at the time of turning on the key switch? (When the other engine trouble indication means besides the trouble monitor lamp are utilize, is there the trouble indication by that means?) The engine performance is not assured at the trouble conditions (flash of the trouble monitor lamp, etc.). 12 Is the engine diagnosis tool in operation? 13
14
Is the E-ECU power voltage at the time of getting over cranking increase to more than 6.0 V by measuring between the VB terminal (E48) and the GND terminal (E45)? Especially, the evaluation at cold start and battery degradation is requested. In the engine run conditions, low idling, high idling, rated load, middle load, check the following. Check is conducted by using the engine diagnosis tool. • Engine speed fluctuation: the difference between maximum and minimum value of the engine speed in 10s. • Rack deviation: the difference in average value of target rack position and actual rack position in 10s. • Rack deviation: the difference in average value as well as maximum and minimum value of target rack position and actual rack position in 10s. (Report the result to Bobcat. The judgment is made by Bobcat).
