SUBJECT: EMCPII+ Wall-Mounted Panel Schematics
PROBLEM:
The 200-8977 Wiring Schematics (versions 00 through 03) show incorrect customer pin connections. On page 9 of the 200-8977 Wiring Schematics (versions 00 through 03), the following terminals for the Wall-Mounted EMCPII+ panel are labeled incorrectly:
- Engine coolant level
- Coolant temperature
- Oil Pressure
Incorrect Customer Pin Connections
The 200-8977 Wiring Schematics (versions 00 through 03) incorrectly show the customer connections between the engine connector and the wall-mounted panel as follows:
- Pin 38 to Terminal 33
- Pin 39 to Terminal 34
- Pin 40 to Terminal 36
Connecting the panel in this fashion can generate faults to be displayed in the control panel.
SOLUTION:
The 200-8977 (version 04) Wiring Schematic has been updated to show the correct terminal designation. Version 04 of the 200-8977 Wiring Schematic was released in April 2003.
Correct Customer Pin Connections
The 200-8977 Wiring Schematic (version 04) shows the correct customer connections between the engine connector and the wall-mounted panel as follows:
- Pin 38 to Terminal 36
- Pin 39 to Terminal 33
- Pin 40 to Terminal 34
The 200-8977 Wiring Schematic (version 04 or higher) can be found on the Caterpillar XREF Program. The Caterpillar XREF Program can be found at the following URL:
