CAT 86013943 Controller

The CAT 86013943 is a chassis control module used in New Holland tractors such as the 8870 series, providing power‑train and hydraulic command functions. Common failure points for this class of units include burned or tripped fuses on the main power rail, damaged surface‑mount ICs due to vibration or overheating, and degraded solder joints on critical signal lines. First‑check diagnostics: verify 48 V supply voltage at the module input, inspect all connectors for corrosion or loose pins, and review any stored fault codes via the tractor’s diagnostic port before proceeding with component replacement.[oss-gpt-20b]
