Conditions for diagnostic trouble code (DTC)
The voltage at pin A14.EA:4 is less than 4V

Diagnostic operating conditions
Ignition key in ON position

Observable symptoms
Engine overheating

Probable cause
1) Coolant pump
2) Short circuit to ground
3) Connector
4) Wiring harness
5) Engine Control Module (ECM)
