Fault Condition: This fault will become active when the EMS Module detects that the coolant level switch has experienced a power loss or that the level can not be detected. Engine power may be derated. Possible repairs: Turn the ignition key OFF first. 1) Disconnect the Coolant Level Switch connector. With the coolant filled to the proper level, check for continuity across the two terminals of the Coolant Level Switch. If continuity does not exists, replace the Coolant Level Switch and retest the system.2) Disconnect EMS Module connector B and the Coolant Level Switch connector. Measure for continuity between EMS...

Fault Condition: The Electronic Malfunction Lamp (EML) will illuminate when the Crankcase Pressure (CP) Sensor signal line voltage is less than 0.3 volts or greater than 4.75 volts. If the signal line voltage is between 0.3 volts and 4.75 volts the fault will become inactive. Possible repairs: Turn the ignition key OFF first. 1) Check for continuity between Crankcase Pressure (CP) Sensor harness connector pin 2 (signal line) and a good ground. If continuity exists, locate and repair the short circuit to ground.2) Disconnect EMS Module connector B. Check for continuity between Crankcase Pressure (CP) Sensor harness connector pin 1...
