SERVICE INFORMATION
If one or both of the following conditions exist in a 1990-1997 Truck, 1998-2000 Frontier, or 2000 Xterra with KA24 Engine, water may have entered the distributor assembly:
Condition 1: The MIL is "On" with Misfire (P0300 to P0304) Diagnostic Trouble Codes (DTCs) stored in the ECM as a result of moisture in the distributor.
Condition 2: Driveability incidents as a result of moisture in the distributor occur.
A new distributor assembly (with improved drain and distributor cap with improved vent) is available to correct this incident, if it should occur. In addition, if you need to replace the distributor cap for any other reason, the new distributor cap (with improved vent) is available separately and will fit onto the original style distributor assembly body. See the PARTS INFORMATION section of this bulletin for detail.
Use the following SERVICE PROCEDURE to diagnose the condition and replace the distributor assembly.
SERVICE PROCEDURE
1. Verify that Condition 1 and/or Condition 2 above are present.
2. Remove the distributor cap and inspect for traces of water or signs of corrosion caused by water entry.
^ If water entry evidence is not found, investigate other causes for the DTC codes and/or driveability incidents and follow the appropriate Service Manual instructions to repair.
^ If water entry evidence is found, replace the distributor assembly with the appropriate part listed in the PARTS INFORMATION section of this bulletin.
3. Re-set ignition timing to specifications. Refer to the applicable Service Manual for additional details.
