Some vehicles may exhibit a rough idle, Anti-lock Brake System (ABS) warning lamp illumination, inoperative or erratic speedometer, Diagnostic Trouble Codes (DTCs) P0500, P0501, P0503, P1721, P0176, P1000, ABS DTC 9, RABS DTC 16, or a delayed or harsh shifting automatic transmission. This may be caused by water intrusion at connector C309 (2000 model year) or C340 (2001 model year) under the driver's seat.
Inspect affected connectors; clean or replace connector pins as necessary. Install new sleeve and boot assembly over -14401- connector (interior). Refer to the following Service Procedure for details.
Verify water intrusion in connector C309 for 2000 model year or C340 for 2001 model year applications by removing bottom half (male) connector located on -14405- wire harness assembly under driver's seat, outside, beneath vehicle's cab. If water is present or pins are damaged, remove connector sleeve and perform the following:
F67Z-14487-AA replacing silver finish pins (1.6mm) and/or E6DZ-14487-AA replacing gold/brass finish pins (1.6mm) and/or F6DZ-14487-BA replacing gold/brass finish pins (2.8mm).
E7EB-14461-BA replacing silver finish pins (1.6mm) and/or F6TZ-14461-AA replacing gold/brass finish pins (1.6mm) and/or F6DZ-14461-CA replacing silver finish pins (2.8mm) and/or E5DZ-14461-A replacing silver finish (1.6mm Circuits 52 and 64)
After connector has been reinstalled, verify concern has been eliminated. Reinstall carpet or vinyl lining, door scuff plate, and driver's seat.
