Has automatic trans. While problem is occurring, if the shift lever is put in any gear, it stops cranking. This verifies that the short is on the ignition switch side of the Transmission Range sensor (or in the sensor). Gave circuit description. Check for signs of water in the inside fusebox or water in the wiring harness near C103 (16 terminal connector at the rear of driver's side fender apron, gas engine only). Pull fuse 20 out of the inside fusebox. If the engine stops cranking, the short is from there towards the ignition switch. Tech called back - still cranks when he pulls fuse 20. While problem is occurring, disconnect Transmission Range sensor and check the WHT/PK wire for voltage. If it has battery voltage, work back towards the inside fuse box through connectors. Tech called back - has power on the WHT/PK wire in the TR sensor connector with the sensor disconnected. If you disconnect C103, it has power on the WHT/PK wire in the side going towards the fusebox. The short is in the fusebox or in the wire between the fusebox and C103. While problem is occurring, disconnect the wire at pin 4 of C242b on the rear of the fusebox. If it goes away, replace the fusebox and check for a leaking windshield.

This article supersedes TSB 02-19-4 to update the service procedures and service part information.

ISSUE:

Some 1999-2003 SuperDuty and Excursion vehicles may exhibit the condition of starter staying engaged after releasing key from start position, repeat starter failure or a sticking/binding ignition lock cylinder. This may be due to:

An Ignition Lock Cylinder Binding Not Fully Returning From Start To Run

Short Condition On Starter Relay Circuit 113 (YE/LB) Or 1093 (TN/RD)

Sticking Starter Relay

An Internal Short In The Power Distribution Junction Box (PDJB)

ACTION:

If one of these conditions occur, inspect the starter and flywheel for damage and replace as necessary. Inspect the starter circuit for shorts including the Power Distribution Junction Box (PDJB) and verify proper cylinder lock function. Service as necessary. Use the following procedure to diagnose the starter circuit and system components.

SERVICE PROCEDURE

To check for short in the starter relay circuit 113:

Check terminal #2 at starter relay for voltage with key in run position (move key from "OFF" to "RUN") with the engine off. If voltage is present, locate and repair short. If no short detected, continue with Step 2.

With starter relay terminal #2 removed and vehicle in park, monitor voltage at starter relay terminal after cycling ignition from START to RUN (Do not assist key back to run position).

If voltage is present after cycling key returns to Run position, Connect NGS/WDS or Scan Tool and monitor PIDS. Check for KEY_START and KEY_RUN. If the KEY_RUN PID is not seen after any KEY_START PID, the ignition cylinder lock is seizing and must be replaced.

For 1999-2001 vehicles, access the GEM (Generic Electronic Module) to view PIDS

For 2002-2003 vehicles, access the HEC (Hybrid Electronic Cluster) to view PIDS.

If key check is functioning properly and voltage is still present, check the starter relay for sticking by swapping with a known good relay and repeat Step 2.

NOTE: IF ALL OF THE ABOVE CONDITIONS ARE VERIFIED FOR PROPER OPERATION, THE ISSUE MAY BE CAUSED BY AN INTERMITTENT BINDING CONDITION IN THE IGNITION CYLINDER LOCK. PROCEED WITH REPLACEMENT OF IGNITION SWITCH LOCK CYLINDER (11582).

IGNITION SWITCH LOCK CYLINDER REPLACEMENT PROCEDURE

Disconnect the battery ground cable and wait at least one minute.

Insert the ignition key and turn it to the RUN position.

Insert a punch into the access hole (located in the lower steering column shroud, below the lock cylinder) and press the release button while pulling out the ignition switch lock cylinder.

NOTE: SOME VEHICLES DO NOT HAVE AN ACCESS HOLE AND REQUIRE LOWER SHROUD REMOVAL. REFER TO THE APPROPRIATE MODEL WORKSHOP MANUAL, IGNITION SWITCH LOCK CYLINDER REMOVAL AND INSTALLATION SECTION 211 IF ADDITIONAL DETAIL IS REQUIRED.

Install new Ignition Lock Cylinder and verify proper function.
