Technical Service Bulletin #

Date:

MIL ON, Hex Code $73 Set
NO: 18-03-98
GROUP: Vehicle Performance
DATE: Feb. 6, 1998
SUBJECT:
Power Steering Switch Elimination And/Or MIL Illumination With Hex Code $73
MODELS:
1998 (LH) Concorde/Intrepid
NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 3.2L ENGINE.
DISCUSSION:
An early running change was made to eliminate the power steering switch input to the PCM. This change was made due to a premature power steering
switch electrical fault. The switch at the power steering pump was changed to a dummy switch (plug) and a PCM (flash) change was made to prevent
DTC $73 - POWER STEERING SWITCH FAILURE.
Although a rework effort took place to implement this change in all vehicles prior to dealer shipment, a few vehicles may have been released without
having the total rework completed.
If a vehicle is brought in with MIL illumination and DTC Hex $73 - POWER STEERING SWITCH FAILURE the power steering pump must be
inspected for dummy switch installation and the PCM must be checked for the latest software version based on the TIL release listed on this Technical
Service Bulletin.
NOTE:
UNDER NO CIRCUMSTANCES SHOULD THE DUMMY SWITCH BE REPLACED WITH AN OPERABLE SWITCH.
DIAGNOSIS:
Using the Mopar Diagnostic System (MDS) or the Diagnostic Scan Tool (DRB III) with the appropriate Diagnostic Procedures Manual, verify all
engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as
necessary
before proceeding further with this bulletin. If DTC Hex $73 is present, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN CONTROL MODULE (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE
REPLACEMENT CONTROLLER SHOULD BE VERIFIED FOR THE LATEST REVISION LEVEL. USE THE FLASH PROCEDURE TO
UPDATE REPLACED CONTROLLERS AS NECESSARY.
