Manufacturer summary

Original wording in English

AN INVESTIGATION OF INHIBITOR SWITCHES (REPLACED FOR DTC P0707) RETURNED TO THE WARRANTY PARTS CENTER HAS IDENTIFIED A HIGH FREQUENCY OF SWITCHES BEING REPLACED WITH “NO TROUBLE FOUND” (NTF). THE MOST LIKELY ROOT CAUSES OF THE P0707 DTC ARE AN OPEN F-18 FUSE OR A STRETCHED AND/OR IMPROPERLY ADJUSTED SHIFT CABLE. IN ORDER TO BETTER SERVICE THE CUSTOMER AND TO STOP THE UNNECESSARY REPLACEMENT OF INHIBITOR SWITCHES, ISUZU RECOMMENDS TECHNICIANS TO FIRST CHECK THE F-18 FUSE, THEN CHECK, AND IF NECESSARY, ADJUST THE SHIFT CABLE BEFORE DIAGNOSING DTC P0707. THE SHIFT CABLE ADJUSTMENT PROCEDURE IS PROVIDED BELOW FOR YOUR REFERENCE. IF ADDITIONAL INFORMATION IS REQUIRED, REFER TO THE APPROPRIATE SERVICE MANUAL.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
