In most cases, powertrain movement will duplicate the issue, such as, shifting
between drive and reverse, accelerating, braking or just driving.
Cause
These concerns could be caused by the engine wiring harness rubbing on the front
corner of the left hand cylinder head (1) or drive belt idler bracket and shorting any
number of circuits to ground, see pictures below. Due to the number of circuits in
the harness, there is a wide variety of di erent symptoms that could occur
depending on which circuit(s) are damaged.
Correction:
To correct this concern, repair the damaged wiring following the SI wire-to-wire repair procedures. Once
repaired, protect and reposition the engine wiring harness to prevent future harness damage.
Warranty Information
For wiring repairs covered under warranty, please refer to latest version of bulletin 10-00-89-005 for warranty
information on wire/connector repairs.
