INTERMITTENT MIL ON WITH NO FAULT CODE STORED -
INFORMATION ABOUT DTC P1330
This bulletin provides information relating to Sorento (BL) 3.5L 2003-2006MY Sedona (GQ) 3.5L 2002-2005MY, Optima (MS) 2.4L 2001-2006MY,
Amanti (GH) 3.5L 2004-2006MY vehicles. In affected vehicles an intermittent short to ground in a circuit only intended for testing purposes may cause
the MIL to illuminate and a DTC P1330 (Spark Timing Adjust) to be stored. As soon as the fault disappears the MIL may turn off and the fault code can
also be immediately erased by the engine management system making it hard to diagnose the concern.
DTC P1330 is intended to be triggered when specific terminals in the Multi-purpose Data Link/Check connector are grounded. When these terminals are
grounded a default control mode is temporarily activated in which the spark timing is fixed. This function is intended to only be used during certain
checks on the vehicle assembly line. To ensure that vehicles do not leave the assembly plant in this (spark timing fixed) condition a P1330 DTC will set
and illuminate the MIL whenever this function is active. However reports from in-use vehicles have indicated that the same condition can occur when
these terminals and/or associated wiring are shorted to ground as a result of an electrical fault thus setting the P1330 code and illuminating the MIL.
When diagnosing a complaint of (intermittent) MIL illumination with no DTCs present first check for freeze frame data. If the cause was due to a fault
detected by the DTC P1330 logic freeze frame data should still be available and indicate that P1330 was the DTC that caused the freeze frame data to be
stored. To diagnose and repair a P1330 fault inspect related connectors or wiring harness and repair as necessary following the instructions in this
bulletin.
