DESCRIPTION:

The 2001-2005 MY XG300/350 and Santa Fe 3.5L incorporate an Electronic Throttle control System (ETS).

NOTE: Please see TSB 05-36-002 for a general description of the system, its components and the INITIALIZATION procedure.

The list of DTC codes has been modified. This TSB lists and explains the updated Diagnostic Trouble Codes (DTC) related to the ETS system.

NOTE: Some diagnostic trouble codes (DTCs) for 2004-2005 MY Santa Fe 3.5L and 2004-2005 XG350 vehicles have been added and revised. TSB 04-36-013 provides the newly added and revised DTCs in addition to the diagnostic procedures for these DTCs.

NOTES:

In most cases, an ETS related DTC will set in pairs of codes. The first code denotes the related system or component. The second code is for the specific fault detected.

- Generally, an ETS related fault will cause the CHECK ENGINE LIGHT to illuminate immediately after detection (does not require two trips).

- when repairing a vehicle for ETS related codes, refer to the appropriate sections of the ETM and Shop Manual.


EXAMPLE: P1118 & P1178. The first code is to signify that the fault is related to the ETS Motor. The second code, P1178, signifies that there is an electrical open circuit. Thus, the power to the ETS Motor may be interrupted.
