DTC P1330 DIAGNOSTIC INFORMATION
DESCRIPTION:
This bulletin provides a general description and diagnostic information for DTC P1330
(Spark Timing Adjust) on vehicles equipped with Melco engine management system.
APPLICABLE VEHICLES:
^ 1999 - 2005 Sonata (EF) 2.4L
^ 2001 - 2004 Santa Fe (SM) 2.4L
^ 2003 - 2006 Santa Fe (SM) 3.5L
^ 2001 - 2005 XG300/XG350
SERVICE PROCEDURE:
DEFINITION OF DTC P1330:
1. Name: Spark Timing Adjustment.
2. Detecting Conditions:
Diagnostic Code P1330 is a temporary diagnostic code that is set when the "Spark Timing Adjusting" terminal of the PCM is grounded. This pin is grounded through the vehicle's Multipurpose Check Connector during vehicle assembly for engine calibration purposes, and its function is not intended to be used during service or troubleshooting of the vehicle. The code is automatically cleared when the "Spark Timing Adjusting" terminal is removed from the ground connection. When diagnosing a vehicle with a DTC P1330 stored in the PCM, verify the "Spark Timing Adjusting" terminal of the PCM and the harness between the PCM and the vehicle's Multipurpose Check Connector are not grounded.
3. Effect on OBD System:
P1330 does not affect OBD-related Systems or monitors.
4. Fault Code Storage/Erase, MIL illumination and Freeze Frame storage erase:
a. Pending fault code: It does not store.
b. Confirmed fault code and freeze frame storage / MIL illumination:
Immediately after fault detected, fault code and freeze frame data are stored and MIL illuminates
c. Confirmed fault code erase and MIL cleared: Immediately after fault fixed, fault code will erase and MIL is cleared.
d. Freeze frame data erase: The freeze frame data is erased only by a scantool command.
5. Repair Procedures:
If diagnosing a complaint of intermittent or recent MIL illumination with no DTCs present, check freeze frame data. If the cause was due to a fault detected by P1330, freeze frame information should still be available and indicate that P1330 was the DIG that caused the freeze frame data to be stored.
To diagnose and repair a P1330 fault, inspect related connector or wiring harness. 5-1): Data Link/Check Connector Terminal and Connector inspection:
a. Thoroughly check the connector for corrosion, bending, contamination, deterioration or damage.
b. If any problem is found, repair or change the connector and coat with a contact grease, then firmly reconnect the connector completely.
5-2): Control Module Wiring Harness inspection
a. Ignition Off.
b. Disconnect connector to the engine control module (or powertrain control module or engine/transaxle control module as directed by the following diagrams for each vehicle.
c. Measure resistance between identified terminal of data link/check connector and chassis ground and between identified terminal of wiring harness side of each control module and chassis ground. (Refer to the following diagram for each vehicle).
d. If measured resistance is below 1000 Ohm, harness is shorted to ground. Repair or replace the harness as necessary.
NOTE:
All model's harness and connector information are reported in the drawings below.
5-3): Verification after repair
a. Ignition On
b. Using a Scan tool, clear the DTCs and freeze frame data.
c. Turn on the vehicle and keep the idle state for 2-3 minutes.
d. Check the MIL and DTC/freeze frame data once again. Make sure MIL is not illuminated and that the P1330 DTC and associated freeze frame data are not stored.
