Special Tool(s) New Generation STAR (NGS) Tester or equivalent 418-F048 ( ) 73 Digital Multimeter or equivalent 105-R0051 Inspection and Verification NOTE: The LCM must be reconfigured upon replacement. Refer to the NGS Tester help screen on the configuration card to program the headlamps on with wipers, DRL, and Korean vehicle strategy. 1. Verify the customer concern. 2. Visually inspect for obvious signs of mechanical and electrical damage. Visual Inspection Chart Mechanical Electrical Door ajar switches. Fuse junction panel fuse 28 (10A), 4 (10A), 5 (10A). Power distribution box fuse 6 (60A). Circuitry. Damaged or corroded connectors. Lighting control module (LCM) Driver door module (DDM). Virtual image cluster (VIC). Electronic crash sensor (ECS) module. Low tire pressure module. 3. If the concern remains after the inspection connect the New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If the NGS does not communicate with the vehicle: check that the program card is properly installed. check the connections to the vehicle. check the ignition switch position. 4. If the NGS still does not communicate with the vehicle, refer to the New Generation STAR Tester manual. 5. Perform the DATA LINK DIAGNOSTIC TEST. If the NGS responds with: CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section NO RESP/NOT EQUIP for LCM, go to Pinpoint Test A. SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self test diagnostics for the LCM module. 6. If the DTCs retrieved are related to the concern, go to the LCM Diagnostic Trouble Code (DTC) Index to continue diagnostics. 7.
