6. MPX System • Troubleshooting procedure • NOTICE: • DTCs for CAN system: U0073, U0100 and U0129 • Refer to troubleshooting section for each system if DTCs regarding CAN system is not output • Turn IG switch off before measuring the resistances of CAN main wires and branch wires • After the IG switch off, check that key reminder warning system and light reminder warning system are not in operation • Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the IG switch, any other switches or the doors. If doors need to be opened in order to check connectors, open the doors and leave them open HINT: Operating IG switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.

7. MPX System • Troubleshooting procedure • Check CAN bus line (resistance check, short or open) • Check installed systems (ECU & Sensors) that adopt CAN communication • Check and Clear DTCs • Check CAN communication using Intelligent Tester II • System (ECUs & Sensors) that adopt CAN communication vary depending on the vehicle and option setting. • Non-installed ECUs or sensors are not displayed. DO NOT mistake them for being in communication stop mode. • If two or more ECUs or sensors are not displayed on IT, perform troubleshooting for open in one side of CAN branch wire for each undisplayed ECU or sensor (Open circuit in CAN branch wire) • DTC Combination table • Confirm trouble according to the combination of output DTCs regarding the CAN communication system (Previous DTCs maybe the cause, if all ECUs and sensors are displayed on IT during “Bus Check”). • Inspect circuit • Identify problem • Repair or Replace • Confirmation test • End.

20. Service Points: Initialization Initialize the system when headlight beam level control ECU is replaced or height control sensor is removed or rear suspension has been replaced Adjust headlight aim after initialization If there is malfunction, perform troubleshooting before initialization Lighting System • A. Preparation: • Unload the trunk and vehicle, check spare tire, tools and jack in their original positions • No passenger in the vehicle • Turn off headlight • Stop the vehicle in a level surface and keep the vehicle height unchanged

21. Lighting System • Service Points: Initialization • B. Check Warning Light: • Turn IG ON, check the warning light according to table below • HINTS: • If the warning light does not come ON when turn IG on, inspect and repair according PROBLEM SYMPTOMS TABLE (see Repair Manual) • When warning lights blinks, the pattern is repeated at 1.25 second interval until the ignition switch is turned OFF

22. Service Points: Initialization Lighting System • C. Initialization: • Check fuel level of fuel receiver gauge in the combination meter • Connect terminal 4 (CG) and 8 (OP3) of DLC3 using SST

23. Lighting System • Service Points: Initialization • Start operating light control switch within 20 seconds of connecting terminal (DLC3). Flash the headlight in accordance with the table below: • HINT: • A Range: When no. 1 segment blinks, the blinking pattern is repeated 0.6 second intervals (see illustration 1) • B* Range: When no. 1 segment blinks, the blinking pattern is repeated 1.2 seconds interval (see illustration 2) • NOTICE: • Turn the low beam headlights on or off at approx. 1 sec interval • Be sure to operate the light control switch from outside the vehicle

24. Service Points: Initialization Lighting System • Check that the warning lights blinks in accordance with the table below

25. Lighting System • Service Points: Initialization • HINT: • When the warning light blinks, blinking pattern is repeated 1.25 second intervals until ignition switch is turned OFF • If the calculate vehicle height is not between full-bound and full-rebound, the height control sensor initialization will not be completed, and the warning light will blink as shown in the illustration 3. In this case, disconnect SST from DLC3, turn the ignition switch off and restart initialization from procedure B.
