Inspection With GDS

Initialization and diagnosis sequence by using GDS equipment.

Below content summarize the procedure for A/S using GDS.

No.Procedure
1Locate vehicle to flat plane
2Tire check
3IGN1 ON
4Head lamp Low Beam ON
5Connection with diagnostic tool
6Initial command by diagnostic tool
7Clear DTC Code
8IGN1 OFF --> ON
9Re-Connection with diagnostic tool
10Checking of HLLD output value as 15% and DTC Code
11HLLD actuating by diagnostic tool command
12Head lamp mechanical Initial Aiming

REPAIR PROCEDURES CHART

Note. There's no loads in vehicle and vehicle should be on flat plane. Should check of HLLD output value after initial setting. Should do first electrical initial setting by diagnostic tool and then mechanical aiming afterward.

Inspection

  1. Ignition "ON".
  2. Turn on the head lamp switch.
  3. Check for operation. If the aim of the head lamps changes smoothly when the head lamp leveling switch is turned.
  4. If the operation does not work well, inspect the connector and terminals to be sure they are all making good contact. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to step 5.
  5. Substitute with a known-good head lamp assembly and check for proper operation.
