• When straightening body panels, use caution in pulling any HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.
• When cutting HSS panels, avoid gas (torch) cutting if possible. Instead, use a saw to avoid weakening surrounding areas due
to heat. If gas (torch) cutting is unavoidable, allow a minimum
margin of 50 mm (1.97in).
• When welding HSS panels, use spot welding whenever possi- ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.
• The spot weld on HSS panels is harder than that of an ordi- nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a low
speed high torque drill (1,000 to 1,200 rpm) to increase drill bit
durability and facilitate the operation.
• SP150 HSS panels with a tensile strength of 785 to 981 N/
mm
2 (80 to 100 kg/mm2 , 114 to 142 klb/sq in), used as rein-
forcement in the door guard beams, is too strong to repair.
When these HSS parts are damaged, the outer panels also
sustain substantial damage; therefore, the assembly parts
must be replaced.

1.CHECK SYMPTOM
Inspect engine cooling system.
Did the engine overheat?
YES >> • Repair cooling system. • Erase DTC and perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test". Then perform self-diagnosis of ICC system again.
NO >> • Replace ICC sensor and adjus t laser beam aiming. Refer to CCS-72, "
ICC Sensor".
• Erase DTC, then perform ICC system running test. Refer to CCS-8, "
ACTION TEST : ICC Sys-
tem Running Test". Then perform self-diagnosis of ICC system again.
