TEST RESULTS
1CHECK TYRE WEARALL OKPROBLEMS ENCOUNTEREDACTION
Check the tyre wear status.Specifically:- wear on outer edge;- wear on inner edge;- wear on tyre shoulder;- tread wearMove on to Step 41. Uniform wear on both sides: inflation pressure low2. Step wear on one side (outer or inner)3. Wear on outer edge: exterior smooth4. Tyre shoulder wear5. Central tread wear: inflation pressure excessive6. Uniform wear on tread surface: compound quality7. Tread wear.1. Make sure tyres are inflated to the correct pressure. If necessary, replace the tyres.2. Move on to Step 23. Move on to Step 24. The problem is due to the customer''s over-sporty driving style: If necessary, replace the tyres.5. Make sure tyres are inflated to the correct pressure. If necessary, replace the tyres.6. Replace the tyres.7. Replace the tyres.
2CHECK FRONT WHEEL GEOMETRYALL OKPROBLEMS ENCOUNTEREDACTION
Check the front wheel geometryMove on to Step 3Front wheel geometry not correctRestore correct geometry    Op. 4450A10 FRONT WHEEL GEOMETRY - CHECK USING OPTICAL EQUIPMENT - INCLUDES ADJUSTMENT IF NECESSARY if necessary, replace the front tyres.
3REAR WHEEL GEOMETRYALL OKPROBLEMS ENCOUNTEREDACTION
Check the rear wheel geometryMove on to Step 4Rear wheel geometry not correctRestore correct geometry    Op. 4450A40 REAR WHEEL GEOMETRY - CHECK USING OPTICAL EQUIPMENT, INCLUDES ADJUSTMENT IF NECESSARY if necessary, replace the rear tyres.
4SHOCK ABSORBER EFFICIENCY CHECKALL OKPROBLEMS ENCOUNTEREDACTION
Check the efficiency of the shock absorbers.End of diagnosis1. Front shock absorbers inefficient.2. Rear shock absorbers inefficient.1. Replace the front shock absorbers.    Op. 4410A12 FRONT SUSPENSION DAMPER (ONE), LH OR RH - FOR MCPHERSON STRUT SYSTEM - INCLUDES DISMANTLING/REASSEMBLY OF ASSEMBLY AT BENCH - R.R If necessary, replace the front tyres.2. Replace the rear shock absorbers.    Op. 4420A30 REAR SUSPENSION SHOCK ABSORBER (ONE), LEFT OR RIGHT - R.R. - CHECK WHEEL GEOMETRY SEPARATELY If necessary, replace the rear tyres.
