Code reading

Sudden motor stall on XH200 Opel Vectra prevented me from further driving few days ago. The way to know the reason is relatively easy on a ECU controled automobile, because the additional information system circuitry is embeded without using special diagnosis device, TECH2. By shortening #5 and #6 pins of OBD2(only coupler not actual OBD2) would show the defected parts with Morse signal. Though the signal explained that the cause was the crank angle sensor with the error code 0340, we cannot define the cause is the error on sensor itself, circuitry wiring or both. Careful checking yesterday proved the reason was the occasional openning and closing phenomena in the coupler connections. Several times removing and inserting couplers, recovered sure and firm connection again, remembering this coupler, no physical movement was applied for over 100,000km, rusting thin film on the pins and holders must have caused the error.

The diameter of the brake disc rotor may affect the steering reactions, also the weight has much to do with that of physical properties, increasing under sping weight, the 1st law of movement, Law of inertia and Gyroscopic phenomena.

They strongly affect on steering reaction and on compliance in axle construction.

Now I'm at a loss how to choose the frontal disk brake setting, 16' and 17' both disk rotors and brake calipers both are prepared. Yes 17' disk rotor has much weight comparing with that of 16', how shall I do about BC7 SUBARU Legacy LSi US model?

The setback value was precisely re-checked on NCP10 TOYOTA Vitz utilizing DIY special tool today obtaining repeatable datum within plus minus 300 micrometer. The suspicion I felt yesterday while high-way running was wiped away by this procedures.

Though this automobile is 9 years old with 50,000km running, I feel like new, after servicing by myself, the geometrical construction corrections by moving frontal main bur with twisting moment for setback adjustment, frontal camber correction into 38 minutes(angle value) negative cambers with precisions, rear right side negative camber 60 minutes that same as that of left side establishing zero thrust angle with 10 minutes total toe value. Brake fluid, automatic trans-axle fluid(TOYOTA genuine T4) are also replaced including Eg oil, without saying spark plugs that had not been replaced from the begining. Rear coil spring rubber seats for upper and lower were done additionally.

No wrong tendencies are not to be seen except unreliable steering reactions caused by deformable compliance bushes incorporated in frontal and rear lower arm hinge movement portions.
