Measure
Try to reproduce the customer complaint so that it can be clearly assigned to this TPI.
The following repair must only be carried out, if all the criteria (model/type, chassis number, engine/gearbox code,
PR number(s), software version, code etc. ) match exactly. Otherwise this solution won't work and repeat repairs may be necessary. In such a case, we may reject the warranty claim and redebit the parts.
1. Check the fuse SB-2 (30A.) for the Mechatronics power supply (J743) according to the current flow diagram. If the fuse is incorrect, replace it.
2. Check the system again. If the complaint is fixed, replace the Mechatronics according to the repair manual.
