Warning:
For Scania vehicles with a steered tag axle: When working on the ESTA system, tag axle or when lifting the vehicle with vehicle lifts, the steered tag axle must be set in the maintenance position using SDP3. This is to prevent steering of the tag axle wheels.
When the starter key is turned to the drive position, ESTA carries out a functional check which turns the tag axle wheels slightly. This steering of the tag axle wheels can result in personal injury during workshop operations in the vicinity of the tag axle wheels and the vehicle can affect the vehicle lifts.
Procedures:
1.Remove the screws and connector and renew the control unit. The control unit is fitted with 4 screws and has 2 connectors.
2.Spare parts program the control unit using SDP3.
Information!
In spare parts programming, the calibrated values of the tag axle and the adjusted rolling direction are stored. No adjustment of the tag axle rolling direction needs to be carried out after renewing the control unit.
