Diagnostic Trouble Code (DTC) Memory [12]
Preparation for DTC Readout
Warning Life threatening injures possible due to vehicle slipping or toppling off while on lift.
Prior to lift vehicle completely (wheels still in contact with floor), ensure that the vehicle is centered within the lift columns and lift arm supports are correctly placed unto the vehicle contact points.
Control Module Adaption:
After the swap of the ESP/SPS/BAS or ESP/BAS control module (N47-5), it is important to perform the adaption procedure, since the control module must learn the values for the steering ratio. See HHT menu.
Additionally, after replacing either the ESP/SPS control module (N47-5) or the brake booster (A7/7), it is absolutely necessary to perform an adaption of the ESP/SPS control module (N47-5) as well.
The ESP/SPS control module (N47-5) has to learn the values for the BAS solenoid valve (A7/7y1), see HHT menu.
1. Review: [11], [21], [22], [23] (connector connections).
2. Connect Hand-Held Tester (HHT) to data link connector (X11/4) according to connection diagram (see section 0) and read out DTC memory.
3. Ignition: ON
Note: The BAS control module is integrated into the ESP control module.
Read out DTC memory for the BAS, ETS, ME and ETC systems.
Note The replacement or swap of the ABS Lateral Acceleration sensor (B43) and/or the Rotating Speed Sensor for ESP (B45), requires that a driving test is to be performed, see 11
