| The discrete wires are diagnosed by the convenience system central control unit -J393- and the onboard supply control unit -J519-, and can be checked in „Guided Fault Finding“ using the following functional checks: |
| Select „46 - Convenience system central module | J393 “„05 - Electrical components (=> in -J393)“„J764 - ESL control unit (Rep.Gr.48)“: |
| t
| „J764 - ESL, enabling steering column lock (Rep.Gr.48)“ for discrete „ESL enable“ wire from convenience system central control unit -J393- to electronic steering lock control unit -J764-. |
| t
| „J764 - ESL, enabling terminal 15 (Rep.Gr.48)“ for discrete „terminal 15 enable“ wire from electronic steering lock control unit -J764- to convenience system central control unit -J393-. |
| Select „09 - Electronic central electrics | J519 “„09 - Subsystems conditions“ : |
| t
| „J519 - onboard power supply control unit, enabling steering column lock“ for discrete „ESL enable“ wire from onboard supply control unit -J519- to electronic steering lock control unit -J764-. |
Note | t
| After renewing the steering column, the function „16 - Calibrate steering angle sender -G85- (Rep. Gr. 94)“ must be performed; the electronic steering column lock control unit -J764- can be left installed in the vehicle and does not have to be re-adapted. |
