Complaint:
Engine does not start, or various fault messages in instrument cluster immediately after engine start and servo assistance is reduced.
The following display messages may appear:
- Red message "Power Steering Malfunction - See Operator's Manual" including acoustic warning
- Red or yellow message "ESP / ABS Currently Unavailable - See Owner's Manual", sometimes with acoustic warning
- White message about tire pressure monitor or run flat indicator: "Tire Pressure Loss Warning Defective" or "Tire
Pressure Monitor Defective"
In addition, the indicator lamps of the following systems may light up:
- Brakes / ABS / ESP / ESP Off / engine diagnosis
Furthermore:
- The chassis CAN is partially or completely disrupted
- Several control units (e.g. the electric power steering, ESP, engine etc.) cannot be interrogated or are not listed in
the quick test
- Various CAN communication errors from other control units may be logged (see list "Control unit / Fault code")
Cause:
Software of electric power steering.
Remedy:
The following procedure must be followed:
1.) Unplug power supply connector to steering, wait 5 seconds and reconnect
Note: Observe WIS document AH54.00-P-0001-01A
2.) Perform software update of electric power steering (ES) control unit via "Adaptations"
