| Battery voltage 11-14 V | ||
| The APS system must be calibrated to the tires fitted. | ||
Troubleshooting | |||
Complaint | Cause | Note | Remedy |
Radio and navigation operating unit (APS) (A2/29) completely inoperative | Fuse in A2/29 Voltage supply for A2/29 | ||
No communication between Hand-Held Tester (HHT) and auto pilot system possible | K cable, Radio and navigation operating unit (APS) (A2/29) | Models 129, 140, 202, 208 and 210 Model 168 | |
Navigation inoperative | Navigation CD-ROM not inserted or incorrectly inserted or incorrect CD-ROM Fuse in navigation processor (A2/30) Voltage supply for A2/30 CAN APS data bus | CD-ROM is not upwards compatible Read out fault memory with HHT | Insert navigation CD, refer to: |
Navigation is faulty | Navigation CD not inserted or incorrectly inserted or incorrect CD-ROM Check variant coding and wheel calibration Navigation processor (A2/30) global positioning system (GPS) Reverse gear signal Vehicle speed signal | CD-ROM is not upward compatible Read out fault memory with HHT Read out actual value with HHT | Insert navigation CD, refer to: |
Dynamic navigation with TMC inoperative, radio UKW reception is, however, possible Code 815 only | Traffic data recorder (A2/43) Radio and navigation operating unit (APS) (A2/29) or CAN connection between A2/29 and A2/43 Navigation processor (A2/30) or CAN connection between A2/30 and A2/43 | Test variant coding with Hand-Held Tester (TELEMATIK: YES) Test dynamic navigation with TCS (refer to Owner’s Manual). | |
Dynamic navigation with TCS inoperative Code 815 only, not code 348 (TELE AID) | SIM card is not configured for dynamic navigation CTEL interface (A34/4) Traffic data recorder (A2/43) or CAN connection between A34/4 and A2/43 Navigation processor (A2/30) or CAN connection between A2/30 and A2/43 Radio and navigation operating unit (APS) (A2/29) | Test variant coding with Hand-Held Tester (TELEMATIK: YES) Test dynamic navigation with TMC (refer to owner’s manual). | Configure SIM card, refer to |
Messages from navigation are given too early or too late (e.g."Please turn to the right") | Check wheel calibration | ||
Voice output is fragmented or inoperative | Language in RAM of navigation processor (A2/30) is partly deleted as a result of interruption in voltage Cables, radio and navigation operating unit (APS) (A2/29), navigation processor (A2/30) | Test HHT menu item"Voice output actuation" Avoid violent shaking of A2/30 during language loading | To re-load language, refer to: |
Radio or loudspeaker function disruptions, loud noise with voice output | Refer to DHB information / communication register 3 and DHB information / communication register 5 | ||
Display is difficult to read | Display contrast too weak | Adjust display contrast: |
