(Auto Pilot System (APS) Diagnosis Troubleshooting - AD82.61-P-5000C)
MODEL 463 up to 30.6.99 with CODE (ET6) Auto pilot system (APS)
| To prevent damage to the control modules, couplings must only be disconnected or connected with "terminal 15R: OFF ". | |||
| When pushing in the radio and navigation operating unit (APS) (A2/29) do not press on the rotary transducers as these may become damaged. Use the frame of the display (left and right) as the pressure point when pushing the unit in. | Remove and reinstall the radio and navigation operating unit, APS | AR82.61-P-7412G | |
| 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 | AD82.60-P-2000-07C | |
| AD82.61-P-6000-01C | |||
| No communication possible between Hand-Held Tester (HHT) and auto pilot system | Cables, radio and navigation operating unit (APS) (A2/29) | AD82.61-P-6000-04C | |
| Navigation inoperative | Navigation CD-ROM is not inserted or is inserted incorrectly or incorrect CD-ROM | Insert navigation CD, refer to: GF82.61-P-0001-03J | |
| Fuse in APS navigation processor (A2/30) | AD82.61-P-2000-02C | ||
| AD82.61-P-6000-02C | |||
| Voltage supply for A2/30 | AD82.61-P-4000C | ||
| CAN data bus | Read out fault memory with HHT |
AD82.61-P-6000-05C | |
| Navigation is defective | Navigation CD not is not inserted or is inserted incorrectly or incorrect CD-ROM | Insert navigation CD, refer to: GF82.61-P-0001-03J | |
| Check variant coding and wheel calibration | AD82.61-P-4000C | ||
| Global positioning system (GPS) APS navigation processor (A2/30) | Read out fault memory with HHT | AD82.61-P-6000-06C | |
| AD42.30-P-1000BZ | |||
| Reverse gear signal | Read out actual value with HHT | ||
| Wheel sensors | Read out actual values with HHT | ||
| Route guidance instructions are output too early or too late (e.g. "Please turn right") | Check wheel calibration | GF82.61-P-0001-03J | |
| Audio response is fragmentary or inoperative | Language in RAM of APS navigation processor (A2/30) partly erased due to voltage open-circuit | Test HHT menu item "Actuations, audio response" | Reload language, refer to: GF82.61-P-0001-03J |
| AD82.61-P-6000-03C | |||
| Cables, radio and navigation operating unit (APS) (A2/29), APS navigation processor (A2/30) | Avoid severe vibrations at A2/30 when loading the language. |
||
| Display readout is difficult to read | Display contrast too slight | Adjust display contrast: GF82.61-P-0001-03J |
