AD32.32-P-3000A | Adaptive damping system (ADS II) diagnosis, function check | 24.2.97 |
MODEL 129 as of 1.9.95
| Note on function check of adaptive damping system (ADS II) | ||
Test step/scope of test | Operation/requirement | Specified value | Possible cause/remedy |
1 ADS MIL (A1e27) | Ignition: ON Level adjustment switch (S77/1) in position: Normal level Engine: Idling |
A1e27: ON A1e27: OFF | Read out fault memory and actual values with HHT. Steering angle sensor not initialized: Turn steering wheel from stop to stop. Fault stored: Read out fault memory and actual values with HHT. |
2 Comfort/sport switch ADS (S45/1) | Position: Sport Position: Comfort | LED in switch: ON LED in switch: OFF | Read out fault memory and actual values with HHT. Read out fault memory and actual values with HHT. |
3 High/normal level control switch S77/1s2 Raise level Raise level Hold level | Engine: Idling S77/1s2 in position: Normal level S77/1s2 in position: High level stage 1 (press once) S77/1s2 in position: Normal level S77/1s2 in position: High level stage 2 (press twice) Ignition: OFF Wait 1 minute | ADS MIL (A1e27): OFF LEDs in switch: OFF 1 LED in switch: Flashes Vehicle is raised up to 35 mm. LED illuminates continuously once the level is reached. Note: The process proceeds slowly. Possibly accelerate the process at a slightly higher engine speed (approx. 2000 rpm). Vehicle lowers. LEDs in switch: OFF 2 LEDs in switch: Flash Vehicle is raised up to 60 mm. Both LEDs illuminate continuously once the level is reached. Note: The process proceeds slowly. Possibly accelerate the process at a slightly higher engine speed (approx. 2000 rpm). Vehicle remains at higher level | Read out fault memory and actual values with HHT |
4 Level control lock-out switch S77/1s1 | Ignition: ON Press S77/1s1 Engine: Idling | LEDs in high/normal level control switch S77/1s2: ON Lamp in S77/1s1: ON LEDs in high/normal level control switch S77/1s2: OFF Lamp in S77/1s1: ON LED's in high/normal level control switch S77/1s2: OFF ADS MIL (Ale27): ON | Read out fault memory and actual values with HHT |
