The fault may then go inactive after the unit warms up. An active fault in cold conditions can also go inactive after the unit sits in a warm shop. Solution If the fault is always active regardless of conditions or is intermittent in warm weather then there is a real failure of a component. Follow Guided Diagnostics ( GD ) in this situation. The fault will have to be ACTIVE during fault tracing to find the issue and the unit may have to be operated in the conditions that trigger the fault. Symptoms of this fault are: 1. Check for transmission messages on the Instrument Cluster ( IC ) 2. Check lamp illuminated 3. Reduced clutch performance 4. Reduced gearbox comfort at start 5. Gear changes are slow Conditions that activate this fault are: 1. Open circuit on any of the sensor signals is detected when one of the sensor signals is within normal range and the other sensor signal is below normal range 2. Open circuit on ground, detected when both the sensor signals are within the normal range and the sum of the sensor signals is above a specific value If the unit drives normally and the fault lamp goes out after the unit warms up then it is unlikely replacing a component will fix the issue. If the chassis is equipped with an AMT-F, updated software is available to correct a fault detection setting that made the condition worse. If the fault is active, update the AMT-F gearbox to the latest software, then recreate the conditions that triggered the fault. This may include letting the unit sit outside overnight in cold weather and rechecking for the fault. If the software does not improve the condition, replace the Clutch Position Sensor. There is not currently a software solution for the AMT-D gearboxes. Active faults should be addressed by replacing the Clutch Position Sensor. Internal comments (BO) This is a known fault and is under investigation. Recent data shows that the faults listed here are showing up at an increased rate. The fault frequency data from Telematics Gateway ( TGW ) shows this to be a cold weather related fault with virtually no faults occurring in the hotter months of the year. The supplier of the position sensor has identified a possible root cause for this fault and is in the process of verifing. The supplier of the sensor has identified a root cause with the sensor and is currently working on a solution. For the short term, updating SW is still the best option. A more agressive SW solution is being considered to bridge the gap between current conditions and the release of the new sensor. Even with replacement of the sensor the fault may still return.
