Sprinter 3500 V6-3.0L DSL Turbo VIN 45 (2007)
When the shifter has been placed in "P," the transmission only allows 2nd gear operation. If this occurs while the vehicle is not moving, the transmission
only allows operation in 2nd gear.
Temporary Limp-In Mode
This mode is the same as the permanent Limp-In Mode except if the condition is no longer present, the system resumes normal operation.
Under Voltage Limp-In Mode
When the TCM detects that system voltage has dropped below 8.5 volts, it disables voltage-dependant diagnostics and places the transmission in the
temporary Limp-In Mode. When the TCM senses that the voltage has risen above 9.0 volts, normal transmission operation is resumed.
Hardware Error Mode
When the TCM detects a major internal error, the transmission is placed in the permanent Limp-In Mode and ceases all communication over the CAN
bus. When the TCM has entered this mode normal transmission operation does not resume until all DTCs are cleared from the TCM.
Loss of Drive
If the TCM detects a situation that has resulted or may result in a catastrophic engine or transmission problem, the transmission is placed in the neutral
position. Improper Ratio, Input Sensor Overspeed or Engine Overspeed DTCs cause the loss of drive.
Controlled Limp-in Mode
When a failure does not require the TCM to shut down the solenoid supply, but the failure is severe enough that the TCM places the transmission into a
predefined gear, there are several shift performance concerns. For instance, if the transmission is slipping, the controller tries to place the transmission
into 3rd gear and maintain 3rd gear for all forward drive conditions.
