Circuit Description
DTC C1348 detects a stripped nut or stripped gear assembly during initialization. During the homing sequence the piston should reach the bottom of the bore. When the piston reaches the bottom of the bore the TCS motor stalls. If the TCS motor does not stall, then the TCS motor spins with little or no resistance. If the TCS motor spins with little or no resistance then a nut/screw malfunction exists.

Conditions For Setting The DTC
DTC C1348 will only set during initialization.
A malfunction exists if the feedback current is less than the command current for a specified period of time.

Action Taken When The DTC Sets
^ A malfunction DTC stores.
^ The TCS disables.
^ The amber TCS indicator turns on.
^ The red BRAKE warning indicator turns on.

Conditions for Clearing The DTC
^ The condition responsible for setting the DTC no longer exists and the Scan Tool Clear DTC function is used.
^ 100 drive cycles pass with no DTC detected.

Diagnostic Aids
An intermittent malfunction in DTC C1348 may be caused by one of the following conditions in a mechanical part of the system:
^ Sticking
^ Binding
^ Slipping
Depending on the frequency of the malfunction, physical inspection of the mechanical parts suspected of causing the malfunction may be necessary. Use the enhanced diagnostic function of the Scan Tool in order to measure the frequency of the malfunction. Refer to the Scan Tool manual or Scan Tool Diagnostics for the procedure. If the DTC only occurs once and DTC C1361 also occurs, refer to DTC C1361 Right TCS Motor Circuit Open. If the DTC is intermittent and enhanced diagnostics show this DTC occurs during TCS, refer to DTC C1361 Right TCS Motor Circuit Open.

Important: Zero the J39200 test leads before making any resistance measurements.
