Circuit Description
This DTC is designed to detect a stripped nut or gear assembly during initialization. During the homing sequence, the piston should reach the bottom of the bore resulting in a stalled Traction Control System (TCS) motor. If this does not occur, the TCS motor must be spinning with little or no resistance, indicating a nut/screw or gear malfunction.


Conditions for Setting the DTC
DTC C1348 can only be set during initialization. If the feedback current is less than the command current for a specified period of time, a malfunction exists.


Action Taken When the DTC Sets
A malfunction DTC is stored, TCS is disabled, and the amber TCS warning indicator and the red BRAKE warning indicator are turned on.

Conditions for Clearing DTC
Condition for DTC is no longer present and the scan tool (CLEAR DTCs) function is used, or 100 drive cycles have passed with no DTCs detected.


Diagnostic Aids
An intermittent malfunction in this DTC may result from a mechanical part of the system that sticks, binds, or slips.

The frequency of the malfunction can be checked by using the enhanced diagnostic function of the scan tool, as described in the Scan Tool manual. If the DTC only occurs once and DTC C1361 also occurs, refer to DTC C1361. If intermittent and enhanced diagnostics shows this DTC occurs during TCS, refer to DTC C1361.

Depending on the frequency of the malfunction, a physical inspection of the mechanical parts suspected of causing the malfunction may be necessary.
