DTC 47

CIRCUIT DIAGRAM











INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
These DTCs are designed to detect a stripped nut or gear assembly during initialization. During the homing sequence, the piston should reach the top of the bore resulting in a stalled motor. If this does not occur, the motor must be spinning with little or no resistance. This indicates a nut/screw or gear malfunction.

FAILURE CONDITION:
DTCs 47 and 48 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.

DIAGNOSTIC AIDS:
An "intermittent" malfunction of this DTC may tee caused bye sticking, binding or slipping mechanical part of the system.
The frequency of the malfunction can be checked by using the enhanced diagnostic function of the TECH-1 as described in "TECH-1 Diagnostics. If the DTC only fails once and DTC 56 or 61 also fails. If intermittent and enhanced diagnostics show this DTC fails during Antilock Brake System (ABS) operation, refer to DTC 56 or 61.
Depending on the frequency of the malfunction, a physical inspection of the suspected mechanical parts may be necessary.
