DTC 46

CIRCUIT DIAGRAM





INSPECTION PROCEDURE

FAILURE CONDITION:
DTC 46 can only be set during normal operation. If the Electronic Brake Control Module (EBCM) detects a condition in which it cannot move the motor in either direction, a malfunction exists.

DIAGNOSTIC AIDS:
An "intermittent" malfunction may be caused by a poor connection, rubbed through wire insulation or a wire that is broken inside the insulation.
The frequency of the malfunction can be checked by using the enhanced diagnostic function of the TECH-1, as described in "Enhanced Diagnostics". DTC 46 may set after modulator disassembly if the modulator pistons are positioned at the bottom of their bore.
Depending on the frequency of the malfunction, a physical inspection of the suspected mechanical parts may be necessary.
Any circuitry that is suspected of causing the intermittent malfunction should be thoroughly checked for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wiring connections or physical damage to the wiring harness.
