THEORY OF OPERATION
The Driver Active Headrest signal circuit is driven by a solenoid that also uses a diode in parallel. The
single electrical component of the AHR (Active Headrest) unit is the latch-release solenoid. The solenoid
is connected by a 2 way pigtail wire and harness connector. The pigtail wire and 2 way connector are
routed through the center of one of the headrest support posts and down through the guide sleeve to the
interior of the seat back, where it connects to the seat wire harness. The solenoid is grounded at an
independent dedicated ground. The AHR components itself cannot be repaired. If damaged or
ineffective, the AHR (Active Headrest) must be replaced as a new assembly. If upon inspection the AHR
has deployed it can be reset following the proper reset method. Refer to RESTRAINT, ACTIVE HEAD,
STANDARD PROCEDURE . Also if the already deployed Driver or Passenger AHR are latched in the
locked position please see the scan tool miscellaneous functions to set the latch in the unlock or
deployed position. Please be very observant and careful, the scan tool should never be used to actually
deploy a known good non-deployed Driver or Passenger AHR.
WHEN MONITORED
The Occupant Restraint Controller (ORC) continuously communicates with the Driver Active Headrest
over the Active Head Restraint 1st Row Driver Signal circuits. The Driver Active Headrest
communication and on board diagnostics are powered by the ORC signal.
SET CONDITION
This code will set, if the ORC detects High voltage on the (R676) Active Head Restraint 1st Row Driver
Signal circuit.
POSSIBLE CAUSES
Possible Causes
