Checking components and wiring
Check that fuses 11D/7 and 11E/6 are intact.
Check the cable between fuse 11D/7 terminal #2 and relay 2/75 terminal #5. Check for an open-circuit according to Open-circuit, permanent faults . Check for a short-circuit to ground according to Short-circuit to ground, permanent faults .
Check the cable between relay 2/75 terminal #3 and the left and right head restraint solenoid connector terminal #1. Check for an open-circuit according to Open-circuit, permanent faults . Check for a short-circuit to ground according to Short-circuit to ground, permanent faults .
Check the cable between connector terminal #4 for each of the head restraints and the ground terminal for an open-circuit according to Open-circuit, permanent faults .
Remedy as necessary.
Check the resistance of each head restraint solenoid. Too high resistance indicates an open-circuit in the solenoid. Too low resistance indicates a short-circuit in the solenoid. Replace the head restraint in the event of a fault in the solenoid.
HINT: The resistance in a correct head restraint solenoid is 2.0 - 2.5 ohms. The resistance should be measured between connector terminals #1 and #4 on each of the head restraint solenoids.
