D1 CHECK THE MOTOR SUPPLY CIRCUITS
Disconnect: Horizontal Motor C362.
NOTE: Make sure all connectors are connected on the seat.
Measure the resistance between horizontal motor C362, Circuit 981
(RD/WH), harness side and ground; and between horizontal motor
C362, Circuit 980 (YE/WH), harness side and ground.
Are the resistances less than 5 ohms?
D2 CHECK CIRCUIT 981 (RD/WH) AND 980 (YE/WH) FOR AN OPEN
Disconnect: Seat Regulator Control Switch C360.
Measure the resistance between horizontal motor C362, Circuit 981
(RD/WH), harness side and seat regulator control switch C360-3,
Circuit 981 (RD/WH), harness side; then between horizontal motor
C362, Circuit 980 (YE/WH), harness side and seat regulator control
switch C360-8, Circuit 980 (YE/WH), harness side.
Is the resistance less than 5 ohms?
D3 CHECK CIRCUIT 981 (RD/WH) AND 980 (YE/WH) FOR A SHORT
TO GROUND
Measure the resistance between horizontal motor C362, Circuit 981
(RD/WH), harness side and ground; and between horizontal motor
C362, Circuit 980 (YE/WH), harness side and ground.
Are the resistances greater than 10,000 ohms?
