Component Testing

Seat Adjuster Switch Test

1. Ignition OFF, disconnect the X1 and X2 harness connectors at the S64P Seat Adjuster Switch - Passenger.
2. Test for infinite resistance between the B+ terminal 10 X1 and each control terminal with the switch in the open position.
   • If less than infinite resistance 

     Replace the S64P Seat Adjuster Switch - Passenger.

   • If infinite resistance 
3. Test for less than 2 Ω between the B+ terminal 10 X1 and each control terminal with the appropriate switch in the closed position.
   • If 2 Ω or greater 

     Replace the S64P Seat Adjuster Switch - Passenger.

   • If less than 2 Ω 
4. Test for less than 2 Ω between the ground terminal 5 X1 and each control terminal with the switch in the open position.
   • If 2 Ω or greater 

     Replace the S64P Seat Adjuster Switch - Passenger.

   • If less than 2 Ω 
5. All OK.

Seat Motor

1. Ignition OFF, disconnect the harness connector at the appropriate seat motor listed below:
   • M51P Passenger Seat Horizontal Motor - Passenger
   • M57P Passenger Seat Vertical Motor - Passenger
   • M56P Passenger Seat Recline Motor - Passenger
NOTE:

When performing the following tests, make sure that the seat is not already in the position the test is attempting to produce.

2. Install a 30 A fused jumper wire between control terminal 1 and 12 V.
3. Momentarily install a jumper wire between control terminal 3 and ground. The seat motor should momentarily perform the appropriate FORWARD/ REARWARD/ UP/ DOWN function.
   • If the motor does not perform the FORWARD/ REARWARD/ UP/ DOWN function 

     Replace the motor.

   • If the motor performs the FORWARD/ REARWARD/ UP/ DOWN function 
4. Reverse the jumper wires; the motor should perform FORWARD/ REARWARD/ UP/ DOWN function.
   • If the motor does not perform the FORWARD/ REARWARD/ UP/ DOWN function 

     Replace the motor.

   • If the motor performs the FORWARD/ REARWARD/ UP/ DOWN function 
5. All OK.
