Component Testing

Liftgate Unlatch Switch

1. Vehicle OFF, disconnect the harness connector at the S46B Liftgate Unlatch Switch.
2. Test for infinite resistance between the signal terminal 2 and the ground terminal 4 with the switch in the open position.
   • If less than infinite resistance 

     Replace the S46B Liftgate Unlatch Switch.

   • If infinite resistance 
3. Test for infinite resistance between the signal terminal 3 and the ground terminal 4 with the switch in the open position.
   • If less than infinite resistance 

     Replace the S46B Liftgate Unlatch Switch.

   • If infinite resistance 
4. Test for less than 2 Ω between the signal terminal 2 and the ground terminal 4 with the switch in the Lock position.
   • If 2 Ω or greater 

     Replace the S46B Liftgate Unlatch Switch.

   • If less than 2 Ω 
5. Test for less than 2 Ω between the signal terminal 3 and the ground terminal 4 with the switch in the Unlock position.
   • If 2 Ω or greater 

     Replace the S46B Liftgate Unlatch Switch.

   • If less than 2 Ω 
6. All OK

Liftgate Lock Actuator

1. Vehicle OFF, disconnect the harness connector at the M14B Door Lock Actuator-Liftgate.
2. Install a 25 A fused jumper wire between one of the control terminals and 12 V. Momentarily install a jumper wire between the other control terminal and ground. Reverse the jumper wires at least two times, the M14B Door Lock Actuator-Liftgate should perform the LOCK and UNLOCK function.
   • If the actuator does not perform the LOCK and UNLOCK function 

     Replace the M14B Door Lock Actuator-Liftgate.

   • If the actuator performs the LOCK and UNLOCK function 
3. All OK
