Component Testing

Rear Compartment Lid Latch

1. Ignition OFF, disconnect the harness connector at the M30 Liftgate Latch.
2. Install a 25 A fused jumper wire between the control terminal 3 and 12 V. Install a jumper wire between the ground terminal 1 and ground.
3. Verify the M30 Liftgate Latch activates
   • If the M30 Liftgate Latch does not activate. 

     Replace the M30 Liftgate Latch.

   • If the M30 Liftgate Latch does activate. 
4. All OK

Liftgate Release Switch

1. Ignition OFF, disconnect the harness connector at the S58A Rear Compartment Lid Unlatch Switch-Exterior.
2. Test for infinite resistance between the signal terminal 2 and the ground terminal 1 with the switch in the open position.
   • If less than infinite resistance 

     Replace the S58A Rear Compartment Lid Unlatch Switch-Exterior.

   • If infinite resistance 
3. Test for less than 3 Ω between the signal terminal 2 and the ground terminal 1 with the switch in the closed position.
   • If 3 Ω or greater 

     Replace the S58A Rear Compartment Lid Unlatch Switch-Exterior.

   • If less than 3 Ω 
4. All OK

Relay Test

1. Ignition OFF, disconnect the KR95A Liftgate Unlatch Relay.
2. Test for 60-200 Ω between terminals 85 and 86.
   • If less than 60 or greater than 200 

     Replace the KR95A Liftgate Unlatch Relay.

   • If between 60-200 Ω 
3. Test for infinite resistance between the terminals listed below:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If less than infinite resistance 

     Replace the KR95A Liftgate Unlatch Relay.

   • If infinite resistance 
4. Install a 3 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
5. Test for less than 2 Ω between terminals 30 and 87.
   • If 2 Ω or greater 

     Replace the KR95A Liftgate Unlatch Relay.

   • If less than 2 Ω 
6. All OK
