Component Testing

Rear Compartment Lid Latch

1. Ignition OFF, disconnect the harness connector at the M40 Rear Compartment Lid Latch.
2. Install a 10 A fused jumper wire between the B+ terminal 1 and 12 V. Install a jumper wire between the ground terminal 2 and ground.
3. Verify the M40 Rear Compartment Lid Latch activates
   • If the M40 Rear Compartment Lid Latch does not activate. 

     Replace the M40 Rear Compartment Lid Latch.

   • If the M40 Rear Compartment Lid Latch does activate. 
4. All OK

Trunk Release Switch

1. Ignition OFF, disconnect the X920 inline harness connector at the S58A Rear Compartment Lid Unlatch Switch-Exterior.
2. Test for infinite resistance between the signal circuit terminal 4 and the ground circuit terminal 3 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 circuit terminal 4 and the ground circuit terminal 3 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 KR95B Rear Compartment Lid Unlatch Relay.
2. Test for 60-200 Ω between terminals 1 and 3.
   • If less than 60 Ω or greater than 200 Ω 

     Replace the KR95B Rear Compartment Lid Unlatch Relay.

   • If between 60-200 Ω 
3. Test for infinite resistance between the terminals listed below:
   • 4 and 3
   • 4 and 5
   • 4 and 1
   • 5 and 1
   • If less than infinite resistance 

     Replace the KR95B Rear Compartment Lid Unlatch Relay.

   • If infinite resistance 
4. Install a 3 A fused jumper wire between relay terminal 3 and 12 V. Install a jumper wire between relay terminal 1 and ground.
5. Test for less than 2 Ω between terminals 4 and 5.
   • If 2 Ω or greater 

     Replace the KR95B Rear Compartment Lid Unlatch Relay.

   • If less than 2 Ω 
6. All OK
