Component Testing

A23C Liftgate Latch Assembly-Dynamic Test

1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: A23C Liftgate Latch Assembly
3. Connect a jumper wire between the test points: Ground terminal 1 & Ground
4. Momentarily connect a 7.5 A fused jumper wire between the test points: Control terminal 3 & 12 V

   Verify the component turns On and Off when connecting and disconnecting the jumper wire: A23C Liftgate Latch Assembly

   • If the component does not turn On and Off 

     Replace the component: A23C Liftgate Latch Assembly

   • Go to next step: If the component turns On and Off 
5. All OK.

S46 Liftgate Handle Switch

1. Ignition/Vehicle - Off
2. Disconnect the electrical connector: S46 Liftgate Handle Switch
3. Test for infinite resistance between the test points: Signal terminal 1 & Ground terminal 2 - Not Pressed
   • If less than infinite resistance 

     Replace the component: S46 Liftgate Handle Switch

   • Go to next step: If infinite resistance 
4. Test for less than 3 ohms between the test points: Signal terminal 1 & Ground terminal 2 - Pressed
   • If 3 ohms or greater 

     Replace the component: S46 Liftgate Handle Switch

   • Go to next step: If less than 3 ohms 

Relay Test

1. Ignition/Vehicle - Off
2. Remove the component: KR95A Liftgate Unlatch Relay
3. Test for 70 to 110 ohms between the test points: Component terminal 85 & 86
   • If not between 70 and 110 ohms 

     Replace the component: KR95A Liftgate Unlatch Relay

   • Go to next step: If between 70 and 110 ohms 
4. Test for infinite resistance between the test points:
   • Component terminal 30 & 85
   • Component terminal 30 & 86
   • Component terminal 30 & 87
   • Component terminal 85 & 87
   • If less than infinite resistance 

     Replace the component: KR95A Liftgate Unlatch Relay

   • Go to next step: If infinite resistance 
5. Connect a 3 A fused jumper wire between the test points: Component terminal 86 & 12 V

   Connect a jumper wire between the test points: Component terminal 85 & Ground

6. Test for less than 2 ohms between the test points: Component terminal 30 & 87
   • If 2 ohms or greater 

     Replace the component: KR95A Liftgate Unlatch Relay

   • Go to next step: If less than 2 ohms 
7. All OK.
