Component Testing
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
Liftgate Latch
- Ignition OFF, disconnect the harness connector at the M30 Liftgate Latch.
- Install a 10 A fused jumper wire between the control terminal 3 and 12 V. Install a jumper wire between the ground terminal 1 and ground.
- 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.
- If the M30 Liftgate Latch does not activate.
- All OK
Liftgate Release Switch
- Ignition OFF, disconnect the harness connector at the S46B Liftgate Unlatch Switch.
- Test for infinite resistance between the signal terminal 1 and the ground terminal 2 with the switch in the open position.
- If less than infinite resistance
Replace the S46B Liftgate Unlatch Switch.
- If infinite resistance
- If less than infinite resistance
- Test for less than 3 Ω between the signal terminal 1 and the ground terminal 2 with the switch in the closed position.
- If 3 Ω or greater
Replace the S46B Liftgate Unlatch Switch.
- If less than 3 Ω
- If 3 Ω or greater
- All OK
Relay Test
- Ignition OFF, disconnect the KR95A Liftgate Unlatch Relay.
- 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
- If less than 60 or greater than 200
- 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
- Install a 3 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
- 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
- If 2 Ω or greater
- All OK
