Component Testing

Liftgate Window Unlatch Switch

Ignition OFF, disconnect the harness connector at the S141 Liftgate Window Unlatch Switch.
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 S141 Liftgate Window Unlatch Switch.
- Go to next step: If infinite resistance
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 S141 Liftgate Window Unlatch Switch.
- Go to next step: If less than 3 Ω
All OK

Liftgate Window Latch

Ignition OFF, disconnect the harness connector at the M33 Liftgate Window Latch Assembly.
Install a 10 A fused jumper wire between the control terminal 1 and 12 V. Install a jumper wire between the ground terminal 2 and ground.
Verify the M33 Liftgate Window Latch Assembly activates
- If the M33 Liftgate Window Latch Assembly does not activate.
  Replace the M33 Liftgate Window Latch Assembly.
- Go to next step: If the M33 Liftgate Window Latch Assembly does activate.
All OK

Relay Test

Ignition OFF, disconnect the KR162 Liftgate Window Unlatch Relay.
Test for 60-180 Ω between terminals 86 and 85.
- If less than 60 Ω or greater than 180 Ω
  Replace the KR162 Liftgate Window Unlatch Relay.
- Go to next step: If between 60-180 Ω
Test for infinite resistance between the terminals listed below:
- 86 and 30
- 86 and 87
- 85 and 30
- 85 and 87
- If less than infinite resistance
  Replace the KR162 Liftgate Window Unlatch Relay.
- Go to next step: If infinite resistance
Install a 3 A fused jumper wire between relay terminal 86 and 12 V. Install a jumper wire between relay terminal 85 and ground.
Test for less than 2 Ω between terminals 30 and 87.
- If 2 Ω or greater
  Replace the KR162 Liftgate Window Unlatch Relay.
- Go to next step: If less than 2 Ω
All OK
