Component Testing

WARNING: This page is about a different car, the 2020 GMC Terrain and 2020 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

Ignition/Vehicle - Off
Remove the component: Transmission Control Lever Knob
Disconnect the electrical connector: S3 Transmission Shift Lever
Test for 5, 900 to 6, 400 ohms between the test points: Signal terminal 3 & Ground circuit terminal 2
- If not between 5, 900 and 6, 400 ohms
  Replace the component: S2A Transmission Manual Shift Switch - Up/Down
- Go to next step: If between 5, 900 and 6, 400 ohms
Press and hold the switch: S2A Transmission Manual Shift Switch - Up/Down - Downshift
Test for 1, 900 to 2, 100 kohms between the test points: Signal terminal 3 & Ground circuit terminal 2
- If not between 1, 900 and 2, 100 ohms
  Replace the component: S2A Transmission Manual Shift Switch - Up/Down
- Go to next step: If between 1, 900 and 2, 100 ohms
Press and hold the switch: S2A Transmission Manual Shift Switch - Up/Down - Upshift
Test for 600 to 660 ohms between the test points: Signal terminal 3 & Ground circuit terminal 2
- If not between 600 and 660 ohms
  Replace the component: S2A Transmission Manual Shift Switch - Up/Down
- Go to next step: If not between 600 and 660 ohms
Test for infinite resistance between the test points: Each terminal of the component & The component's housing
- If less than infinite resistance
  Replace the component: S2A Transmission Manual Shift Switch - Up/Down
- Go to next step: If infinite resistance
All OK.
