Component Testing: TCSCS
WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
- Using the L-BU probes J 35616-65B, connect the memory saver harness, EL49741, to the TCSCS as specified below for the LED being tested. Connecting the harness in the opposite pins will not illuminate the LED.
- Connect a 9 V battery to the memory saver harness EL49741.
- Verify that only the indicator being tested illuminates.
- If the indicator does not illuminate when tested or the incorrect indicator illuminates, replace the TCSCS.
