WARNING: This page is about a different car, the 2019 Chevrolet Traverse. However, it is still accessible from the selected car via links, so may be relevant.

Ignition OFF, measure and record the C1 Battery voltage at the terminals.
Verify the measured voltage is between 12.0 - 15.0 V.
- If voltage is less than 12.0 V or greater than 15.0 V
  Refer to Battery Inspection/Test .
- Go to next step: If voltage is between 12.0 - 15.0 V
Test for less than 0.5 V between the positive battery terminal and positive terminal at the X50D Fuse Block - Battery with the ignition in the CRANK/START position.
- If 0.5 V or greater
  Replace the positive battery cable.
- Go to next step: If less than 0.5 V
Test for less than 0.5 V between the positive battery cable at the X50D Fuse Block - Battery and terminal 1 X2 or A X2 at the M64 Starter Motor with the ignition in the CRANK/START position.
- If 0.5 V or greater
  Replace the positive battery cable.
- Go to next step: If less than 0.5 V
Test for less than 0.5 V between the negative battery cable and the M64 Starter Motor case with the ignition in the CRANK/START position.
- If 0.5 V or greater
  Replace the negative battery cable.
- Go to next step: If less than 0.5 V
Perform Battery Inspection/Test Using the EL-50313 Midtronics Battery Tester/Charger.
- If Battery Fails the Test
  Replace the C1 battery.
- Go to next step: If the Battery Passes the Test
  Go to next step: Replace the M64 Starter Motor.
