Diagnostic Aids
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- A dead battery is usually a symptom of another problem. Fix the problem, do not just charge or change the battery.
- Failure to properly understand the battery and its function could lead to a misdiagnosis and unneeded repairs. Refer to Battery Description and Operation and Battery Common Causes of Malfunction for more information.
Follow these instructions in order to avoid an incorrect diagnosis because of connections:
- If testing the vehicle with the battery cables still connected, wiggle the SA9154Z-A clips on the terminals. This may cut through any coating or through any oxidation that may be present on the terminals.
- If the tester displays a "Bad Battery" result for a battery tested in the vehicle with the battery cables connected, perform the following steps:
- Disconnect the negative battery cable.
- Disconnect the positive battery cable.
- Replace the battery only if the Out-of-Vehicle test shows a "Bad Battery" result. This prevents battery replacements that are due only to faulty battery cable connections.
