Service Precautions

WARNING: This page is about a different variant/trim than selected.

Before proceeding with system diagnosis, following precautions must be followed:

When using SELF-DIAGNOSTIC TESTS for diagnosis, DO NOT skip any steps, or incorrect diagnosis may result. Always perform indicated verification procedure after repairs are made.
When using a jumper wire, ensure either jumper wire or circuit is fuse-protected.
Before disconnecting connector from any control module, ensure ignition is off before removing connector.
When checking voltage or continuity at any control module, probe connector for control module from pin side. DO NOT backprobe connector or probe wires through the insulation.
DO NOT cause short circuits when performing electrical tests. This will set additional Diagnostic Trouble Codes (DTCs), making diagnosis of original problem more difficult.
Use specific test equipment as specified when performing electrical tests.
