Terrain FWD L4-2.4L (2010)
Any current flow through a ground or low reference circuit, while being tested, will skew the DMM continuity reading, or display a reading higher than
when there is no current flowing. Performing a ground or low reference circuit continuity test, in reference to the vehicles battery negative terminal, will
have the highest risk of failing a good ground or low reference circuit test than any other ground reference point. The best ground test points would be a
control module housing (if the control modules housing is metal and grounded), door jamb striker (if attached to metal), under dash metal frame work,
engine block, or body ground studs (other than where the negative battery cable is attached).
A typical DMM ground or low reference circuit continuity reading can be as high as 100 ohm with the ignition ON, and drop to 15-25 ohm after the
ignition is turned OFF. The reading will drop below 10 ohm after 30-40 seconds, then below 5 ohm after 60 seconds. Once the vehicle completely goes
to sleep (generally 3-10 minutes) the reading will drop below 0.3 ohm.
The following list of conditions may need to be met to ensure a valid continuity reading on a ground or low reference circuit:
*
Ignition OFF
*
Key out of the ignition switch (when not equipped with keyless entry and remote start)
*
Retained Accessory Power (RAP) OFF (open and close the driver door after ignition OFF)
*
Battery charger set at a 2 A or less charge rate
*
Scan tool not communicating with any vehicle control module (in some cases it may need to be disconnected from the DLC)
*
All entry doors closed
*
Headlamps OFF (auto headlamps disabled)
*
Any delay lighting OFF
*
HVAC after blow OFF
*
Any accessory that can work when the ignition is OFF
*
Wait up to 60 seconds (after all other listed conditions are met)
Activating the DOOR LOCK function with a key fob can greatly reduce the time to achieve a valid ground or low reference continuity test result.

For equivalent regional tools, refer to Special Tools (See: Power and Ground Distribution/Tools and Equipment).
Note: All repairs near the engine manifold, turbo engine and all exhaust pipes should follow the High Temperature Wiring Repair procedures.
1. Find the appropriate connector end view within the connector end view section. The connector end view has the following information:
*
Diagnostic probe tool
*
Terminal release tool
*
Terminal/terminated lead part numbers
2. Determine if a terminal is damaged.
Note: Not using the proper test kit probe may cause damage to the terminal(s) that are probed.
*
Locate the diagnostic probe tool from the connector end view. The connector end view describes the color and part number to help the
technician find and use the correct tool.
*
Connect the probe tool to the Digital Multimeter.
*
Insert the probe tool into the cavity and follow the procedures from the Troubleshooting with a Digital Multimeter (See: Testing and
Inspection/Component Tests and General Diagnostics/General Electrical Diagnostic Procedures/Circuit Testing/Troubleshooting with a Digital
Multimeter).
3. Disconnect the connector body to perform the repair.
Note: Several procedures for specific connector bodies are called out in Wiring Repairs (See: Testing and Inspection/Component Tests and General
Diagnostics/General Electrical Diagnostic Procedures/Wiring Repairs/Wiring Repairs).
Use the following repair procedures to repair the following terminals:
