Tools required

Parts

• Negative battery cable × 1 — Use OEM specification

Preparation

1. Ensure ignition is off and key is removed from vehicle
2. Ensure all electrical accessories are turned off
3. Open hood and secure in upright position
4. Locate battery in engine compartment (driver side rear corner)
5. Note radio security codes and preset stations if applicable

Procedure

1. 1

   Loosen negative battery terminal clamp
   Using a 10mm wrench or socket, loosen the bolt on the negative battery terminal clamp (marked with minus sign or 'NEG'). Do not remove the bolt completely, just loosen it enough to remove the cable clamp from the battery post. If the clamp is stuck on the post, use a battery terminal puller to avoid damaging the post.
2. 2

   Remove negative cable from battery post
   Lift the negative cable clamp straight up off the battery post. Move the cable away from the battery post and secure it so it cannot accidentally contact the terminal during the remainder of the procedure. Tuck it to the side of the battery or tie it back with a zip tie temporarily.
3. 3

   Locate body ground connection point
   Follow the negative battery cable from the battery to its ground point on the chassis. The primary ground is typically located on the inner fender or frame rail near the battery. Inspect the cable routing and note any additional ground straps or connections along its path.
4. 4

   Remove chassis ground fastener
   Using a 13mm socket and ratchet with extension, remove the bolt securing the negative cable terminal to the chassis ground point. The cable end has a ring terminal that slides off the stud or bolt once the fastener is removed. Note the exact position and any washers or other cables sharing this ground point for proper reassembly.
   ℹ️Multiple ground straps or cables may share this connection point. Note their layering order for correct reinstallation.
5. 5

   Inspect cable routing and supports
   Before fully removing the cable, trace its path and note any cable clips, routing guides, or tie-downs that secure it to the chassis or engine bay components. Remove or release these as needed to free the cable completely. The cable may have 1-2 routing clips along its length.
6. 6

   Remove negative battery cable
   With both ends disconnected and all routing clips released, remove the negative battery cable from the vehicle. Inspect the cable for any signs of damage, corrosion, fraying, or cracking of the insulation. Check both terminal ends for corrosion or damage.
7. 7

   Clean battery post and ground point
   Use a wire brush to clean the negative battery post and the chassis ground mounting surface. Remove any corrosion, oxidation, or dirt. If corrosion is present, clean with a baking soda and water solution, then rinse with clean water and dry thoroughly. A clean connection ensures proper electrical contact.
8. 8

   Install new negative cable to chassis ground
   Position the ring terminal of the new negative cable onto the chassis ground stud or bolt location. Ensure it is seated flat against the mounting surface with metal-to-metal contact. If multiple ground straps share this point, reinstall them in the same layering order as removed. Install the 13mm bolt and tighten securely to create a solid ground connection.
9. 9

   Route cable and secure with clips
   Route the new negative battery cable along the same path as the original, ensuring it does not contact hot engine components, sharp edges, or moving parts. Reinstall all routing clips and tie-downs to secure the cable in place. Ensure the cable has adequate slack and is not under tension.
10. 10

    Connect negative cable to battery post
    Place the negative cable clamp onto the negative battery post. Ensure it is fully seated on the post with good contact. Using a 10mm wrench or socket, tighten the clamp bolt securely. The connection should be tight enough that the cable cannot be twisted or pulled off by hand, but do not overtighten and strip the threads.

Reassembly

1. Verify negative cable is securely fastened at both battery terminal and chassis ground point
2. Ensure cable routing does not interfere with any moving components or hot engine surfaces
3. Check that all cable routing clips are properly installed

Verification

• Verify the negative cable terminal cannot be moved or twisted on the battery post
• Confirm the chassis ground connection is tight and making solid metal-to-metal contact
• Turn ignition to ON position (do not start) and verify dash lights illuminate normally
• Start the engine and verify it starts normally without electrical issues
• Check for proper operation of electrical accessories (lights, radio, power windows)
• Verify no warning lights related to electrical system are illuminated on dash
• Reset clock and radio presets as needed
