This procedure covers the removal and replacement of the negative battery cable on a 2019-2024 Toyota RAV4 with the 2.5L I4 gas engine, including all ground connections.

Warnings

Tools required

Parts

• Negative battery cable × 1 — Use OEM specification

Preparation

1. Ensure ignition is OFF and key fob is at least 10 feet away from vehicle
2. Remove any accessories plugged into 12V outlets
3. Open hood and secure with prop rod
4. Locate battery and identify negative terminal (marked with '-' symbol and typically has a black cable)

Procedure

1. 1

   Disconnect negative battery terminal
   Using a 10mm socket, loosen the negative battery terminal bolt. Do not remove the bolt completely, just loosen enough to slide the cable off the terminal post. Lift the cable away from the battery and secure it so it cannot contact the terminal.
   Torque spec

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Remove primary chassis ground connection
   Locate where the negative cable connects to the chassis ground point near the battery tray. Using a 12mm socket, remove the ground bolt securing the cable to the chassis. Note the exact position and any washers or hardware for reassembly.

   Ground Cable Bolt14 Nm (10 lb-ft)
3. 3

   Disconnect secondary ground straps
   Follow the negative cable to locate any secondary ground strap connections to the body or frame. Using a 10mm or 12mm socket as required, remove the ground strap bolts. The RAV4 typically has ground connections near the battery tray and at the engine mounting area.
   Torque spec

   Ground Strap Bolts12 Nm (9 lb-ft)
4. 4

   Remove cable routing clips
   Identify and release any plastic clips or ties securing the negative cable along its routing path. Carefully note the cable routing for proper reinstallation. Take a photo if necessary to reference later.
5. 5

   Remove old negative battery cable
   Once all connections and clips are released, carefully remove the negative battery cable from the vehicle. Inspect the cable for damage, excessive corrosion, or fraying that necessitates replacement.
6. 6

   Clean connection points
   Using a wire brush, clean the battery terminal post, chassis ground connection points, and any ground strap contact surfaces. Remove all corrosion and oxidation. Clean with baking soda solution if heavy corrosion is present, then rinse and dry thoroughly.
7. 7

   Install new negative battery cable
   Route the new negative battery cable following the exact path of the original cable. Ensure the cable does not contact any sharp edges, hot components, or moving parts. Secure routing clips loosely for now.
8. 8

   Connect secondary ground straps
   Attach the ground strap connections to their mounting points on the body or frame. Ensure mating surfaces are clean and making full contact. Install and torque the ground strap bolts to specification.

   Ground Strap Bolts12 Nm (9 lb-ft)
9. 9

   Connect primary chassis ground
   Attach the negative cable to the main chassis ground point near the battery tray. Ensure the contact surface is clean and the cable terminal is fully seated. Install and torque the ground cable bolt to specification.
   Torque spec

   Ground Cable Bolt14 Nm (10 lb-ft)
10. 10

    Connect negative battery terminal
    Place the negative cable terminal over the negative battery post. Ensure it is fully seated and positioned correctly. Install the terminal bolt and torque to specification. Do not overtighten as this can damage the terminal or post.

11. 11

    Secure cable routing
    Ensure all routing clips are properly secured and the cable follows the correct path without excessive tension or slack. The cable should not contact moving components or be subject to chafing.
12. 12

    Apply corrosion protection
    Spray battery terminal connections with anti-corrosion spray or apply a thin layer of dielectric grease to prevent future corrosion. Avoid getting grease on the mating surfaces before connection.

Reassembly

1. Verify all ground connections are tight and properly torqued
2. Ensure negative cable routing matches original configuration
3. Confirm cable does not interfere with any moving components or hot surfaces

Verification

• Attempt to start the vehicle - engine should crank and start normally
• Check that all electrical systems function properly (lights, radio, power windows, etc.)
• Verify no warning lights remain illuminated on the instrument cluster (some may require driving to clear)
• Reinitialize power window auto-up/down feature by fully opening then closing each window while holding the switch
• Reset clock and radio presets as needed
• Visually inspect all ground connections to ensure they are secure with no visible gaps
