This procedure covers removal and replacement of the positive battery cable on a 2012-2017 Toyota Camry with the 2.5L I4 engine, including disconnection from battery terminal and all connection points.

Warnings

Tools required

Parts

• Positive battery cable assembly × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Open hood and secure with hood prop
4. Identify battery location in engine bay (driver side)
5. Allow engine to cool if recently operated

Procedure

1. 1

   Disconnect negative battery terminal
   Using a 10mm socket, loosen the negative (-) battery terminal bolt. Remove the negative cable from battery post and secure it away from the battery to prevent accidental contact.
2. 2

   Disconnect positive battery terminal
   Using a 10mm socket, loosen the positive (+) battery terminal bolt. Carefully remove the positive cable from the battery post, ensuring it does not contact any metal surfaces.
3. 3

   Remove battery hold-down if necessary
   If the battery hold-down bracket restricts access to the positive cable routing, remove the battery hold-down bolt using a 10mm socket and set aside the bracket. Note the orientation for reinstallation.

   Battery Hold-Down Bolt11 Nm (8 lb-ft)
4. 4

   Trace and access cable connections
   Follow the positive battery cable from the battery terminal. The cable runs to the engine compartment fuse box and starter motor. Identify all connection points along the cable route including the main fuse box connection.
5. 5

   Disconnect positive cable from fuse box
   Locate the positive cable connection at the underhood fuse/relay box. Remove the protective cover if present. Use a 12mm socket to remove the mounting bolt securing the cable terminal to the fuse box junction. Carefully pull the cable terminal free.
6. 6

   Remove cable mounting clips
   Locate and release any cable routing clips or ties securing the positive cable along its path. Note the exact routing and clip positions for proper reinstallation. Remove all fasteners securing the cable.
7. 7

   Remove old positive cable
   Once all connections and clips are removed, carefully extract the old positive battery cable from the vehicle. Check the cable routing path for any damage or wear to surrounding components.
8. 8

   Clean connection points
   Use a wire brush or battery terminal cleaner to clean the battery post and all connection terminals. Remove any corrosion from the fuse box junction point. Ensure all mating surfaces are clean and bright.
9. 9

   Route new positive cable
   Route the new positive battery cable along the same path as the original, ensuring it does not contact sharp edges, hot surfaces, or moving components. Verify the cable reaches all connection points without tension or strain.
10. 10

    Connect cable to fuse box
    Position the positive cable terminal onto the fuse box junction stud. Install the mounting bolt and tighten using a 12mm socket. Ensure the terminal sits flush and makes full contact with the junction surface.
11. 11

    Secure cable routing clips
    Reinstall all cable routing clips and fasteners in their original positions. Ensure the cable is secured along its entire length with no excessive slack or tight spots. Cable should not interfere with any moving parts.
12. 12

    Reinstall battery hold-down
    If removed, position the battery hold-down bracket over the battery in its original orientation. Install the hold-down bolt and tighten to specification using a torque wrench. Do not overtighten as this can damage the battery case.
    Torque spec

    Battery Hold-Down Bolt11 Nm (8 lb-ft)
13. 13

    Connect positive battery terminal
    Place the positive cable terminal onto the positive battery post. Ensure it is fully seated. Apply dielectric grease if desired. Install the terminal bolt and tighten to specification using a torque wrench. Do not overtighten.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
14. 14

    Reconnect negative battery terminal
    Place the negative cable terminal onto the negative battery post. Ensure it is fully seated. Install the terminal bolt and tighten to specification using a torque wrench. Do not overtighten.

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Verify all cable connections are tight and secure before closing hood
2. Ensure positive cable does not contact any sharp edges or hot engine components
3. Replace any protective covers removed from fuse box or junction points

Verification

• Turn ignition to ON position (do not start) and verify dash lights illuminate normally
• Check that all electrical systems function properly (windows, radio, lights)
• Start engine and verify normal operation with no warning lights
• Visually inspect positive cable routing to confirm no interference with moving components
• Check battery terminals for tightness - they should not move by hand
