Brakes are spongy but I am getting no air out of brake lines. Also, when brakes are pumped and held it takes a few seconds for brakes to hold the wheel from spinning.
Do you
have the same problem?

Good afternoon.

There is no special bleeding for the ABS. It is not like the GM that requires a scan tool.

Here is a video and guide below to help you bleed the brake system correctly.

Please run down these guides and report back.I would suspect a master cylinder issue from your description.

Four Wheel Anti-Lock Brake System (4WABS) Hydraulic Control Unit (HCU)

WARNING: Use of any other than approved DOT 3 brake fluid will cause permanent damage to brake components and will render the brakes inoperative. Failure to follow these instructions may result in personal injury.

WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. Failure to follow these instructions may result in personal injury.

CAUTION: Brake fluid is harmful to painted or plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.

CAUTION: Do not allow the master cylinder to run dry during the bleeding operation. Keep the master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system.

NOTE: This procedure only needs to be carried out if a new 4-wheel anti-lock brake system (4WABS) hydraulic control unit (HCU) has been installed.

1. Clean the area then remove the brake master cylinder filler cap, and fill the brake master cylinder reservoir with the specified brake fluid.
2. Connect a clear drain tube to the RH rear bleeder screw and the other end in a container partially filled with the recommended DOT 3 motor vehicle brake fluid.
3. Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
4. Loosen the RH rear bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the bleeder screw.
Repeat this step until clear, bubble-free fluid comes out.
Refill the brake master cylinder reservoir as necessary.
5. Tighten the bleeder screw.
Tighten to 15 Nm (11 ft. lbs.).
6. Repeat Steps 2 through 5 for the LH rear bleeder screw, the RH front bleeder screw and the LH front bleeder screw, in that order.
7. Connect the diagnostic tool adapter cable into the vehicle data link connector (DLC) under the dash, and follow the diagnostic tool instructions for bleeding.
