Where are the ABS codes on a corvette?

Module 1 CCM (central control module) is first, followed by module 4 ECM (engine control module) and finishing with module 9 ABS/ASR EBTCM (anti-lock brake system/acceleration slip regulation/electronic brake traction control module) codes. 1990-1991 Corvette CCMs will not display any ABS/ASR or EBTCM codes.

When do you turn off the ABS light?

After the broken ABS (Anti-lock Braking System) has been fixed and work properly again, the light will go off. How to turn off the ABS light is actually to get the Anti-lock Braking System fixed. 2. Can You Drive With An ABS Light On?

What happens if you don’t have an ABS system?

If that controller gets insufficient data, or a hydraulic pump or valve isn’t responding, it illuminates the ABS warning light on the dashboard. ABS relies on a properly operating conventional brake system. If the rest of your braking system is in working order, you should usually still have normal braking without ABS.

How does the ABS work when the wheel stops rotating?

ABS sensors tell a computer (called a controller) when a wheel stops rotating while the car is in motion, which indicates that the brakes have locked up at that particular wheel. The controller then directs a hydraulic valve to release some brake fluid pressure to the wheel in order to let it rotate again.

Module 1 CCM (central control module) is first, followed by module 4 ECM (engine control module) and finishing with module 9 ABS/ASR EBTCM (anti-lock brake system/acceleration slip regulation/electronic brake traction control module) codes. 1990-1991 Corvette CCMs will not display any ABS/ASR or EBTCM codes.

What happens when the ABS system is not working?

The sensors detect wheel speed, and will send a message to the ABS module to rapidly pump the brakes when it is detected that the vehicle is skidding or has lost traction. When the ABS system is not functioning then loss of traction, skidding, and hydroplaning are far more likely to occur under heavy braking conditions.

Can a bad ABS cause a brake line to bleed?

An insect the hydraulic system for defects or failures from the master cylinder, bad calipers, leaking wheel cylinder, or even a bad ABS. Irrespective of the kind of ABS you are using, it is imperative that you know how to restore the brake pedal to its normal height.

Do you need to bleed the ABS module?

Once your brake lines are properly bled, you can continue further troubleshooting. If the brakes still don’t feel right after you have properly flushed the brakes, then you might need to bleed the ABS module itself. Even without the help of an ABS scan tool, bleed methods can be performed safely and accurately.

What kind of trouble does a 1993 Corvette have?

Any loose strands could short another terminal. 1990-1993 Corvettes use the first generation ALDL connector. It houses a fuel pump override lead that has battery voltage. This connector position can harm other ALDL circuits if battery voltage is inadvertently jumped to a control circuit.

What are the trouble codes on a 1996 Corvette?

In addition, ABS/ASR (Anti-lock Brake System/Acceleration Slip Regulation) and EBTCM (Electronic Brake Traction Control Module) trouble codes and data were introduced on the 1992-1996 Corvettes. Although limited ECM data is available, it can point you in the right direction.

What does SYS stand for on a corvette?

Have you noticed “SYS” intermittently showing up in your 1990-1996 Corvette’s speedometer display? This means there is a trouble code stored in one of the on-board control modules. When the 1990 Corvette debuted, GM introduced ECM (Engine Control Module) and CCM (Central Control Module) trouble codes.

What are the trouble codes for a corvette?

31 LCD data circuit shorted to battery or CCM internal open 33 Data clock circuit shorted to battery or CCM internal open circuit 35 Data strobe circuit shorted to battery or CCM internal open circuit 36 Data strobe circuit open or shorted to ground 37 M clock circuit shorted to battery or CCM internal open circuit

Where do I find the CCM code on my Corvette?

The CCM will display all module codes (sequentially) in the speedometer read-out area.

How to turn off traction control on a C5 Corvette?

Turning off the TCS in the C5. To turn the traction control off on the C5, the driver needs to press the TCS button one time. When the TCS is turned off, a symbol of the back of the car with two wavy lines will light up in the instrument panel. This symbol is to the right of the Corvette logo that is in the center of the speedometer.

What causes the traction control to go offline?

The traction control computer in your vehicle is the “brain” that controls the entire system. A defect, corroded contacts or water damage in this computer can result in the entire system going offline, which will turn on the TCS warning light. As the TCS and ABS often share a computer, this may affect your ABS system and turn on that light, too.

How do you turn off traction control on a car?

Many vehicles with traction control have a switch that lets you temporarily turn it off. The switch is usually marked “TCS Off” or “ESC Off.” Once you switch it off, it will stay off until you either switch it back on or turn off and restart your vehicle.

Where is the traction control in a 98?

Only 97 and early 98 have the module in the rear. The other ones have it in the front close to the steering rack. The number I have on my part CD are 9355246 for the EBTCM and 15227809 for the BPMV. I always check with dealer to confirm part number sometimes it changes.

How to clear a CCM code on a corvette?

Clearing the CCM codes can be done after the automatic sequence of codes has occurred with the following instructions: Press the TRIP RESET button until “1.0” is displayed in the module number area. Then press the TRIP/ODO button until “1.7” is displayed in the module number area. Once there, press and hold the ENG/MET button until “—“is displayed.
