APPLICATIONS

The Bendix ATR-6 Traction Relay Valve, part number 2602215C91, is associated with compatible air brake systems used in selected commercial vehicles, including:

• International / Navistar 4200

• International / Navistar 4300

• International / Navistar 4400

• International / Navistar 7300

• International / Navistar 7400

• International / Navistar 7600

• International / Navistar 5600i and 5900i

• Ford F-650 and F-750 chassis with compatible air brake configurations

Compatibility depends on the vehicle's ABS/ATC system, original valve specifications, and OEM part number.

FUNCTION

The Bendix ATR-6 Traction Relay Valve performs two essential functions within a compatible commercial truck braking system.

During normal service braking, the valve acts as a pneumatic relay, controlling compressed air delivery to the brake chambers.

During traction control operation, its electronically controlled solenoid allows the ABS/ATC controller to supply air pressure to the appropriate brake modulators, helping limit excessive wheel spin.

A worn, damaged, or failing ATR-6 traction relay valve may cause symptoms such as:

• Air leaks around the valve assembly

• Inconsistent service brake response

• ABS or traction control warning lights

• Reduced automatic traction control performance

• Fault codes related to the traction control solenoid

• Improper air pressure delivery to the brake chambers

WHY REPLACE AN ATR-6 TRACTION RELAY VALVE?

A malfunctioning traction relay valve can interfere with air brake operation and automatic traction control performance.

Replacing a defective valve with the correct Genuine OEM Bendix ATR-6 component helps restore proper pneumatic control, reliable service brake response, and intended ABS/ATC system operation.

A correctly functioning traction relay valve is particularly important for heavy-duty commercial trucks operating in wet, icy, or low-traction road conditions.
