Use multimeter to verify proper voltage at the retarder control relay.
Use multimeter to verify proper voltage at the retarder control relay.
Unplug connector at ECU. There should be a voltage between 0 and 2.5 volts on
J1939/J1922 (–) and a voltage between 2.5 and 5.0 volts on J1939/J1922 (+).
Refer to schematic and correct wiring harness as required.

There is too great a difference in the rolling radius of the front and rear tires.
Steer axle tire radius cannot be more than 20% above rears or 10% below. If the
static loaded radius of the rear tires is outside the range 15.9 to 21.5 inches the
ECU must be recalibrated using a diagnostic tool.

Press brake pedal. If error does not clear, check for missing connection at brake
light switch. If the brake is not applied you should measure the resistance of the
brake light bulb (bulb broken?). If the brake is applied, you should measure
vehicle system voltage. (i.e. 9…16v)
Cycle ignition switch and ATC will be re-enabled.
Diagnostic switch may have been pressed for an excessive period of time (>30
seconds). If not check wiring associated with indicator lamp.
This trouble code should clear when the vehicle is driven and the ECU is able
to read sensor output voltage. If this does not happen, verify that the sensors are
properly adjusted (pressed full in to tone wheels.)
Retarder control relay shorted high or
open circuit.
Retarder control relay shorted low.

Note: For codes 17•3 and 17•4 the problem may be
within the engine controller, another controller on the
data link or within the wiring or connectors.
