Walk Away Braking Relay Test with the IQDM Handset
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Connect the IQDM to the vehicle.
See Plugging the Handset into the Vehicle, Section 12, Page 12-1.
3. Check the FAULTS Menu.
4. If a 15 RELAY DNC or 30 RELAY COIL FAULT is shown in the list, a walk away braking fault has
occurred.
Walk Away Braking Relay Test without the IQDM Handset
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Slowly push the vehicle a short distance (about 3 feet (1 meter)).
3. You should feel resistance as motor braking is applied. The reverse buzzer will also begin pulsing. If nei-
ther of these conditions are present, test the Motor Speed Sensor.
If the Motor Speed Sensor is operational, replace the walk away braking
relay.
