Diagnostic Mode

DIAGNOSTIC MODE
To enter diagnostic mode, a vehicle speed must be below 10 km/h (6 mph) and no ABS/TCS condition present. If vehicle speed is not below 10 km/h (6 mph), a "No Response" message could be displayed by the DRBIII. The following are characteristics of diagnostic mode:
- The amber ABS warning indicator will blink rapidly (about 1/2 second ON and 1/2 second OFF). If a hard trouble code, such as CAB Power Feed Circuit Failure code is present, the indicator will be illuminated without blinking until the trouble condition is cleared
- Antilock operation is disabled.
- Valve actuation with the DRBIII is disabled when the vehicle speed is above 8 km/h (5 mph). If valve actuation is attempted above 8 km- (5 mph), a "No Response" message will be displayed on the DRBIII.
