Coolant temperature 2. Engine load 3. RPM 4. O2 factor 5. Idle Adapt 6. Part throttle adapt 7. Low load adapt 25
Expert Mode Using Expert Mode 8. IAC adapt 9. Not used 10. IGN timing The display fields are output in binary numbers. To understand the binary number, visualize a clock with 0 at the top center. The number 128 is at the center bottom. The binary clock counts from 0 to 255, a rich/lean correction from base midpoint (0). In binary output 0–255, based on O2S output, numbers fluctuate between rich (high numbers) and lean (low numbers). The number can theoretically range from 0 to 255 with 0 as the midpoint. A number of 13 to 128 indicates that the control module has commanded an overall lean mixture correction. A number of 128 to 243 indicates that the control module has commanded an overall rich mixture correction. Example 4: Late Model Motronic 7.5 The following example concerns display group 000 for 1-bank systems: 1. Engine coolant temperature 2. Load 3. RPM 4. Voltage 5. Throttle valve potentiometer 6. Idle air control valve 7. Idle air control valve learning value 8. Lambda control 9. Lambda control learning value idle 10. Lambda control learning value partial load Display group 000 for 2-bank systems: 1. Engine coolant temperature 2. Load 3. RPM 4. Throttle valve angle 5. Idle air control 6. Idle air control valve learning value 7. Lambda control Bank 1 8. Lambda control Bank 2 9. Lambda adaptation (add) Bank 1 10. Lambda adaptation (add) Bank 2 Example 5: Central Electronic Unit (09) The four display fields for display group 012 indicate the following: • Display field 1: Check bus—This field indicates whether the data bus is OK or faulty (e.g. fault in single wire). 26
