Diagnostic Reference Values:

NOTES:
1. A/C ON

2. Brake pedal APPLIED.

3. Monitor in DCV manual mode, reference pin to PWR GND (40/60).

4. HO2S should switch from rich (red LED) to lean (green LED), or lean to rich, at least once every 3 seconds. HO2S voltage should toggle above and below .450 DCV and should never be a negative value.

5. Pin 41 (TCS) is not testable when using the monitor 60 pin adapter.

Reference values shown may vary +/- 20% depending on operating conditions and other factors. RPM values are axle and tire dependent.

**Monitor 60 pin adaptor is required for this vehicle. Running KOER Quick Test with the monitor 60 pin adapter connected will result in a TCS fault.
