Sensor Test Mode

  1. Put system into ATM Test Mode. Press and hold ATM button until the desired sensor access code is displayed. Release ATM button. Move read/hold switch to "HOLD" position.
    NOTE: Since sensor access codes are the same as some ATM test codes, the ATM circuit will turn on before moving the read/hold switch to the "HOLD" position.
  2. The logic module will use the readout box to display the output of the selected sensor. Divide all displayed readings except coolant sensor and battery voltage by 10 for actual reading. Multiply coolant sensor readings by 10 for actual readings. Battery voltage readings are actual and no correction is necessary.
