Output

PCM OUTPUT DISPLAYS:

When troubleshooting a malfunction, the PCM output cycling can be used to determine if the output tests can be actuated regardless of the inputs and normal program instructions. Once a test in outputs has been selected, the test will display "HI" and "LO" for three seconds in each state to indicate the command. Actual circuit operation will depend on circuit integrity. If the test selected is not allowed under the current conditions a " =- =- " display will result. A brief summary of each output is provided below:

EO00 The "NO OUTPUTS" display will not display "HI" or "LO" as this is a resting spot where no outputs will be cycled.

EO01 The canister purge solenoid "CAN PURG" display will be "LO" when the solenoid is "ON" (energized).

EO02 The "A/C RELAY" display will be "LO" when the relay is "ON" (energized).

EO03 The "IAC MOTOR" output will cycle "LO" (IAC extending) to "HI" (IAC retracting).

IMPORTANT: This output should not be activated if the IAC has been removed from the throttle body.

EO04 The C/C servo display will display the servo position.

EO05 The coolant fan relay #1 "FAN REL 1" display is "LO" when the coolant fan is "ON" (energized).

EO06 The coolant fan relay #2 "FAN REL 2" display is "LO" when the #2 coolant fan is "ON" (energized).

EO07 The "TCC SOL" display will be "LO" when the TCC solenoid is "ON" (energized).

EO08 The [1][2]torque converter clutch modulating solenoid display will be "LO" when the solenoid is "ON" (energized).

EO09 The transmission shift solenoid A display will be "LO" when the solenoid is "ON" (energized).

EO10 The transmission shift solenoid B display will be "LO" when the solenoid is "ON" (energized).

EO11 The "HOT LIGHT" display will be "LO" when the hot light is "ON."
