Scan Tool Data Definitions - Dash Integration Module (DIM)

DIM - A/C Information - A/C Clutch (Actual): The scan tool displays On or Off. On is displayed when the PCM has energized the A/C clutch relay.

DIM - A/C Information - A/C Clutch (Desired): The scan tool displays On or Off. On is displayed when the IPM is requesting A/C system operation and the DIM has determined that none of the system performance limits are exceeded.

DIM - A/C Information - Control Head (Desired): The scan tool displays A/C On or A/C Off. A/C On is displayed when the IPM is requesting A/C system operation.

DIM - A/C Information - A/C Pressure: The scan tool displays 0 to 4000 kPa (0 to 580 psi). The output of the A/C pressure sensor provided by the PCM over the Class 2 communication link.

DIM - A/C Information - Pressure Status: The scan tool displays Low, Normal or High. Normal must be displayed to allow A/C operation.

DIM - A/C Information - Temperature Status: The scan tool displays Hot or OK. Hot is displayed when engine coolant temperature rises above 121°C (250°F). OK must be displayed to allow A/C operation.

DIM - A/C Information - Clutch Voltage: The scan tool displays Low or Normal. Low is displayed when the battery voltage is low, such that clutch slippage is possible.
