Using The Mahle ACX1299

Diagnosing Air Conditioning Systems

The automotive A/C system is complex with many sub-systems. All of the sub-systems should be checked before removing the refrigerant.

Start with the basics:

Is the compressor turning? (If belt driven, is the clutch hub turning? If electric, use KDS to check rpm)

Check the blower fan at all speeds

Check for cooling (temperature) at all vents

Using the ACX1299 to monitor the pressures

Use the chart at the end of this TSB to compare pressures and temperatures.

Compressors with an ECV (electric control valve) change pressures as needed.

Use the 07140-10001 “A/C Compressor Diagnostic Kit” to diagnose a variable displacement Electronic Control Valve (ECV type A/C compressors) (refer to TSB SST040).

Use the ACX1299 to recover and recharge (Auto Cycle) the A/C system to ensure the correct amount of refrigerant is in the system. Recharging the system is the only way to check for a full charge in Kia systems.

Attaching the Service Hoses

Installing the Couplers

Install the coupler and then turn the coupler valve clockwise to open. This extends a pin that opens the Schrader valve in the service port.

Removing Couples

Turn the coupler valve counter-clockwise to close the valve, and then remove the coupler.


NOTICE

Monitoring A/C System Pressures

This procedure is used to view A/C system pressures.

1. Attach the service hoses to the vehicle and open the coupler valves.

2. Read the gauges on the face of the ACX1299.

Use the chart on the last page of this bulletin to compare low side pressure and evaporator temperature.

Vehicle Setup

This procedure enters the vehicle information into the ACX1299 using the Mahle VCI or manual entry. When the VIN is entered, the amount of refrigerant is automatically selected and captured for warranty purposes.

Once the vehicle setup is complete, the technician can perform:

Auto Cycle – Used to properly fill the system with refrigerant to check for proper operation. Refrigerant is recovered from the system, a vacuum is applied, and the correct amount of refrigerant is put in.

Manual Service Modes – Recover, Vacuum, and Charge

Recover – Used to recover refrigerant before replacing parts

Vacuum – Used to pull vacuum and check for leaks

Charge – Used to recharge the system


The VIN and RO numbers must be entered for warranty claims.

Finding the Leak When the A/C System will Not Hold a Vacuum

There may be some challenges charging the A/C system when the system has a leak. The SAE requirements do not allow refrigerant to be put in a leaking system.

The R1234yf equipment is required by SAE J2843 to recover, and perform a vacuum hold leak test of the vehicle’s A/C system before allowing a precharge so an electronic leak check can be performed.

In the event the A/C system will not hold vacuum due to a gross leak, the equipment will not charge the A/C system. However, refrigerant must be in the A/C system to locate the leak.

1. Close (counter clockwise) the couplers right before the Vacuum Hold Test. With vacuum locked in the recycling equipment, the Vacuum Hold Test will pass.

2. When the precharge cycle begins, open the couplers (clockwise) to allow the system to accept the precharge.

3. With the precharge in the system, use the ArcticPRO LD-2 Leak Detector to locate the leak. Check for leaks at the floor vents, connectors, hoses, evaporator, condenser, compressor seal, etc.

4. Once the leak is located, use the ACX1299 to recover the refrigerant before opening and repairing the A/C system.

ACX Filter Replacement The ACX1299 monitors the quantity of processed refrigerant. As the filter nears the end of its capacity, the ACX1299 will warn the operator that a replacement will be required soon. It is essential to order or stock a spare combo filter as soon as these warning messages appear.

When the life of the filter expires, the ACX1299 recovery/recycling will be disabled until a replacement is installed. This filter is accessed through the left side panel on the unit.

The red and blue A/C service hoses included with the ACX1299 are equipped with conical inline filters to prevent debris from entering the unit. If during a recovery/recycling process, the service time appears to be longer than normal, it is a good indication that the hose filters should be replaced.

The filter service kit includes one (1) combo desiccant filter and four (4) inline hose filters.

Filter service kit is part number: 36082 73900.

The refrigerant identifier (RFID) on the ACX1299 includes a filter which must be monitored. This filter is located on the top control panel which is easily visible. If this filter appears pink, it indicates that oil has migrated into this device and the filter and/or sample hose assembly should be replaced as soon as possible. Continuing to perform refrigerant identifications under this condition could result in damaging this sensitive and costly device.
