4. Complete Installation
1. MCS CAN Integration
a. Kit Preparation – MCS CAN Integration Harness
Step 1 is to tape up the integration harness.

2. Installation
a. Connect MCS CAN Harness to RTU
Plug the end with the two black Molex plugs directly into the RTU and the OBD harness as seen in the picture below.

b. MCS Can wiring installation
The MCS CAN integration harness should run from the OBD port (this may vary in location dependent on manufacturer) following the side of the vehicle as shown in the below photo’s. Where possible follow the main loom down the side to the MCS controller.

c. Connect to MCS
Unplug the handset plug and plug directly into the MCS CAN harness. Plug the other molex plug on the harness into the port on the MCS controller that has just been vacated.

d. Test MCS output
Test the physical function of the below switches to ensure an event is displayed on the Airmax System when commissioning.
- All events being received – Go to Section 4
- Some Events being received – Go to Section 3
- No Events being received – If no events are being received follow these steps to diagnose the issue
- Is power being received by the MCS Controller?
- Test the outputs on the ‘T’ harness to ensure correct feeds are being received through the MCS CAN harness
- Ensure the Molex plug is correctly fitted to the RTU
- Test the blue and green wire at the RTU’s end, you should have 1.5-2.5v if 0v you have a broken connection.
- If this is all checked and you are unable to receive the Emergency Warning Events (EWE), please contact Airmax Remote customer support.
3. Programme MCS output to meet Airmax Switch Index
4. Complete Installation
a. Ensure all wiring is tidy and runs through, where applicable, pre-existing trunking and the cables are secured correctly down the full length of the vehicle.
b. Refit all panels removed correctly.
