ICCS2 Data Link Test

The ICCS2 Data Link Test will ensure that the wires are not crossed between the Electronic Brake/Traction Control Module (EBTCM) and the CVRSS module. The ICCS2 Data Link Test first checks for any EBTCM or CV1tSS DTCs. If any EBTCM or CVRSS codes are set then this test will not run. If the test is successful the scan tool will display a test complete message. If the wires are crossed and this test is run the scan tool will display an electrical malfunction message.
Perform the test as follows:
1. Ignition OFF.
2. Install the scan tool.
3. Turn ignition to RUN.
4. Select ABS/TCS/ICCS2 Special Tests.
5. Select ICCS2 Data Link Left or Right.
6. Wait approximately 15 seconds for a pass or fail response from the scan tool.
