5 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground, and between antenna connector and chassis ground. Connector & terminal (i242) No. 20 - Chassis ground: (B66) No. 3 - Chassis ground:	Is the resistance 10 kΩ or more?	Go to step 6 .	Repair or replace the short circuit of the harness.
