Diagnostic Procedure

DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK KEYLESS ACCESS CM. Turn the ignition switch to OFF. Take the access key out of the passenger room. Push the push button ignition switch. Within 30 seconds, use oscilloscope to measure the waveform between connectors. Connector & terminal (i150) No. 14 - (i150) No. 8:	Is the waveform shown in the left column displayed?	Go to step 2 .	Replace the push button ignition switch. < Refer to PUSH BUTTON IGNITION SWITCH . >
2 CHECK HARNESS. Disconnect the keyless access CM connector. Disconnect the push button ignition switch connector. Using the tester, measure the resistance between terminals. Connector & terminal (i150) No. 14 - (i242) No. 1: (i150) No. 8 - (i242) No. 24:	Is the resistance less than 1 Ω?	Go to step 3 .	Repair or replace the open circuit of harness.
3 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground. Connector & terminal (i242) No. 1 - Chassis ground: (i242) No. 24 - Chassis ground:	Is the resistance 10 kΩ or more?	Go to step 4 .	Repair or replace the short circuit of the harness.
4 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground. Connector & terminal (i242) No. 24 - Chassis ground:	Is the resistance 1 Ω or less?	Replace the keyless access CM. < Refer to KEYLESS ACCESS CM . >	Repair or replace the harness.
