   M101	3	Ground	Battery voltage

   Is the inspection normal? 

   YES: GO TO 2.

   NO-1: Check 10 A fuse [No. 9, located in fuse block (J/B)].

   NO-2: Check harness for open or short between push-button ignition switch and fuse.

2. CHECK BCM INPUT
   1. Connect push-button ignition switch connector.
   2. Disconnect BCM connector.
   3. Check voltage between BCM connector and ground.

   Is the inspection normal? 

   YES: Replace BCM. Refer to "REMOVAL AND INSTALLATION ".

   NO: GO TO 3.

3. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT

1. Disconnect push-button ignition switch connector.
2. Check continuity between BCM harness connector and push-button ignition switch harness connector.
