10. If all circuits test normal, replace the S38 ignition mode switch.
Component Testing
1. Ignition OFF, disconnect the harness at the S38 ignition mode switch.
2. Place a jumper wire between ignition mode switch terminal 4 and ground.
3. Place a fused jumper wire between the circuit terminals of the ignition mode switch listed below and B+:
* Ignition mode switch terminal 2
* Ignition mode switch terminal 5
瀚慖f the either LED does not light, replace the S38 ignition mode switch.
4. Without the button pressed, test for 4,870 ohm between the ignition mode switch terminals listed below:
* Ignition mode switch terminals 3 and 7
* Ignition mode switch terminals 4 and 6
瀚慖f not the specified value, replace the S38 ignition mode switch.
5. With the button pressed, test for 1,300 ohm between the ignition mode switch terminals listed below:
* Ignition mode switch terminals 3 and 7
* Ignition mode switch terminals 4 and 6
瀚慖f not the specified value, replace the S38 ignition mode switch.

Circuit/System Description
Note: Depending on the vehicle build date and BCM software level, the method to place the vehicle in the run mode will be different. Early
vehicles that have not had the BCM replaced or reprogrammed will require two presses of the igniting mode switch to enter run mode. Late
vehicles and vehicles that have had the BCM replaced or reprogrammed require the ignition mode switch be pressed and held for 5 seconds to enter
