B097B 08
* The BCM detects a difference between the ignition mode switch voltages to the BCM and PEPS module.
* The above condition exists for more than 1 second.
B097B 61
* The BCM and the PEPS module detect a continuously closed ignition mode switch.
* The above condition exists for more than 1 minute.
Action Taken When the DTC Sets
The BCM disables the respective output until the next ignition cycle.
Conditions for Clearing the DTC
* A current DTC clears when the malfunction is no longer present.
* A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.

Circuit/System Verification
Without the brake pedal applied, push the ignition mode switch button twice. Observe the operation of the ignition mode switch LED's. The amber
LED should light after the first button push and the green LED should light after the second button push. The engine should not crank and the
ignition mode should be run.
With the brake pedal applied, push the ignition mode switch once. Observe the operation of the ignition mode switch LED's. The green LED should
light after one button push. The engine will crank.
Circuit/System Testing
B097B 61
Verify DTC B097B 61 is not set.
If DTC B097B 61 is set in both the BCM and PEPS module, replace the S38 ignition mode switch.
B0978 01, B0978 02, B0978 04, B097B 00, B097B 02, B097B 04, B097B 08, B097C 01, B097C 02, B097C 04
1. Ignition OFF, disconnect the harness connector at the S38 ignition mode switch.
2. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down. Test for less than 15 ohm
between the ignition mode switch terminal 4 and ground.
瀚慖f greater than specified range, test the circuit for an open/high resistance.
