The ignition mode switch has two LEDs that indicate the vehicle power mode. When the vehicle is in the off mode, both LEDs will be off. Pressing

the ignition mode switch button once, without the brake pedal applied, will enter the accessory mode and the amber LED will illuminate. Pressing

the ignition mode switch button a second time or pressing and holding the ignition mode switch, without the brake pedal applied, will enter the run

mode and the green LED will illuminate. With the ignition off and the brake pedal applied, pressing the ignition mode switch button once, the

vehicle will enter run/start mode and the green LED will illuminate. This will start the engine.

The keyless entry control module supplies the ignition mode switch a constant B+ signal on the ignition switch run signal circuit. The keyless entry

control module monitors this signal to determine the igniting mode. When the ignition mode switch is not pressed, voltage on the signal circuit is

pulled down through two resistors in the switch. When the ignition mode switch is pressed, voltage on the signal circuit is pulled down through

only one resistor, changing the voltage seen at the keyless entry control module and indicating that the ignition mode switch is pressed.

Conditions for Running the DTC

Voltage supplied to the module is in the normal operating voltage range of 9-16 V.

Conditions for Setting the DTC

B097B 02

* The keyless entry control module detects a short to ground in the respective circuit, when the output is inactive.

* The above condition exists for more than 1 second.

B097B 05

* The keyless entry control module detects a open in the ignition mode circuit

* The above condition exists for more than 1 second.

B097B 08

* The keyless entry control module detects a change in the ignition mode without observing a switch press.

* The above condition occurs four consecutive times.

B097B 61

* The keyless entry control module detects a continuously closed ignition mode switch.

* The above condition exists for more than 1 minute.

Action Taken When the DTC Sets

No action is taken.

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.
