Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
Inflator Switch Signal | C0697 02 | 1 | 1 | 1 |
1. Inflator Switch Inoperative |
The air suspension control module (ASCM) monitors the air inflator switch circuit signal for a short to ground with ignition ON and up to 3 minutes with the ignition OFF.
• | Battery voltage is between 9-16 volts. |
• | The ignition is ON or OFF. |
The air suspension control module senses air inflator switch signal circuit voltage shorted to ground.
• | The air suspension system will be inoperative. |
• | No message is displayed. |
The DTC will clear when the condition for setting the DTC is removed.

Control Module References for scan tool information
Ignition ON, Observe the scan tool Inflator Switch parameter while pressing/depressing the inflator switch. The reading should change between Released and Pressed.
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If not the specified value, test the signal circuit connector X452 terminal C for a short to voltage. If the circuit tests normal, test or replace the air suspension control module. |
⇒ | If not the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, replace the air suspension control module. |
⇒ | If not the specified value, replace the Inflator switch. |
⇒ | If greater than the specified range, replace the inflator switch. |
⇒ | If not the specified range, replace the inflator switch. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
