35 Part 1 of 2

Code 35 Part 1 OF 2:

SIR Wiring Diagram:

DESCRIPTION:

Code 35 is set when the voltage at the "Sense Low" input, terminal A6, is between 61% and 78% of the 36VLR output voltage for 500 milliseconds during the "Continuous Monitoring" tests performed by the DERM. The "Continuous Monitoring" tests are performed by the DERM after the initial "Turn-ON" tests are completed and are performed every 100 milliseconds while "Ignition 1" voltage is present at the DERM. If one of the discriminating sensors is open, the voltage at the "Sense Low" input will increase due to the increase in the resistance of the discriminating sensor section of the deployment loop and Code 35 will set.

TEST CONDITIONS:

Tested every 100 milliseconds during Continuous Monitoring.

FAILURE CONDITIONS:

Code 35 will set if the voltage at the "Sense Low" input, terminal A6, is between 61% and 78% of 36VLR output voltage for 500 milliseconds and the 36VLR output voltage is greater than 28.4 volts and less than 44 volts.

ACTION TAKEN:

DERM turns ON the "INFL REST" warning lamp.

CONDITIONS TO CLEAR:

Current Code 35 will clear if the voltage at the "Sense Low" input, terminal A6, is between 41% and 61% of "36VLR" output voltage for 500 milliseconds.

TEST DESCRIPTION: Number(s) below refer to circled number(s) on the diagnostic chart.

1. This test determines if a fault exists in the discriminating sensors or associated wiring.

2. This test determines if a fault exists in the fwd sensor or associated wiring.

3. This test checks the value of the diagnostic resistor in the fwd sensor.

4. This test checks for an open circuit along the entire harness length of CKT 349 including internal sensor nodes, pigtails and connectors.

5. This test checks for wiring or connector faults which may cause the open condition.
