Test F2: DTC 26

Diagnosis F: DTC 24, DTC 25 Or DTC 26 Set (Wiring Diagram):

Test F2: DTC 26:

OPERATION:
The DERM tests the deployment loop (both sensors. Inflator module, Ignition feed, and reserve power supply) by measuring voltage through the resistor module. The DERM stores one of the codes If it senses an out of range condition. Each of the codes Is set when a particular condition Is detected.

DTC 24 - Voltage at DERM terminal A6 is between 0 and 41% of reserve power supply voltage for 500 milliseconds.

DTC 25 - Voltage at DERM terminal A6 is within 2 volts of battery.

DTC 26 - Voltage difference between DERM terminals A6 and A7 greater than 0.45 volts.

POSSIBLE CAUSES:
DTC 24 - Low resistance In dual sensor. Improper resistance In either discriminating sensor. 347, 348, 349, 688, 714, 752 or 753 wires shorted to battery or ground. 347 or 752 wire open.

DTC 25 - Steering column wiring shorted to Ignition or battery. 344 or 347 wires shorted to ignition. High resistance In resistor module.

DTC 26 - Open or high resistance In steering column wiring. Short between CKTS 236 and 753. Open In CKTS 347, 348, or 752. Short to ground In CKT 752. Faulty dual sensor or resistor module.
