Possible Causes

Code 24 will set if there is an open circuit or high resistance in safing sensor or wiring harness Orange/Blue wire or Brown/White wire. Intermittent battery voltage at terminal No. 13 of diagnostic monitor can cause reference voltage inside of diagnostic monitor to fluctuate and cause Code 24 to set in some circumstances.

1. VERIFY CONDITION  - Turn ignition on. Check for fault codes. If Code 24 is flashing, go to step 2). If Code 24 is not flashing, check connectors, wiring, splices and crimps for an intermittent problem. DO NOT  proceed with diagnostic test unless Code 24 is flashing. Failure to do so will result in unnecessary replacement of system components.
2. DEACTIVATE SYSTEM  - Deactivate air bag system. See COMPLETE SYSTEM DEACTIVATION  under DISABLING & ACTIVATING AIR BAG SYSTEM  . Turn ignition switch from OFF to RUN position. Measure voltage between terminals 3 (Black/Red) and 13 (Orange/Green) of diagnostic monitor. Record this voltage as system voltage.
3. Measure voltage between terminal 3 and terminals 11 (White/Blue) and 12 (Brown/White) of diagnostic monitor connector. Using these voltage readings, and system voltage measured in step 2), determine if voltage at terminals No. 11 and 12 are within specification. See VOLTAGE SPECIFICATIONS (CODE 24)  table. If voltage at both terminals is within specification, check Orange/Green wire between fuse block and terminal 13 for an intermittent open. Repair as necessary. If wiring is okay, replace diagnostic monitor. If voltage at both terminals is low, go to step 4). If voltage at terminal 11 is high and voltage at terminal 12 is low, go to step 5).

   4.0	15.0

4. CHECK HARNESS RESISTANCE  - Turn ignition switch to OFF position. Disconnect both battery cables and diagnostic monitor. Measure resistance between terminal 3 (Black/Red) and terminal 11 (White/Blue) at diagnostic monitor Gray connector. If measured resistance is infinite, replace diagnostic monitor. If resistance is less than infinite, locate and repair short to ground in wiring harness, driver-side air bag module, passenger-side air bag module, or sliding contact.
5. CHECK SAFING SENSOR  - Disconnect safing sensor. Measure resistance between sensor terminals (Orange/Black and Brown/White). If resistance is more than 2 ohms, replace safing sensor. If resistance is less than 2 ohms, locate end repair open circuit in Orange/Black or Brown/White wire between safing sensor and diagnostic monitor.
