CODE 41 - HIGH RESISTANCE OR OPEN RIGHT FRONT IMPACT
SENSOR CIRCUIT
NOTE: Before proceeding, see SERVICE PRECAUTIONS. After servicing
has been performed, recheck AIR BAG warning light for codes
with Air Bag Simulators (105-00010) still in place of air
bag modules. If system is okay, install air bag modules and
reactivate air bag system.
Description
Voltage at terminal No. 17 (circuit No. 617), of diagnostic
monitor connector, is maintained at 9-11 volts. Circuit No. 617 is
connected to circuit No. 624, inside right front impact sensor. If
voltage at terminal No. 2 drops below voltage at terminal No. 17, Code
41 is set.
Possible Causes
Code 41 will set if there is an open circuit in circuit No.
617 or circuit No. 624. Code 41 will also set if there is an open
circuit in the right front impact sensor.
1) Verify Condition - Turn ignition on. Check for fault
codes. If Code 41 is flashing, go to step 2). If Code 41 is not
flashing, check connectors, wiring and crimps for an intermittent
problem. DO NOT proceed with diagnostic test unless code is flashing.
Doing so will result in needless replacement of system components.
2) Deactivate System - Deactivate air bag system. See
COMPLETE SYSTEM DEACTIVATION under DISABLING & ACTIVATING AIR BAG
SYSTEM. Disconnect air bag diagnostic monitor. Measure resistance
between terminals No. 2 and 17 of diagnostic monitor connector. If
resistance is less than 2 ohms, replace diagnostic monitor. If
resistance is greater than 2 ohms, go to step 3).
3) Disconnect right front impact sensor from harness. Measure
resistance between Pink/Orange and Yellow/White wires in sensor
connector. If resistance is less than 2 ohms, locate and repair open
circuit in circuit No. 617 or circuit No. 624. If resistance is
greater than 2 ohms, replace right front impact sensor.
