Test 7 - When DTC No. 24 Or No. 25 Is Displayed

TEST 7 - WHEN DIAGNOSTIC TROUBLE CODE No. 24 OR No. 25 IS DISPLAYED
(From 1994 models)

Caution: Never attempt to measure the circuit resistance of the passenger's air bag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental passenger's air bag deployment will result in serious personal injury.

PROCEDURES





NOTE: If combined front impact sensor and passenger's air bag module (squib) failure modes simultaneously occur in two places, the preconditions for the respective detection circuits will go out of order. For this reason, both diagnostic trouble codes may not be stored but only one of them may be indicated.





Their relationships are shown in the table above.

Perform TEST 5 Test 5 - When DTC No.11, No. 12 Or No. 13 Is Displayedif it does not become proper even through TEST 7 Test 7 - When DTC No. 24 Or No. 25 Is Displayedis executed.

The numbers in the boxes are diagnostic trouble codes numbers.





(1) Turn the ignition key to the "LOCK" position, disconnect the negative battery cable and tape the terminal.

Caution: Wait at least 60 seconds after disconnecting the battery cable before doing any further work. The SRS system is designed to retain enough voltage to deploy the air bag even after the battery has been disconnected. Serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cable is disconnected.

(2) Disconnect the passenger's air bag module connector from the body wiring harness connector.
(3) Connect the SRS check harness connector (1) to the body wiring harness connector.





NOTE: A 3-ohm resistor that corresponds to the resistance of the passenger's air bag module (squib) and the wiring resistance is connected between the terminals of the connector (1) of the SRS Check Harness.

(1) Reconnect negative terminal of battery.

PAGE REFERENCE:

(2) Use the scan tool (when connecting the scan tool (MUT-Il) to a vehicle up to 1993 model, use the adapter harness supplied together).

Caution: Before connecting or disconnecting the scan tool, make sure that the ignition switch is placed at the OFF position.

(3) Turn the ignition key to the "ON" position, erase the diagnostic trouble code memory.
(4) Return the ignition key from the "ON" to the "LOCK" position and then back to the "ON" position.

Caution: Never attempt to measure the circuit resistance of the air bag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental air bag deployment will result in serious personal injury.

NOTE - IMPORTANT:
(2) After repairing the SRS, reconnect the battery cable, erase the diagnostic trouble code memory from the scan tool and check the SRS warning light operation to verify the system functions properly. Refer to TEST 1. Test 1 - SRS Warning Light Does Not Extinguish
