CODE 25 ± DRIVER AIR BAG INITIATOR CIRCUIT SHORT TO POWER CIRCUIT (Page 1 of 2)
CAUTION:
When measurements are requested in this chart use specified digital multimeter with correct terminal
adapter from special tool (Connector test adapter kit).
When a check for proper connection is requested refer to ªIntermittent and Poor Connectionsº in this
section.
When an open in air bag wire harness, damaged wire harness, connector or terminal is found, replace
wire harness, connectors and terminals as an assembly.
DTC WILL SET WHEN:
The voltage measured at driver air bag initiator circuit is above a specified value for specified time.
NOTE:
Before executing items in this table, be sure to perform ªAir Bag Diagnostic Check Flow Tableº.
STEP
ACTIONYESNO
11) With ignition switch OFF, disconnect contact
coil connector located near the base of the
steering column.
2) Check proper connection to contact coil at
terminals in ªCº connector.
3) If OK then connect Special Tool (B) to contact
coil connector disconnected at step 1).
4) With ignition switch ON, is DTC 25 current?Go to step 2.Go to step 3 on the
next page.
21) With ignition switch OFF, disconnect Special
Tool (B) and SDM.
2) Measure voltage from ªA7º terminal to body
ground.
3) With ignition switch ON, is voltage 1 V or less?Substitute a known-
good SDM and
recheck.Repair short from ªGº or
ªG/Rº wire circuit to
power circuit.
