Troubleshooting
Before troubleshooting the immobilizer system,
troubleshoot any EClvl Diagnostic Trouble Codes (DTCS)
(see page 11-3), and make sure the ECM has no
malfunction.
Note these items before trou bleshooting:
. Due to the action of the immobilizer system, the
engine takes slightly more time to start than on a
vehicle without an immobilizer system.. When the system is normal, and the proper key is
inserted, the indicator light comes on for 2 seconds,
then it will go off.. If the indicatorstartsto blink after 2 seconds, or if the
engine does not start. remove any other immobilizer
keys or large key fobs on the key ring, then repeat the
starting procedure.
lf the engine still does not start, continue with thisprocedure.
1. Turn the ignition switch ON {ll) with proper key.
2. Check to see if the immobilizer indicator light
comes on.
Does the indicator light blink?
YES Disconnect the 7P connector from the
immobilizer control unit-receiver, then go to step 9.
NO Check for these problems, then go to step 3.
. Blown No. 9 (10A)fuse in the under-hood
fuse/relay box.I. An open in the wire between the gauge assembly
and the immobilizer control unit-receiver.l. A faulty immobilizer indicator light,I. An open in the wire between the gauge assembly

Troubleshooting lntermittent Failures
lf there was a malfunction, but it doesn't recur. it will be
stored in the memory as an intermittent failure, and the
SRS indicator will come on.
After checking the DTC, troubleshoot as follows:
1. Read the DTC (see "Reading the DTC").
2. Erase the DTC memory (see "Erasing the DTC
Memory").
3. With the shift lever in neutral, start the engine, and
let it idle.
The SRS indicator will come on for about 6 seconds
and then go off.
Shake the wire harness and the connectors. take a
test drive (quick acceleration, quick braking,
cornering), turn the steering wheel fully left and
right, and hold it there for 5 to '10 seconds. lf the
problem recurs, the SRS indicator will come on.
lf you can't duplicate the intermittent failure, the
system is OK at this time.
