8G-22 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
DTC13 NO TRANSPONDER CODE TRANSMITTED OR COIL ANTENNA OPENED/
SHORTED
DESCRIPTION:
Immobilizer Control Module energizes the coil antenna when the ignition switch is ON and reads Transponder code
from the ignition key. When Immobilizer Control Module cannot read Transponder code from the ignition key even
when the coil antenna is energized, this DTC is set.
INSPECTION:
STEP
1 Does ignition key being used have built-in trans-
ponder? (See Fig. 1)
2 1) Disconnect coil antenna coupler with ignition
switch turned OFF.
2) Is there continuity between coil antenna coupler
terminals A and B? (See Fig. 2)
3 Measure resistance between terminals of coil anten-
na coupler and body ground. (See Fig. 3)
Is it R (infinity) W ?
4 1) With coil antenna coupler disconnected, discon-
nect Immobilizer Control Module coupler.
2) Measure resistance between coil antenna termi-
nals of Immobilizer Control Module coupler.
(See Fig. 4)
Is it R (infinity) W ?
5 Measure resistance between terminal E127-4 of
Immobilizer Control Module coupler and body
ground.
(See Fig. 5)
Is it R (infinity) W ?
6 Measure resistance between terminal E127-3 of
Immobilizer Control Module coupler and body
ground.
(See Fig. 6)
Is it R (infinity) W ?
7 1) Connect coil antenna coupler.
2) Is there continuity between Immobilizer Control
Module coupler terminals E127-4 and E127-3?
(See Fig. 7)
ACTION YES
Go to Step 2. Replace ignition key with built-in
transponder and follow "DIAG-
NOSTIC FLOW TABLE" again.
Go to Step 3. Coil antenna open.
Go to Step 4. Coil antenna shorted to ground.
Go to Step 5. "P/B" wire shorted to "P/Bl"wire.
Go to Step 6. "P/B" wire shorted to ground.
Go to Step 7. "P/Bl" wire shorted to ground.
Go to Step 8. D "P/B" or "P/Bl" wire open.
