NOTE:
When measuring voltage at E127-4 and E127-3 terminals with ignition switch turned ON, be sure to turn
ignition switch ON before connecting positive probe of voltmeter to E37-1 or E37-3 terminal. If it is not
turned ON first, DTC13 (Diagnostic Trouble Code 13) may be indicated.

Resistance Check
1) Disconnect Immobilizer Control Module couplers from Immobi-
lizer Control Module with ignition switch OFF.
CAUTION:
Never touch terminals of Immobilizer Control Module
itself or connect voltmeter or ohmmeter.
2) Check resistance between each terminal of couplers discon-
nected.
CAUTION:
