NOTE:
When measuring voltage at G08-1 and G08-3 terminals with ignition switch turned ON, be sure to turn igni-
tion switch ON before connecting positive probe of voltmeter to G08-1 or G08-3 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:
Do not touch terminals of Immobilizer Control Module it-
self or connect voltmeter or ohmmeter.
2) Check resistance between each terminal of couplers discon-
nected.
CAUTION:
