DTC P1564 ICC STEERING SWITCH
Revision: 2006 January2006 M35/M45
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureNBS005MC
1. CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Loosen and retighten two ground screws on the body.
Refer to EC-885, "
Ground Inspection" .

DTC P0605 ECM" .
If DTC P1715 is displayed with DTC P0335, first perform the trouble diagnosis for DTC P0335.
Refer to EC-1099, "
DTC P0335 CKP SENSOR (POS)" .
If DTC P1715 is displayed with DTC P0340, first perform the trouble diagnosis for DTC P0340.
Refer to EC-1106, "
DTC P0340 CAMSHAFT POSITION (CMP) SENSOR (PHASE)" .
The MIL will not lights up for this diagnosis.
Diagnostic ProcedureNBS005ND
