"C49" (P1656) PAIR CONTROL SOLENOID VALVE CIRCUIT MALFUNCTION

DETECTED CONDITION
PAIR control solenoid valve voltage is not input to
ECM.

PAIR
INSPECTION
Step 1
1) Turn the ignition switch OFF.
2) Remove the lower leg shield. (#AN650K3 9-10)
3) Check the PAIR control solenoid valve coupler 1 for loose or
poor contacts.
If OK, then measure the PAIR control solenoid valve resis-
tance.
4) Remove the PAIR control solenoid valve coupler.
5) Measure the resistance between terminals (valve side).
$ PAIR control solenoid valve resistance:
! 09900-25008: Multi-circuit tester set
) Tester knob indication: Resistance (Ω)
Is the resistance OK?
YES Go to Step 2.
Replace the PAIR control solenoid valve with a
NO
new one.
6) After repairing the trouble, clear the DTC using SDS tool.
(Refer to the SDS operation manual for further details.)
