PAIR
INSPECTION
Step 1
1) Remove the fuel tank. ($Page 93)
2) Turn the ignition switch OFF.
3) Check the PAIR control solenoid valve coupler for loose or
poor contacts.
If OK, then measure the PAIR control solenoid valve resis-
tance.
4) Disconnect the PAIR control solenoid valve coupler.
5) Measure the resistance between terminals.
! 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.
• Loose or poor contacts on the ECM coupler.
NO • Replace the PAIR control solenoid valve with a
new one.
6) After repairing the trouble, clear the DTC using SDS tool.
