4. Diagnostic
procedures:
Note: Before carrying out this diagnosis step, observe the data list on fault diagnosis tester and analyze the
accuracy of the data, as these will help with quick diagnosis.
1
Read the fault code again after clearing away the fault code to check if fault codes, except DTC
P0985 and P0986 exist in the control system.
A. Connect fault diagnosis tester to the datalink connector.
B. Rotated ignition switch to ON position
C. Switch on fault diagnostic device power supply
D. Clear DTC code.
E. Reset reading fault code, and check if DTCs meet setting condition of fault code in current

Detect S5electromagnetic valve resistance
A. Turn the ignition switch to the OFF position.
B. Disconnect the harness connector J-4 of the
electromagnetic valve.
C. Measure the resistance between Terminals 2 and
1 of the electromagnetic valve harness connector
J-4.
Standard resistant value :4.11Ω-4.17Ω

A. rotated ignition switch to OFF position.
B. Disconnect the harness connector J-4 of the
electromagnetic valve.
C. Measure the resistance between Terminal No.2 of
the electromagnetic valve harness connector J-4
and Terminal 5 of the automatic control module
J-1.
D. Measure the resistance between Terminal No.1 of
the electromagnetic valve harness connector J-4
and Terminal 7 of the automatic control module
J-1.
E. Turn the ignition switch to the ON position.
F. Measure voltage of electromagnetic valve
harness connector J-4No.2 terminal and reliable
