Diagnostic Procedure

CHECK EGRC SOLENOID VALVE
With CONSULT-II
1. Turn ignition switch ON.
2. Turn EGRC solenoid valve "ON" and "OFF" in "ACTIVE TEST" mode with CONSULT-II and check operating sound.

Without CONSULT-II
1. Start engine and rev engine up to 3,000 RPM quickly.
2. When disconnecting and reconnecting the EGRC solenoid valve harness connector, make sure that the EGRC solenoid valve makes operating sound. (The DTC or the 1st trip DTC for the EGRC solenoid valve will be displayed, however, ignore it.)
OK or NG
1. OK (With CONSULT-II): GO TO 6.
2. OK (Without CONSULT-II): GO TO 7.
3. NG: GO TO 2
CHECK POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect EGRC solenoid valve harness connector. See Fig 2.
3. Turn ignition switch ON.
4. Check voltage between terminal 2 and ground with CONSULT-II or tester.

  OK or NG
1. OK: GO TO 4.
2. NG: GO TO 3.
DETECT MALFUNCTIONING PART
Check the following.
- Harness connectors E43, M65
- Harness connectors M59, F27
- Fuse block (J/B) connector E49
- 10A fuse
- Harness for open or short between EGRC solenoid valve and fuse
  1. Repair harness or connectors.
CHECK OUTPUT SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminal 103 and terminal 1.
  Refer to WIRING DIAGRAM .
  
  Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
1. OK (With CONSULT-II): GO TO 6.
2. OK (Without CONSULT-II): GO TO 7.
3. NG: GO TO 5
DETECT MALFUNCTIONING PART
Check the harness for open or short between EGRC solenoid valve and ECM.
1. Repair open circuit or short to ground or short to power in harness or connectors.
CHECK EGRC-SOLENOID VALVE
1. Perform "EGRC SOLENOID VALVE" in "ACTIVE TEST" mode.
2. Check air passage continuity and operation delay time under the following conditions.
