Diagnostic Procedure
Start relay power circuit inspection
1.

Remove start relay and "ST" terminal of the starter.

2.

Connect jump wire directly to switch terminals of the start relay(RLY.7) on theE/R fuse & relay box.

3.

Measure the voltage between "ST" terminal of the starter and battery (-) terminal.

■ Specification : B+

4.

Is measured voltage within the specification?

▶ Go to "Start relay control circuit inspection" procedure as below.

▶ Check for IGN2(F10) 40A fuse blown or poor connection.

▶ Check for E/R fuse & relay box.

▶ Check for open circuit between 'ST' terminal of the starter and E/R fuse & relay box.

5.

Measure the voltage between coil power supply terminal of the start relay(RLY.7) and chassis ground at IG key "START".

■ Specification : B+

6.

Is measured voltage within the specification?

▶ Check for start relay coil ground between relay and chassis ground.(M/T, LHD)

▶ Check for ignition lock switch.(M/T, RHD)

▶ Check for start relay coil ground control from TCM(A/T) at start.

▶ Check for start relay(RLY.7)

▶ Check for ignition switch, start fues(F7 7.5A) in the IPM.

▶ Check for ignition switch, start fues(F7 7.5A) in the IPM.

▶ Check for BCM start relay control in the IPM

▶ Chekck for start relay(RLY.3) in the E/R fuse & relay box.

7.

Measure the voltage between coil power supply terminal of the start relay(RLY.7) and chassis ground at IG key "START".

■ Specification : B+

8.

Is measured voltage within the specification?

▶ Check for start relay coil ground between relay and chassis ground.(M/T, LHD)

▶ Check for ignition lock switch.(M/T, RHD)

▶ Check for start relay coil ground control from TCM(A/T) at start.

▶ Check for start relay(RLY.7)

▶ Check for ignition switch, start fues(F7 7.5A) in the IPM.

▶ Check for start relay(RLY.4) coil control from TCM at start.

▶ Check for start relay(RLY.4) in the E/R fuse & relay box.

▶ Check for start relay(RLY.7) control related with SMART KEY system.
