DTC P0616: Starter Relay "A" Circuit Low: Notes
1. -
DTC detecting condition:
Immediately at fault recognition
Wiring diagram:
Engine Electrical System Ref. to WIRING SYSTEM>ENGINE ELECTRICAL SYSTEM .
- Model without push button start
CAUTION:
Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>GENERAL PRESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD
.
NOTE:
After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE
.
- CHECK HARNESS BETWEEN ECM AND M/B (STARTER RELAY) (OPEN)
.
- Turn the ignition switch to OFF.
- Disconnect the connector from ECM.
- Remove the starter relay.
- Measure the resistance of harness between ECM connector and M/B (starter relay) terminal No. 3.
Connector and terminal
(B134) No. 27 - No. 3:
Is the resistance less than 1 Ω?
Yes : Go to 2 .
No : Repair the open circuit of harness between ECM connector and M/B (starter relay).
- CHECK HARNESS BETWEEN ECM AND M/B (STARTER RELAY) (SHORT TO GROUND)
.
- Disconnect the connector from starter motor.
- Measure the resistance between the ECM connector and engine ground.
Connector and terminal
(B134) No. 27 - Engine ground:
Is the resistance 1 MΩ or more?
Yes : Repair the poor contact of ECM connector.
No : Repair the short circuit to ground in harness between ECM connector and M/B (starter relay).
