Checkpoints: 1. Check Battery Voltage at key on (min 11 V) Trouble Shooting Steps: Sr. No. Steps Specifications Step 1 Check the battery voltage with the ignition switch on. If the voltage is too low then recharge the battery Minimum 11 V Step 2 Check whether the battery terminals are connected properly and they are tight. If not proper do the necessary repair Proper connection Step 3 Check ECU connection: 1] Key off 2] Remove the ECU 3] Connect ECU connector Properly 4] Key on and Read the faults Step 4 Check the charging circuit. In case of any problems in charging do the necessary repair Step 5 If problem still persists; Replace the ECU. Circuit Description: The battery supplies electricity to ECM even when the ignition switch is OFF. This electricity allows ECM to store data such as DTC history, freeze frame data, fuel trim values and other data. If the battery voltage falls out of range, ECM will conclude that there is a fault in the power supply circuit. Circuit Schematic Diagram: Component location and image:
