Diagnostic Procedure

Step | Inspection | Action
--- | --- | ---
1 | VERIFY PCM DTCs • Retrieve the PCM DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7].) • Are any DTCs displayed? | Yes | Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [MZI-3.7].)
No | Go to the next step.
2 | INSPECT BATTERY • Inspect the battery. (See BATTERY INSPECTION [MZI-3.7].) • Is the battery normal? | Yes | Go to the next step.
No | Replace the battery, then go to Step 4. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].)
3 | INSPECT GENERATOR • Inspect the generator. (See GENERATOR INSPECTION [MZI-3.7].) • Is the generator normal? | Yes | Go to the next step.
No | Replace the generator, then go to the next step. (See GENERATOR REMOVAL/INSTALLATION [MZI-3.7].)
4 | VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the BSM control module using the M-MDS. (See CLEARING DTC [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].) • Switch the ignition ON (engine off or on) and wait for 10 s or more. • Retrieve the BSM control module DTCs using the M-MDS. (See DTC INSPECTION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].) • Is the same DTC displayed? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the BSM control module. (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].) Go to the next step.
No | Go to the next step.
5 | VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed? | Yes | Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 10-PIN TYPE].)
No | DTC troubleshooting completed.
