Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY RELATED PENDING CODE OR STORED DTCs FOR ALL OF VEHICLE MODULE • Turn the ignition switch off then to the ON position (Engine off). • Verify related pending code or stored DTCs. • Is other DTCs present? | Yes | Go to the appropriate DTC troubleshooting. (See DTC TABLE [MZI-3.7].)
No | Go to the next step.
4 | INSPECT THROTTLE BODY AND PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the throttle body and PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are there any malfunction? | Yes | Repair or replace suspected part, then go to Step 7.
No | Go to the next step.
5 | INSPECT FOR PROPER TACM+ WIRING IN WIRING HARNESS CONNECTOR • Throttle body and PCM connectors are disconnected. • Measure the resistance between throttle body terminal B and PCM terminal 2BR. • Is the resistance less than 5 ohms? | Yes | Go to the next step.
No | Repair TACM+ circuit for an open circuit, then go to Step 7.
6 | INSPECT FOR PROPER TACM- WIRING IN HARNESS CONNECTOR • Throttle body and PCM connectors are disconnected. • Measure the resistance between throttle body terminal A and PCM terminal 2BO. • Is the resistance less than 5 ohms? | Yes | Go to the next step.
No | Repair TACM- circuit for an open circuit, then go to the next step.
7 | VERIFY TROUBLESHOOTING OF DTC P2101:00 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Start the engine. • Clear DTC from PCM memory using M-MDS. • Perform the KOEO or KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is same DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
