3 | Is the coil antenna connector securely connected to the coil antenna? | Yes | Go to the next step.
No | Connect the coil antenna connector securely. Return to Step 1.
4 | Does the security light flush? | Yes | Go to the next step.
No | Inspect the following: • Wiring harnesses and connectors from keyless control module terminal 3W and instrument cluster terminal 1W • Wiring harness and connectors from keyless control module terminal 3X and instrument cluster terminal 1X • Instrument cluster (See INSTRUMENT CLUSTER INSPECTION.) Repair or replace the malfunctioning part according to the inspection results.
5 | Retrieve the DTC for immobilizer system. (See DTC INSPECTION [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND START SYSTEM)].) Is there any DTC present? | Yes | Go to the appropriate DTC inspection. (See DTC TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].) (See DTC TABLE [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND START SYSTEM)].)
No | Go to the next step.
6 | Inspect for the following wiring harnesses and connectors: • With advanced keyless entry and start system: ― Between coil antenna terminal A and keyless control module terminal 3V ― Between coil antenna terminal B and keyless control module terminal 3U • Without advanced keyless entry and start system: ― Between coil antenna terminal A and instrument cluster terminal 1E ― Between coil antenna terminal B and instrument cluster terminal 1G Is there any malfunction? | Yes | Repair or replace suspected wiring harness and connector.
No | With advanced keyless entry and start system: • Go to the next step. Without advanced keyless entry and start system: • Go to the Step 8.
7 | Inspect the following wiring harnesses and connectors for an open or short circuit: • Between keyless control module terminal 3W and instrument cluster terminal 1W • Between keyless control module terminal 3X and instrument cluster terminal 1X Is there any malfunction? | Yes | Repair or replace suspected wiring harness and connector.
No | Go to the next step.
8 | Inspect for the following wiring harnesses and connectors: • Between PCM terminal 1AL and instrument cluster terminal 1W • Between PCM terminal 1AH and instrument cluster terminal 1X Is there any malfunction? | Yes | Repair or replace suspected wiring harness and connector.
No | Go to the next step.
9 | Inspect the following: • Battery connection • Battery condition (See BATTERY INSPECTION [MZI-3.7].) • Fuses (See NO.1 MELTING OF MAIN OR OTHER FUSES [MZI-3.7].) • Transmission in P or N position Are all items normal? | Yes | Go to the next step.
No | Repair or replace the malfunctioning part according to the inspection results. Repeat Step 9.
10 | Turn ignition switch to the ON position. (Engine off) Access the PCM PID TR using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7].) Is the TR PID indicated P/N when selecting P or N position? | Yes | Go to the next step.
No | Inspect the following: • TR switch is adjusted properly. • Open or short circuit between TR switch and TCM Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
11 | Is clicking sound heard from starter relay when the ignition switch is turned to START position? | Yes | Go to Step 14.
No | Go to the next step.
12 | Inspect the starter relay and following harnesses: (See RELAY INSPECTION.) • Between starter relay and PCM • Between starter relay and ignition switch Are they normal? | Yes | Go to the next step.
No | Repair or replace the malfunctioning part according to the inspection results, then go to Step 11.
13 | Inspect the ignition switch and related harnesses. (See IGNITION SWITCH INSPECTION.) Are they normal? | Yes | Go to the next step.
No | Repair or replace the malfunctioning part according to the inspection results, then go to Step 11.
14 | Inspect the following harnesses: • Between starter relay and Battery • Between starter relay and Starter Are they normal? | Yes | Go to the next step.
No | Repair or replace the malfunctioning part according to the inspection results, then go to the next step.
15 | Inspect the starting system. (See STARTER INSPECTION [MZI-3.7].) Is the starting system normal? | Yes | Go to the next step.
No | Repair or replace the malfunctioning part according to the inspection results.
16 | Inspect for seized/hydro locked engine or flywheel. Is the engine seized or hydro locked? | Yes | Repair or replace the malfunctioning part according to the inspection results.
No | Go to the next step.
17 | Retrieve any PCM continuous memory DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7].) Are there any continuous memory DTCs displayed? | Yes | DTC is displayed: • Go to the appropriate DTC inspection. (See DTC TABLE [MZI-3.7].) Communication error message is displayed: Inspect for the following: • Main relay No.1 is stuck open. • Poor connection of vehicle body ground • Open circuit in wiring harness between main relay No.1 and PCM terminal 1BK or 1BP • Open circuit in wiring harness between main relay No.1 and PCM terminal 1AZ • Open or short circuit in wiring harness between DLC-2 and PCM terminals 1AH or 1AL • Open or poor ground circuit (PCM terminal 1B, 1E, 1J) Repair or replace the malfunctioning part according to the inspection results.
No | No DTC is displayed: • Go to the next step.
18 | Retrieve any KOEO DTCs using M-MDS. (See KOEO/KOER SELF TEST [MZI-3.7].) (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7].) Are there DTCs displayed during KOEO inspection? | Yes | DTC is displayed: • Go to the appropriate DTC inspection. (See DTC TABLE [MZI-3.7].)
No | No DTC is displayed: • Go to the next step.
19 | • Verify test results. ― If normal, return to diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX [MZI-3.7].) ― If malfunction remains, inspect related Service Information and perform repair or diagnosis. • If vehicle is repaired, troubleshooting completed. • If vehicle is not repaired or additional diagnostic information is not available, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].)
