―  Related wiring harness malfunction

•  Brake switch signal malfunction

―  Brake switch malfunction

―  Related connector or terminals malfunction

―  Related wiring harness malfunction

―  Brake pedal malfunction (increase in play due to joint pin wear)

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	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.
1		No	Go to the next step.
2	VERIFY VEHICLE USE CONDITION • Verify the vehicle use condition. ― The floor mat is doubled over ― The floor mat is spread against the accelerator pedal ― The accelerator and brake pedals are being depressed simultaneously • Are any of the conditions above applicable to vehicle use condition?	Yes	There is a malfunction in a related floor mat • Explain to the customer that the floor mat may prevent the accelerator pedal from springing back after release, then go to Step 10. There is a malfunction in the pedal operation • Give the customer advice on how to depress the accelerator and brake pedals while driving the vehicle, then go to Step 10.
2		No	Go to the next step.
3	INSPECT APP SENSOR • Is the condition of the accelerator pedal one of the following? ― Accelerator pedal sticking has occurred when operated ― There is evidence of accelerator pedal disassembly	Yes	Replace the accelerator pedal, then go to Step 10. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [MZI-3.7].)
3		No	Go to the next step.
4	VERIFY CURRENT INPUT SIGNAL STATUS OF APP SENSOR • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7 (PCM CONNECTOR (3 TYPES))].) ― IVS ― APP1 ― APP2 • Is the value for PID IVS Idle when the accelerator pedal is not depressed? • Do the values for PIDs APP1 and APP2 change when the accelerator pedal is continually depressed?	Yes	Go to the next step.
4		No	Go to Step 6.
5	INSPECT APP SENSOR RELATED WIRING HARNESS AND CONNECTOR • Inspect the wiring harness related to the APP sensor for connector disconnection, short circuit, and poor contact. • Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results, then go to Step 10.
5		No	APP sensor malfunction. • Replace the accelerator pedal, then go to Step 10. (See ACCELERATOR PEDAL REMOVAL/INSTALLATION [MZI-3.7].)
6	VERIFY CURRENT INPUT SIGNAL STATUS OF BRAKE SWITCH • Access the following PIDs using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST [MZI-3.7 (PCM CONNECTOR (3 TYPES))].) ― BOO ― BPA • Are all PIDs normal?	Yes	Go to Step 9.
6		No	Go to the next step.
7	INSPECT BRAKE SWITCH • Inspect the brake switch. (See BRAKE SWITCH INSPECTION.) • Is there any malfunction?	Yes	Replace the brake switch, then go to Step 10. (See BRAKE PEDAL REMOVAL/INSTALLATION [L.H.D.].) (See BRAKE PEDAL REMOVAL/INSTALLATION [R.H.D.].)
7		No	Go to the next step.
8	INSPECT BRAKE PEDAL PLAY AMOUNT • Inspect the brake pedal play amount. (See BRAKE PEDAL INSPECTION [L.H.D.].) (See BRAKE PEDAL INSPECTION [R.H.D.].) • Is the amount of brake pedal play normal?	Yes	Inspect the wiring harness related to the brake switch for connector disconnection, short circuit, and poor contact. • If there is any malfunction: ― Repair or replace the malfunctioning part according to the inspection results, then go to Step 10.
8		No	Repair or replace the malfunctioning part according to the inspection results, then go to Step 10.
9	VERIFY IF A DTC RELATED TO DRIVE-BY-WIRE CONTROL IS DETECTED • Perform the KOER self test. (See KOEO/KOER SELF TEST [MZI-3.7 (PCM CONNECTOR (3 TYPES))].) • Is a DTC related to the drive-by-wire control present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7 (PCM CONNECTOR (3 TYPES))].)
9		No	Go to the next step.
10	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZI-3.7 (PCM CONNECTOR (3 TYPES))].) • Perform the KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7 (PCM CONNECTOR (3 TYPES))].) • Is the 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.
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7 (PCM CONNECTOR (3 TYPES))].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7 (PCM CONNECTOR (3 TYPES))].)
11		No	Troubleshooting completed.
