DTC P0882:00 [TCM (ET6A-EL, ET6AX-EL) (E)]

id0502q98231r2

Outline

System malfunction location	TCM power supply voltage low
Detection condition	• Under the following conditions, the TCM power supply voltage is 8—10.5 V or less (varies with ATF temperature): ― 5 s or more has elapsed or battery voltage exceeds 11 V or more for 0.2 s since engine speed increases −200 rpm or more of target idle speed. ― Selector lever position is D or R position.
Fail-safe	• Set to emergency mode. • Inhibits learning control. • Inhibits manual mode. • Inhibits neutral idle control. • Inhibits i-stop control. • Inhibits AAS.
Possible cause	• PCM DTC is stored. • Looseness of battery terminals • Battery malfunction • Generator malfunction (without Mazda M Hybrid) • Integrated starter generator (ISG) malfunction (with Mazda M Hybrid) • TCM connector or terminals malfunction • TCM power supply circuit malfunction ― Short to ground in TCM power supply circuit ― F22 15 A fuse malfunction ― Open circuit in TCM power supply circuit • Open circuit in TCM ground circuit

Diagnostic procedure

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION • Record the freeze frame data/snapshot data. Note • Recording can be facilitated using the screen capture of the PC function.	—	Go to the next step.
2	VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY • Verify related Service Bulletins, on-line repair information, or Service Information availability. • Is any related Information available?	Yes	Perform repair or diagnosis according to the available information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY PCM DTC • Perform the PCM DTC inspection using the M-MDS. (See DTC INSPECTION.) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G (E))].) (See DTC TABLE [PCM (SKYACTIV-X)].) (See DTC TABLE [PCM (SKYACTIV-D)].)
3		No	Go to the next step.
4	INSPECT BATTERY CONNECTOR FOR MALFUNCTION • Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) • Are the connector and terminal normal?	Yes	Go to the next step.
4		No	Repair or replace the malfunctioning location and perform the repair completion verification.
5	INSPECT BATTERY FOR MALFUNCTION • Inspect the applicable part. (See BATTERY INSPECTION [(E)].) • Is the part normal?	Yes	Go to the next step.
5		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See BATTERY RECHARGING [(E)].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
6	INSPECT GENERATOR (WITHOUT Mazda M Hybrid)/INTEGRATED STARTER GENERATOR (ISG) (WITH Mazda M Hybrid) FOR MALFUNCTION • Inspect the applicable part. (See GENERATOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))].) (See INTEGRATED STARTER GENERATOR (ISG) INSPECTION.) (See GENERATOR INSPECTION [SKYACTIV-D 1.8].) • Is the part normal?	Yes	Go to the next step.
6		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))].) (See INTEGRATED STARTER GENERATOR (ISG) REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) (See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
7	INSPECT TCM CONNECTOR AND TERMINALS • Switch the ignition off. • Disconnect the TCM connector. • Visually inspect the TCM connector and terminals. • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to repair completion verification.
7		No	Go to the next step.
8	INSPECT TCM POWER SUPPLY CIRCUIT • Always reconnect all disconnected connectors. • Access the PID VPWR using the M-MDS. (See PID/DATA MONITOR INSPECTION.) • Is the PID value B+?	Yes	Go to the next step.
8		No	Inspect the F22 15 A fuse. • If the fuse is blown: ― Refer to the wiring diagram and verify whether or not there is a common connector between F22 15 A fuse and TCM terminal A. If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to ground. • Replace the fuse. • If the fuse is deteriorated: ― Replace the malfunctioning fuse. • If the fuse is normal: ― Refer to the wiring diagram and verify whether or not there is a common connector between battery positive terminal and TCM terminal A. If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to the next step.
Repair completion verification	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC using the M-MDS. (See CLEARING DTC.) • Perform the following procedure to ensure that the DTC has been resolved: 1. Drive the vehicle for 5 s or more under the following condition: • Selector lever position: D or R position • Perform the DTC inspection using the M-MDS. (See DTC INSPECTION.) • Are any DTCs present?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification		No	DTC troubleshooting completed.
