DESCRIPTION

Some vehicles may experience the check engine light and automatic transaxle warning light ON with one or more of these DTCs stored in the TCM memory (P0842, P0847, P0872, P0877, P0780).

• P0842:00 - Oil pressure switch No. 1 (oil pressure switch B) stuck on

• P0847:00 - Oil pressure switch No. 2 (oil pressure switch A) stuck on

• P0872:00 - Oil pressure switch No. 3 (oil pressure switch A) stuck on

• P0877:00 - Oil pressure switch No. 4 (oil pressure switch B) stuck on

• P0780:00 - Gear shifting malfunction

This is caused by the oil pressure switch A and/or B at the control valve body temporarily or permanently getting stuck due to contamination entering the passage. To correct the problem, some mass production changes have been implemented to reduce contamination and improve the DTC diagnostic logic.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Verify customer concern.

2. Check for DTCs.

• If any of the DTCs (P0842, P0847, P0872, P0877, P0780) is stored in TCM memory, go to step 3.

• If any other DTCs are present or no DTCs are present, perform Workshop Manual troubleshooting.

2013-2016 CX-5 JM3KE******100001 - 599999 (except Mexico spec)

NOTE:

• If the concern has occurred with older TCM file, parts replacement is not necessary.

• If the concern has occurred with new TCM file, proceed to Parts Replacement.

• If the new TCM file for the vehicle is TBD, proceed to Parts Replacement.

TCM Reprogramming

1. Reboot the IDS to clear memory before reprogramming.

2. Using IDS 95.04 or later software, reprogram the TCM to the latest calibration (refer to “Calibration Information” table) by following the “Module Reprogramming” procedure.

NOTE:

• Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for TCM reprogramming.

• It is not necessary to remove any fuses or relays during TCM reprogramming when the IDS screen prompts you to do so. You may accidentally stop power to one of the TCM terminals and cause the TCM to be blanked, or you may receive error messages during the IDS reprogramming procedure.

• IDS shows the calibration part numbers after programming the TCM.

• Please be aware that TCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of IDS software, and additional revisions made to those calibrations for service related concerns.

• When reprogramming a TCM, IDS will always display the “latest” calibration P/N available for that vehicle. If any calibration has been revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.

•

When performing this procedure, we recommend using the “Power Supply” mode in the

Battery Management System to keep the vehicle battery up to capacity. If a different charger is used, make sure it does not exceed 20 AMPS. If it exceeds 20 AMPS, it could damage the VCM.

3. After performing the TCM reprogramming procedure, verify the repair by starting the engine and making sure there is no Check Engine Light or abnormal warning lights present.

NOTE:

• If any DTCs should remain after performing DTC erase, diagnose the DTCs using MS3 online instructions or Workshop Manual section 01-02.

• After TCM reprogramming, it is no longer necessary to road test the vehicle to “relearn” KAM

(Keep Alive Memory).

4. Perform “Initial Learning” according to the instructions on MS3 online or the Workshop Manual (section 05-

17 INITIAL LEARNING [FW6AEL, FWAX-EL])
