Mariner 2WD L4-2.5L Hybrid (2010)
Control Module: Testing and Inspection
TRANSAXLE CONTROL MODULE (TCM) REPROGRAMMING
WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to
depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its
components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage
components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious
personal injury or death.
Description
NOTE: After the TCM is successfully reprogrammed, clear the continuous diagnostic trouble codes (DTCs) in the powertrain control module (PCM)
and the TCM that may have been stored during reprogramming.
Changes made to the strategy or calibration may require TCM reprogramming. Refer to the Module Programming instructions on the scan tool.
Making Changes To The TCM Calibration
If the TCM does not complete the reflash after 2 consecutive attempts, follow the instructions listed below:
1. If the TCM reprogramming aborts during the procedure:
-
Reprogram the TCM again.
-
After the TCM reprogramming is successfully completed, clear the continuous DTCs in the PCM and the TCM.
2. If the TCM reprogramming aborts immediately after the start:
-
Turn the ignition OFF.
-
Disconnect the PCM body/cowl connector, and leave it disconnected.
-
Turn the ignition ON.
-
Start the TCM reprogramming.
-
After the TCM reprogramming is successfully completed, turn the ignition OFF and connect the PCM body/cowl connector.
-
Clear any PCM and TCM DTCs that may have been stored during reprogramming.
