DTC (A/T)

1. Problem verification

   - 1. Turn the vehicle to the ON mode.

   - 2. Clear the DTC with the HDS.

   - 3. Turn the vehicle to the OFF (LOCK) mode.

   Is DTC P2763 or P2764 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the sensor unit and the TCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. Open wire check (LSE, VBSOL lines)

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Disconnect the following connectors.

   TCM subharness 26P connector

   TCM 58P connector

   - 3. Check for continuity between test points 1 and 2 individually.

   Test condition	Vehicle OFF (LOCK) mode
   	TCM subharness 26P connector: disconnected
   	TCM 58P connector: disconnected
   Test point 1	TCM subharness 26P connector No. 1
   Test point 2	TCM 58P connector No. 3 - Refer to: A/T Control System Connector for Inputs and Outputs (2016 2017 2018), or A/T Control System Connector for Inputs and Outputs (2019), or A/T Control System Connector for Inputs and Outputs (2020 2021) .

   Test point 1	TCM subharness 26P connector No. 10
   Test point 2	TCM 58P connector No. 39 - Refer to: A/T Control System Connector for Inputs and Outputs (2016 2017 2018), or A/T Control System Connector for Inputs and Outputs (2019), or A/T Control System Connector for Inputs and Outputs (2020 2021) .

   Is there continuity?

   YES 

   The LSE and VBSOL wires are not open. Go to step 3.

   NO 

   Repair an open in the LSE and/or VBSOL wire between the sensor unit and the TCM.

3. Shorted wire check (LSE, VBSOL lines)

   - 1. Check for continuity between the following test points and body ground individually.

   Test condition	Vehicle OFF (LOCK) mode
   	TCM subharness 26P connector: disconnected
   	TCM 58P connector: disconnected

   Connector	Terminal
   TCM 58P connector - Refer to: A/T Control System Connector for Inputs and Outputs (2016 2017 2018), or A/T Control System Connector for Inputs and Outputs (2019), or A/T Control System Connector for Inputs and Outputs (2020 2021) .	No. 3
   	No. 39

   Is there continuity?

   YES 

   Repair a short to ground in the LSE and/or VBSOL wire between the sensor unit and the TCM.

   NO 

   The LSE and VBSOL wires are OK. Replace the hydraulic control unit .
