DTC P272C  : Park Pawl Motor Control Circuit

DTC (Gear)

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.

   -4. Turn the vehicle to the ON mode, and wait for at least 10 seconds.

   -5. Check for Pending or Confirmed DTCs with the HDS.

   Is DTC P272C 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 park pawl actuator and the park pawl actuator driver unit. 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. Shorted wire check (MAU/P-ACT MTR U line, MAV/P-ACT MTR V line, MAW/P-ACT MTR W line to power)

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

   -2. Disconnect the following connectors.

   Park pawl actuator 10P connector

   Park pawl actuator driver unit 26P connector

   -3. Measure the voltage between the following test points and body ground individually.

   Test condition	Vehicle OFF (LOCK) mode
   	Park pawl actuator 10P connector: disconnected
   	Park pawl actuator driver unit 26P connector: disconnected

   Connector	Terminal
   Park pawl actuator 10P connector (female terminals):	No. 1
   	No. 6
   	No. 7

   Is there voltage?

   YES 

   Repair a short to power in the MAU/P-ACT MTR U wire, the MAV/P-ACT MTR V wire, and/or the MAW/P-ACT MTR W wire between the park pawl actuator and the park pawl actuator driver unit.

   NO 

   The MAU/P-ACT MTR U wire, the MAV/P-ACT MTR V wire, and/or the MAW/P-ACT MTR W wire are not shorted to power. Go to step 3.

3. Open wire check (GND line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	Park pawl actuator 10P connector: disconnected
   	Park pawl actuator driver unit 26P connector: disconnected

   Connector	Terminal
   Park pawl actuator driver unit 26P connector	No. 2
   	No. 3
   	No. 17
   	No. 18

   Is there continuity?

   YES 

   The GND wire is OK. Go to step 4.

   NO 

   Repair an open in the GND wire between the park pawl actuator driver unit and ground (G305), or repair poor ground (G305).

4. Park pawl actuator driver unit check

   -1. Substitute a known-good park pawl actuator driver unit .

   -2. Reconnect the following connectors.

   Park pawl actuator 10P connector

   Park pawl actuator driver unit 26P connector

   -3. Turn the vehicle to the ON mode.

   -4. Update the park pawl actuator driver unit .

   

   Do not turn the vehicle to the OFF (LOCK) mode. Turning the vehicle to the OFF (LOCK) mode during an update can damage the park pawl actuator driver unit.

   -5. Clear the DTC with the HDS.

   -6. Turn the vehicle to the OFF (LOCK) mode.

   -7. Turn the vehicle to the ON mode, and wait for at least 10 seconds.

   -8. Check for Pending or Confirmed DTCs with the HDS.
