DTC Troubleshooting: P2785 (163-1)

DTC P2785:

Clutch Actuator Temperature Too High

NOTE: DTC P2785 is stored when the clutch motor is protection mode. This can be caused due to frequent UP/DOWN operation. In this case, it is not a malfunction.

Check whether the driver changed gears excessively while driving.

Did the driver change gears excessively while driving?

YES	-	Not failure, just a rise of the clutch actuator temperature due to excessive gear changes.■
NO	-	Go to Step 2 .

Check the CLUTCH ACTUATOR TEMPERATURE and the TRANSMISSION SHIFT CHANGE ACTUATOR TEMPERATURE in the DATA LIST with the HDS.

Is the clutch actuator temperature about 195 °C (383 °F) or more, or the transmission shift change actuator temperature about 118 °C (244 °F) or more?

YES	-	Go to Step 3 .
NO	-	Go to Step 6 .

Turn the ignition switch to LOCK (0).

In order to cool the system, wait for at least 1 hour.

Check the CLUTCH ACTUATOR TEMPERATURE and the TRANSMISSION SHIFT CHANGE ACTUATOR TEMPERATURE in the DATA LIST with the HDS.

Is the clutch actuator temperature about 195 °C (383 °F) or more, or the transmission shift change actuator temperature about 118 °C (244 °F) or more?

YES	-	Update the TCM if it does not have the latest software, or substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM. ■
NO	-	Go to Step 6 .

Test-drive the vehicle with changing gears frequently for at least 15 minutes.

Check the CLUTCH ACTUATOR TEMPERATURE and the TRANSMISSION SHIFT CHANGE ACTUATOR TEMPERATURE in the DATA LIST with the HDS.

Is the clutch actuator temperature about 195 °C (383 °F) or more, or the transmission shift change actuator temperature about 118 °C (244 °F) or more?

YES	-	Go to Step 8 .
NO	-	Intermittent failure, the system is OK at this time.■

Check the release fork moves smoothly.

Does the release fork move smoothly?

YES	-	Replace the TCM. ■
NO	-	Replace the release bearing. ■
