DTC Troubleshooting: P0910 (162-4)

DTC P0910:
 Select Actuator Motor System Malfunction
  1. Turn the ignition switch to ON (II).
  1. Clear the DTCs with the HDS.
  1. Check for DTCs with the HDS.
Is DTC P0910 indicated?
YES -
Go to Step 5 .
NO -
Intermittent failure, the system is OK at this time.■
  1. Turn the ignition switch to LOCK (0).
  1. Reconnect the 6P connectors to the transmission shift change actuator.
  1. Turn the ignition switch to ON (II).
  1. Change the shift lever from D to N, then from N to D, and check the select actuator rod (A) operation.
Does the select actuator rod move smoothly?
YES -
Repair the transmission internal failure.■
NO -
Go to Step 10 .
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the select actuator motor 6P connector.

  1. Change the shift lever from D to N, then from N to D, and measure voltage between select actuator motor 6P connector terminals No. 1 and No. 6.
Does the battery voltage change from positive (or negative) to negative (or positive) depending by the shift lever operation?
YES -
NO -
Go to Step 13 .

  1. Change the shift lever from D to N, then from N to D, and measure voltage between select actuator motor 6P connector terminal No. 1 and body ground.
Does the voltage change from 0 V (or battery voltage) to battery voltage (or 0 V) depending by the shift lever operation?
YES -
Go to Step 14 .
NO -
Repair an open in the wire between the TCM and the transmission shift change actuator.■

  1. Change the shift lever from D to N, then from N to D, and measure voltage between select actuator motor 6P connector terminal No. 6 and body ground.
Does the voltage change from 0 V (or battery voltage) to battery voltage (or 0 V) depending by the shift lever operation?
YES -
Remove the clutch actuator assembly, and check for change actuator subharness A. If the wire harness is OK, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
NO -
Repair an open in the wire between the TCM and the transmission shift change actuator.■
