Select Data Analysis, A/T menu and Current Gear. Depress the brake pedal and move the
shift lever through all gears (P, R, N and D) and monitor the Current Gear. Confirm the
indicator on the cluster shows all gears. Turn the ignition OFF.

If the GDS shows:
 The correct Current Gear, the wiring currently has no open/short circuits. Go to Step 6.
 Does not show the correct Current Gear, go to Step 5.
5.
Visually check the wiring harness between the ECU and position sensor (inhibit switch) for a
damaged wire or open circuit/short circuit to ground. Check for a damaged pin or pin not fully
inserted into the connector.
 If damage is found, repair or replace the control wiring and drive the vehicle to confirm the
repair.
 If no damage or open/short circuit is found, go to Step 6.
6.
Check the grounds for the electronic
shift lever. (Refer to ETM, SD450-1).
Turn the ignition and headlights on. Use
a DVOM to check the voltage drop
between the wiring terminal and
ground.
Specification: Less than 0.2 V.
 If more than 0.2V, clean the terminal
and bolt threads and tighten the bolt.
 If less than 0.2V, go to Step 7.
