Turn ON the ignition switch, and check by shifting to each range.
|
|
- "P" range: Terminal No. 6 to body earth → System voltage
- "R" range: Terminal No. 7 to body earth → System voltage
- "N" range: Terminal No. 21 to body earth → System voltage
- "D" range: Terminal No. 8 to body earth → System voltage

Q.
Is the check result normal?
|
|
Turn OFF the ignition switch, and check the following items.

|
|
Check for continuity between B-121 inhibitor switch terminals and C-138 A/T-ECU terminals.
|
|
- Between B-121 terminal No. 2 and C-138 terminal No. 6: At the "P" range, continuity exists.
- Between B-121 terminal No. 9 and C-138 terminal No. 7: At the "R" range, continuity exists.
- Between B-121 terminal No. 8 and C-138 terminal No. 21: At the "N" range, continuity exists.
- Between B-121 terminal No. 5 and C-138 terminal No. 8: At the "D" range, continuity exists.
