STEP
3 VERIFY CURRENT INPUT SIGNAL STATUS-IS
CONCERN INTERMITTENT OR CONSTANT?
• Connect volt meter to TCM.
• Turn ignition key to ON (engine OFF).
• Inspect TCM terminal voltages.
(See K2–90 TCM
— TCM terminal 2B
• P position: B+
• Other positions and all ranges: 0V
— TCM terminal 1W
• R position: B+
• Other positions and all ranges: 0V
— TCM terminal 1T
— N position: B+
— Other positions and all ranges: 0V
— TCM terminal 1Z
• D range: B+
• Other ranges and all positions: 0V
• Are two or more of following terminal voltage at
the same time when shifting selector lever from
P position to D range?
4 INSPECT TR SWITCH CONNECTOR
• Turn ignition key OFF.
• Disconnect TR switch connector.
• Inspect bent terminals of pins using mirror.
• Are TR switch terminals okay?
5 INSPECT TR SWITCH CIRCUIT MALFUNCTION
• Connect voltmeter to TCM.
• Turn ignition key to ON (engine OFF).
• Does TCM terminal voltage change from B+ to
0V when TR switch connector is disconnected?
6 INSPECT TR SWITCH CONTINUITY
• Turn ignition key to OFF.
• Disconnect TR switch connector.
• Inspect TR switch for continuity in positions/
ranges failed in Step 4.
• Is there continuity between TR switch terminals
(part side)?
(See K2–80 TRANSAXLE RANGE (TR) SWITCH
INSPECTION.)
7 INSPECT TR SWITCH CIRCUIT FOR SHORT TO
POWER
• Turn ignition key to ON (engine OFF).
• Measure voltage at TR switch terminal A, E, D,
G, I, and F (harness-side).
• Is there 0 V at TR switch harness side
connector?
8 VERIFY TROUBLESHOOTING OF DTC P0705
COMPLETED
• Make sure to reconnect all disconnected
connectors.
• Clear DTC from memory using WDS or
equivalent.
• Turn ignition key to on (engine off).
• Drive vehicle in each range (P, R, N, and D) for
5 seconds or more.
• Is same DTC present?
9 VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
(See K2–124 AFTER REPAIR
• Is there any DTC present?
