STEP
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins and/or on-
line repair information availability.
• Is any related repair information available?
3 INSPECT TCM CONNECTOR FOR POOR
CONNECTION
• Turn ignition key to OFF.
• Check for poor connection (damaged pulled-
out terminals, corrosion, etc.).
• Are terminals okay?
4 INSPECT TR SWITCH CIRCUIT
• Connect voltmeter to TCM.
• Inspect TCM terminal voltage.
— TCM terminal 2B
• P position: B+
• Other positions and all ranges: 0V
— TCM terminal 1W
• R position: B+
• Other position and all ranges: 0V
— TCM terminal 1T
• N position: B+
• Other position and all range: 0V
— TCM terminal 1Z
• D range: B+
• Other ranges and all positions: 0V
• Are any of following terminal voltage turned on
for even a moment while shifting selector lever
slowly from P position to D range?
5 INSPECT TR SWITCH CONNECTOR FOR POOR
CONNECTION
• Turn ignition key to OFF.
• Check for poor connection (damaged pulled-
out terminals, corrosion, etc.).
• Are terminals okay?
6 INSPECT TR SWITCH CIRCUIT
• Disconnect TR switch connector.
• Connect voltmeter to TCM.
• Turn ignition key to ON (engine OFF).
• Connect harness side connector power line
and signal line using jumper wire
— P position: C and A
— R position: C and E
— N position: C and D
— D range: C and G
• Inspect if terminal voltage changes.
— 0V to B+
• Does terminal voltage change?
7 INSPECT TR SWITCH FOR OPEN CIRCUIT
• Turn ignition key to OFF.
• Inspect continuity between TR switch terminals
(part side).
— P position: C and A
— R position: C and E
— N position: C and D
— D range: C and G
• Is there continuity between TR switch terminals
(part side)?
(See K2–80 TRANSAXLE RANGE (TR) SWITCH
INSPECTION.)
8 INSPECT TR SWITCH POWER CIRCUIT FOR
OPEN CIRCUIT
• Check voltage at TR switch terminal C
(harness-side).
• Is there B+ at TR switch terminal C (harness-
side)?
