--- | ---
DETECTION CONDITION | • If no range signal is input from the TR switch for 100 s or more, the TCM determines that there is a malfunction.

• PENDING CODE is available.
• FREEZE FRAME DATA is available.
• The HOLD indicator light flashes.
• The DTC is stored in the TCM memory.
POSSIBLE CAUSE | • TR switch malfunction • TR switch misadjustment • Short to ground in wiring harness between TR switch terminal A and TCM terminal 2B • Short to ground in wiring harness between TR switch terminal E and TCM terminal 1W • Short to ground in wiring harness between TR switch terminal D and TCM terminal 1T
• Short to ground in wiring harness between TR switch terminal G and TCM terminal 1Z
• Short to ground in wiring harness between TR switch terminal I and TCM terminal 1AA
• Short to ground in wiring harness between TR switch terminal F and TCM terminal 2C
• Open circuit in wiring harness between TR switch terminal A and TCM terminal 2B
• Open circuit in wiring harness between TR switch terminal E and TCM terminal 1W
• Open circuit in wiring harness between TR switch terminal D and TCM terminal 1T
• Open circuit in wiring harness between TR switch terminal G and TCM terminal 1Z
• Open circuit in wiring harness between TR switch terminal I and TCM terminal 1AA
• Open circuit in wiring harness between TR switch terminal F and TCM terminal 2C
• Open circuit in wiring harness between TR switch terminal C and IG key (ACC)
• Short to ground in wiring harness between TR switch terminal C and IG key (ACC)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME PID DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Bulletins and/or on-line repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal? | Yes | Go to the next step.
No | Repair the terminals, then go to Step 12.
4 | INSPECT TR SWITCH CIRCUIT • Inspect the 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

  - TCM terminal 1AA

  • S range: B+
  • Other ranges and all positions: 0V

  - TCM terminal 2C

  • L range: B+
  • Other ranges and all positions: 0V

• Are any of the following terminal voltage turned on for even a moment while shifting the selector lever slowly from the P position to L range?
Yes
Adjust the TR switch, then go to Step 12.
(See TRANSAXLE RANGE (TR) SWITCH ADJUSTMENT [JA5A-EL].)
No | Go to the next step.
5 | INSPECT TR SWITCH CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal? | Yes | Go to the next step.
No | Repair the terminals, then go to Step 12.
6 | INSPECT TR SWITCH CIRCUIT • Disconnect the TR switch connector. • Turn the ignition switch to the ON position (engine off). • Connect the wiring harness-side connector power line and signal line using a jumper wire

  - P position: C and A
  - R position: C and E
  - N position: C and D
  - D range: C and G
  - S range: C and I
  - L range: C and F

• Inspect if the terminal voltage changes.

  - 0 V to B+

• Does the terminal voltage change?
Yes
Go to the next step.
No | Go to Step 9.
7 | INSPECT TR SWITCH FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Inspect for 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
  - S range: C and I
  - L range: C and F

• Is there continuity between TR switch terminals (part side)?
(See TRANSAXLE RANGE (TR) SWITCH INSPECTION [JA5A-EL].)
Yes
Go to Step 12.
No | Replace the TR switch, then go to Step 12. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5A-EL].)
8 | INSPECT TR SWITCH POWER CIRCUIT FOR OPEN CIRCUIT • Inspect the voltage at TR switch terminal C (wiring harness-side). • Is there B+ at TR switch terminal C (wiring harness-side)? | Yes | Go to the next step.
No | Inspect the main fuse. • If normal, repair or replace the wiring harness, then go to Step 12.
9 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the terminals normal? | Yes | Go to the next step.
No | Repair the terminals, then go to Step 12.
10 | INSPECT TR SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between TR switch terminals (wiring harness-side) and TCM terminals (wiring harness-side).

  - P position: A and 2B
  - R position: E and 1W
  - N position: D and 1T
  - D range: G and 1Z
  - S range: I and 1AA
  - L range: F and 2C

• Is there continuity?
Yes
Go to the next step.
No | Repair or replace the wiring harness, then go to Step 12.
11 | INSPECT TR SWITCH CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between TCM terminals (wiring harness-side) and body ground.

  - P position: 2B and body ground
  - R position: 1W and body ground
  - N position: 1T and body ground
  - D range: 1Z and body ground
  - S range: 1AA and body ground
  - L range: 2C and body ground

• Is there continuity?
Yes
Go to the next step.
No | Repair or replace the wiring harness, then go to the next step.
12 | VERIFY TROUBLESHOOTING OF DTC P0706 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the WDS or equivalent. • Drive the vehicle in each range (P, R, N, D, S, and L) for 100 s or more. • Is there pending code? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [JA5A-EL].)
No | Go to the next step.
13 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [JA5A-EL].)
No | DTC troubleshooting completed.
