DTC P0705 [JA5A-EL]

BME050218901205

DTC P0705 | Transaxle range (TR) switch circuit malfunction (short circuit)
--- | ---
DETECTION CONDITION | • If two or more range signals are input from TR switch for 5 s or more, the TCM determines that there is a malfunction. Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the TCM detects the above malfunction conditions in two consecutive drive cycles.
• PENDING CODE is available above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• The HOLD indicator light flashes.
• The DTC is stored in the TCM memory.
POSSIBLE CAUSE | • TCM malfunction. • Short to power supply in wiring harness between TR switch terminal A and TCM terminal 2B • Short to power supply in wiring harness between TR switch terminal E and TCM terminal 1W • Short to power supply in wiring harness between TR switch terminal D and TCM terminal 1T
• Short to power supply in wiring harness between TR switch terminal G and TCM terminal 1Z
• Short to power supply in wiring harness between TR switch terminal I and TCM terminal 1AA
• Short to power supply in wiring harness between TR switch terminal F and TCM terminal 2C
• Damaged connector between TR switch and TCM
• TR switch malfunction

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 | VERIFY CURRENT INPUT SIGNAL STATUS-IS CONCERN INTERMITTENT OR CONSTANT? • Connect volt meter to TCM. • Turn the ignition switch to the ON position (engine off). • Inspect the TCM terminal voltage. (See TCM INSPECTION [JA5A-EL] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
(See TCM INSPECTION [JA5A-EL] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)

  - TCM terminal 2B

  • P position: B+
  • Other positions and all ranges: 0 V

  - TCM terminal 1W

  • R position: B+
  • Other positions and all ranges: 0 V

  - TCM terminal 1T

  - N position: B+
  - Other positions and all ranges: 0 V

  - TCM terminal 1Z

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

  - TCM terminal 1AA

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

  - TCM terminal 2C

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

• Are two or more of following terminal voltage at the same time when shifting selector lever from the P position to L range?
Yes
Go to the next step.
No | Go to the intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING [AJ].)
4 | INSPECT TR SWITCH CONNECTOR • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect the pins for bent terminals using a mirror. • Are the TR switch terminals normal? | Yes | Go to the next step.
No | Repair the terminals or replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5A-EL].)
5 | INSPECT TR SWITCH CIRCUIT MALFUNCTION • Turn the ignition switch to the ON position (engine off). • Does the TCM terminal voltage change from B+ to 0 V when the TR switch connector is disconnected? | Yes | Go to the next step.
No | Go to Step 7.
6 | INSPECT TR SWITCH CONTINUITY • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Inspect the TR switch for continuity in positions/ranges failed in Step 4. • Is there continuity between the TR switch terminals (part side)?
(See TRANSAXLE RANGE (TR) SWITCH INSPECTION [JA5A-EL].)
Yes
Go to Step 8.
No | Replace the TR switch, then go to Step 8. (See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [JA5A-EL].)
7 | INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Measure the voltage at TR switch terminal A, E, D, G, I, and F (wiring harness-side). • Is there 0 V at the TR switch wiring harness-side connector? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to the next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the WDS or equivalent. • Turn the ignition switch to the ON position (engine off). • Drive the vehicle in each range (P, R, N, D, S, and L) for 5 s or more.
• Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [JA5A-EL].)
No | Go to the next step.
9 | 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.
