Pinpoint Test B: Select Shift Does Not Operate Correctly

  1. B1 TEST THE PADDLE SHIFTER CIRCUITS FOR AN OPEN 
    NOTE: Both RH and LH paddle shifter connectors are the same and share the same circuits.
    • Remove the paddle shifter. Refer to SELECTOR LEVER - PADDLE SHIFT .
    • For vehicles equipped with a 3.7L engine, disconnect PCM C175B.
    • For vehicles equipped with a 3.7L engine, disconnect PCM C175T.
    • For vehicles equipped with a 3.5L Gasoline Turbocharged Direct Injection (GTDI) engine, disconnect PCM C1381B.
    • For vehicles equipped with a 3.7L engine, measure the resistance between the paddle shifter connector, harness side and PCM C175B and C175T, harness side using the following chart:
      Paddle Shifter Connector Pin Number Circuit Function/Number (Color) PCM Connector Pin Number
      1 Upshift signal/CET43 (GY) C175T-42
      2 Ground supply/RE407 (YE/VT) C175B-58
      3 Downshift signal/CET42 (GN/VT) C175T-44

    • For vehicles equipped with a 3.5L GTDI engine, measure the resistance between the paddle shifter connector, harness side and PCM C1381B, harness side using the following chart:
      Paddle Shifter Connector Pin Number Circuit Function/Number (Color) PCM Connector Pin Number
      1 Upshift signal/CET43 (GY) C1381B-23
      2 Ground supply/RE407 (YE/VT) C1381B-56
      3 Downshift signal/CET42 (GN/VT) C1381B-24

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to  B4.
    • No  : GO to B2.
  2. B2 TEST THE STEERING WHEEL WIRING HARNESS PADDLE SHIFTER CIRCUITS FOR AN OPEN 
    • Remove the driver air bag module. Refer to SUPPLEMENTAL RESTRAINT SYSTEM .
    • Disconnect: Steering Wheel Internal Wiring Harness C218B.
    • Measure the resistance between the paddle shifter connector, harness side and steering wheel internal wiring harness C218B, harness side using the following chart:
      Paddle Shifter Connector Pin Number Circuit Function (Color) Steering Wheel C218B Pin Number
      1 Upshift signal (VT/OG) 6
      2 Ground supplied from PCM (GY) 2
      3 Downshift signal (YE/RD) 12

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to B3.
    • No  : INSTALL a new steering wheel. REFER to STEERING COLUMN .
  3. B3 TEST THE CLOCKSPRING INTERNAL PADDLE SHIFTER CIRCUITS FOR AN OPEN 
    • Remove the steering column shroud. Refer to STEERING COLUMN .
    • Disconnect: Clockspring C218A.
    • Measure the resistance of the paddle shifter circuits through the clockspring, using the following chart:
      Clockspring Pin Number C218B End Component Side Circuit Function Clockspring Pin Number C218A End Component Side
      6 Upshift signal 3
      2 Ground supplied from PCM 7
      12 Downshift signal 11

    • Is the resistance less than 5 ohms? 
    • Yes  : REPAIR the circuit in question between clockspring C218A and the PCM connector for an open.
    • No  : INSTALL a new clockspring. REFER to SUPPLEMENTAL RESTRAINT SYSTEM .
  4. B4 TEST THE PADDLE SHIFTER SIGNAL CIRCUITS FOR A SHORT TO GROUND 
    • Measure the resistance between the paddle shifter connector, harness side and ground using the following chart:
      Paddle Shifter Connector Function/Circuit
      Pin 1 Upshift signal/CET43 (GY)
      Pin 3 Downshift signal/CET42 (GN/VT)
      Fig 5: Measuring Resistance Between Paddle Shifter Connector, Harness Side And Ground

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : GO to  B6.
    • No  : GO to B5.
  5. B5 TEST THE STEERING WHEEL WIRING HARNESS PADDLE SHIFTER SIGNAL CIRCUITS FOR A SHORT TO GROUND 
    • Remove the driver air bag module. Refer to SUPPLEMENTAL RESTRAINT SYSTEM .
    • Disconnect: Steering Wheel Internal Wiring Harness C218B.
    • Measure the resistance between the paddle shifter connector, harness side and ground using the following chart:
      Paddle Shifter Connector Function/Circuit
      Pin 1 Upshift signal/CET43 (GY)
      Pin 3 Downshift signal/CET42 (GN/VT)

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : REPAIR the circuit in question between clockspring C218A and the PCM connector for a short.
    • No  : INSTALL a new steering wheel. REFER to STEERING COLUMN .
  6. B6 CHECK THE PADDLE SHIFTER 
    • Measure the resistance between pins 2 and 1, component side while cycling the paddle shifter to the upshift position.
