- INSPECT SHIFT PADDLE SWITCH (TRANSMISSION SHIFT SWITCH ASSEMBLY)
- Shift Paddle Switch LH (Transmission Shift Switch Assembly):
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
(Shift Paddle Switch LH (Transmission Shift Switch Assembly))Standard Resistance
Tester Connection Condition Specified Condition Result 1 (SDN) - 2 (ECC) "-" (Down shift) shift paddle switch operated and held Below 2.5 Ω Ω 1 (SDN) - 2 (ECC) "-" (Down shift) shift paddle switch not operated 1 MΩ or higher MΩ 1 (SDN) - 3 (ECC1) "-" (Down shift) shift paddle switch operated and held Below 2.5 Ω Ω 1 (SDN) - 3 (ECC1) "-" (Down shift) shift paddle switch not operated 1 MΩ or higher MΩ HINT:
If the result is not as specified, replace the shift paddle switch LH (transmission shift switch assembly).
- Measure the resistance according to the value(s) in the table below.
- Shift Paddle Switch RH (Transmission Shift Switch Assembly):
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
(Shift Paddle Switch RH (Transmission Shift Switch Assembly))Standard Resistance
Tester Connection Condition Specified Condition Result 1 (SUP) - 2 (ECC) "+" (Up shift) shift paddle switch operated and held Below 2.5 Ω Ω 1 (SUP) - 2 (ECC) "+" (Up shift) shift paddle switch not operated 1 MΩ or higher MΩ HINT:
If the result is not as specified, replace the shift paddle switch RH (transmission shift switch assembly).
- Measure the resistance according to the value(s) in the table below.
- Shift Paddle Switch LH (Transmission Shift Switch Assembly):
