Lexus NX: Inspection
INSPECTION
PROCEDURE
1. INSPECT SHIFT PADDLE SWITCH (TRANSMISSION SHIFT SWITCH ASSEMBLY)
(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Shift Paddle Switch RH (Transmission Shift Switch Assembly): Tester Connection | Switch Condition | Specified Condition | SDN - ECC | "-" shift paddle operated and held (down-shift) | Below 2.5 Ω | "-" shift paddle not operated (down-shift) | 1 MΩ or higher | If the resistance values are not as specified, replace the shift paddle switch LH (transmission shift switch assembly). | | *a | Component without harness connected (Shift Paddle Switch LH (Transmission Shift Switch Assembly)) | | |
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance: Shift Paddle Switch RH (Transmission Shift Switch Assembly): Tester Connection | Switch Condition | Specified Condition | SUP - ECC | "+" shift paddle operated and held (up-shift) | Below 2.5 Ω | "+" shift paddle not operated (up-shift) | 1 MΩ or higher | If the resistance values are not as specified, replace the shift paddle switch RH (transmission shift switch assembly). | | *a | Component without harness connected (Shift Paddle Switch RH (Transmission Shift Switch Assembly)) | | |
2. INSPECT NO. 1 SWITCH WIRE
(a) Disconnect the No. 1 switch wire connector from the steering pad switch assembly.
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Switch Condition | Specified Condition | z7-2 (SDN) - z7-3 (ECC) | "-" shift paddle operated and held (down-shift) | Below 2.5 Ω | "-" shift paddle not operated (down-shift) | 1 MΩ or higher | z7-1 (SUP) - z7-3 (ECC) | "+" shift paddle operated and held (up-shift) | Below 2.5 Ω | "+" shift paddle not operated (up-shift) | 1 MΩ or higher | If the resistance value is not as specified, replace the No. 1 switch wire. | | *a | No. 1 switch wire (to Steering Pad Switch Assembly) | | |
