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
