(1) In case of complaint: ESP and SPS, perform entire test. See BRAKE ASSIST (BAS), ELECTRONIC STABILITY PROGRAM (ESP) & SPEED SENSITIVE POWER STEERING (SPS) ELECTRICAL TESTS PROGRAM (SECTION 23) .

(2) Observe Preparation for Test, see TEST PREPARATION .

(3) Rotor with incorrect tooth count, dirt accumulation on or damage to rotor, incorrect rear axle ratio, wrong wheel or tire size. If DTC appears only after repair work, it may be caused by applying the brakes or driving vehicle on a dynamometer, erase DTC.

(4) When replacing any components, perform CONTROL MODULE ADAPTATION under PROGRAMMING.

(5) See TEST STEP 1.0-5.0 and TEST STEP 13.1-18.0

(6) See TEST STEP 35.0-36.2 and Read DTC (ME-SFI) memory, Check version coding of ME control Module, using HHT

(7) See TEST STEP 6.0-9.1 and Turn steering wheel from left to right stops.

(8) See TEST STEP 28.0-34.1 , N47-5, see TEST STEP 28.0-34.1, N47-5 , see TEST STEP 28.0-34.1 , N47-5

(9) See TEST STEP 28.0-34.1 , see TEST STEP 35.0-36.2

(10) See TEST STEP 6.0-9.1 ; See TEST STEP 10.0-13.0 ; See TEST STEP 13.1-18.0
