Scheme 18

1. Remove the column cover.
2. Turn the ignition switch to the ON position and measure the voltage between steering angle sensor terminal A and ground. If there is any malfunction, inspect the wiring harness between steering angle sensor terminal A and ignition switch.

Repair or replace if necessary, (with DSC) Standard voltage B+
3. Measure the voltage between steering angle sensor terminal D and ground. If there is any malfunction, inspect the wiring harness between steering angle sensor terminal D and EHPAS control module terminal 3A. Repair or replace if necessary, (without DSC) If there is any malfunction, inspect the wiring harness between steering angle sensor terminal D and DSC HU/CM terminal AH. Repair or replace if necessary, (with DSC) Standard voltage 0V
4. Turn the ignition switch off.
5. Connect the M-MDS to the DLC-2.
6. Select the STEER_RATE PID. (see «ELECTRO HYDRAULIC POWER ASSIST STEERING (EHPAS) ON-BOARD DIAGNOSIS [ELECTRO HYDRAULIC POWER ASSIST STEERING (EHPAS)]»(ref-345272-S25672473922009102000000) .)
7. Verify the STEER_RATE changes when the steering wheel is turned to the left and right. If there is any malfunction, replace the steering angle sensor. (See «CLOCK SPRING REMOVAL/INSTALLATION»(ref-345267-S26162634342009102000000) .) Standard When the steering wheel is turned to the left: STEER_RATE changes positively. When the steering wheel is turned to the right: STEER_RATE changes negatively.
