Steering Pad Switch Circuit: Procedure
- INSPECT MULTI-MEDIA MODULE RECEIVER ASSEMBLY
- Disconnect the G36 multi-media module receiver assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G36-30 (SW1) - G36-32 (SWG) No switch pushed 95 to 105 kΩ Seek+ switch pushed Below 2.5 Ω Seek- switch pushed 313 to 345 Ω Volume+ switch pushed 950 to 1050 Ω Volume- switch pushed 2955 to 3265 Ω G36-31 (SW2) - G36-32 (SWG) No switch pushed 95 to 105 kΩ MODE switch pushed Below 2.5 Ω Voice switch pushed 2955 to 3265 Ω On hook switch pushed 313 to 345 Ω Off hook switch pushed 950 to 1050 Ω

- INSPECT STEERING PAD SWITCH ASSEMBLY
- Disconnect the z13 steering pad switch assembly connector.
- Measure the resistance according to the values in the table below.
Standard Resistance

- INSPECT SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY
- Disconnect the z13 steering pad switch assembly connector.
- Disconnect the F98 spiral cable with sensor sub-assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition z13-9 (EAU) - F98-4 (EAU) Center Below 1 Ω 2.5 rotations to the left 2.5 rotations to the right z13-11 (AU1) - F98-6 (AU1) Center Below 1 Ω 2.5 rotations to the left 2.5 rotations to the right z13-10 (AU2) - F98-5 (AU2) Center Below 1 Ω 2.5 rotations to the left 2.5 rotations to the right - After setting the spiral cable with sensor sub-assembly to the center position, rotate the spiral cable with sensor sub-assembly 2.5 times clockwise. Then while rotating the spiral cable with sensor sub-assembly 5 times counterclockwise, measure the resistance as shown in the table below.
Standard Resistance
Tester Connection Condition Specified Condition z13-9 (EAU) - F98-4 (EAU) Always Below 1 Ω z13-11 (AU1) - F98-6 (AU1) Always Below 1 Ω z13-10 (AU2) - F98-5 (AU2) Always Below 1 Ω NOTE:- The spiral cable with sensor sub-assembly is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable with sensor sub-assembly may prevent the airbag from deploying. Refer to the information shown in the brackets.
- As the spiral cable with sensor sub-assembly may break, do not rotate the spiral cable with sensor sub-assembly more than the specified amount.
