S70B Steering Wheel Controls Switch - Right Front Lower Malfunction

Ignition OFF/Vehicle OFF and all vehicle systems OFF, disconnect the harness connector at the S70B Steering Wheel Controls Switch - Right Front Lower.
Test for less than 10 Ω between the ground circuit terminal 2 and ground.
- If greater than 10 Ω
1. Ignition OFF/Vehicle OFF.
2. Test for less than 2 Ω in the ground circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, repair the open/high resistance in the ground connection.
- If less than 10 Ω
Test for 4.8-5.2 V between the between the following signal circuits and ground
- Favorite Up - Terminal 3
- Favorite Down - Terminal 4
- If less than 4.8 V
1. Ignition OFF/Vehicle OFF, disconnect the harness connector at the S70D Steering Wheel Controls Switch-Right Upper.
2. Test for infinite resistance between the signal circuit and ground.
  - If less than infinite resistance, repair the short to ground on the circuit.
  - If infinite resistance
3. Test for less than 2 Ω in the signal circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the S70D Steering Wheel Controls Switch-Right Upper.
- If more than 5.2 V
1. Ignition OFF/Vehicle OFF, disconnect the harness connector at the S70D Steering Wheel Controls Switch-Right Upper, ignition ON.
2. Test for less than 1 V between the signal circuit and ground.
  - If 1 V or greater, repair the short to voltage on the circuit.
  - If less than 1 V, replace the S70D Steering Wheel Controls Switch-Right Upper.
- If between 4.8-5.2 V
Replace the S70B Steering Wheel Controls Switch - Right Front Lower.
