Test E: DTC B2268 Or DTC B2269 - Steering Wheel Control Switch Open Circuit Or Short To Ground
PINPOINT TEST E: DTC B2268 OR DTC B2269 - STEERING WHEEL CONTROL SWITCH OPEN CIRCUIT OR SHORT TO GROUNDNormal Operation
Under normal operation, the steering wheel control switch receives a ground from the PCM through circuit 848 (DG/OG). The HVAC module -electronic automatic temperature control (EATC) senses the resistance (depending on what button is pressed) from the steering wheel control switch through circuit 1069 (OG/LB).
- DTC B2268 Steering Wheel Control Switch Open Circuit - The module senses no voltage drop on the reference voltage circuit, indicating an open circuit.
- DTC B2269 Steering Wheel Control Switch Circuit Short to Ground - The module senses excessive voltage drop on the reference voltage circuit, indicating a short directly to ground.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Steering wheel control switch
- HVAC module - EATC
- PCM
- Clockspring
