DTC 44, Steering Wheel Sensor Circuit (Circuit Open Or Shorted To Ground): Testing
- Turn ignition switch to OFF position. Disconnect steering wheel speed sensor. Using DVOM, measure resistance between steering wheel speed sensor connector terminals "A" and "B", "B" and "C", and "A" and "C". Resistance between "A" and "B", and "B" and "C" should be 500-16k ohms. Resistance between "A" and "C" should be 8k-15k ohms. If all resistance measurements are not as specified, replace sensor. If all resistance measurements are as specified, go to next step.
- Disconnect CCM connector C2. Using DVOM, measure resistance between ground and steering wheel speed sensor connector terminal "B", then terminal "A". If resistance is 0-5 ohms at one or both terminals, repair short to ground in 5V ref hi circuit and/or steering wheel sense circuit. If resistance is not 0-5 ohms at one or both terminals, go to next step.
- Install a fused jumper wire between CCM connector C2 terminal C4 and ground. Using DVOM, check for continuity between steering wheel speed sensor connector terminal "A" and ground. If continuity is not present, repair open in 5V ref hi circuit. If continuity is present, go to next step.
- Install a fused jumper wire between CCM connector C2 terminal D14 and ground. Using DVOM, check for continuity between steering wheel speed sensor connector terminal "B" and ground. If continuity is not present, repair open in steering wheel sense circuit. If continuity is present, go to next step.
- Turn ignition switch to OFF position. Check for poor connections at CCM connector. If connections are okay, reconnect CCM connector and all other components. Clear DTCs and check if DTC resets. If DTC resets, replace CCM. If DTC does not reset, problem may be intermittent. Try to recreate fault while performing test by wiggling wiring and connectors. Check for poor connections at all connectors that may be causing intermittent condition.
