DTC 211 & DTC 212: Front Wheel Sensor Signal - Wheel Speeding Correct

WARNING: This page is about a different car, the 1996 Volvo 850. However, it is still accessible from the selected car via links, so may be relevant.

If fault is intermittent, go to step 9). If fault is permanent, check if additional DTCs are present. If only DTCs 211 and 212 are present, go to step 3). If DTCs 211, 212, 311, and/or 312 are present (for same wheel), perform diagnosis starting with step 7) in DTC 311 & 312 test, then go to next step.
Turn ignition on. Use scan tool and enter rolling values, list No. 1. Test drive vehicle. Maintain an even speed without turning. If the wheel in question has the same speed as other wheels, go to step 9). If suspect wheel does not have the same speed as other wheels, go to next step. 6 3) Turn ignition off. Disconnect ABS control module. Connect breakout box. Connect ohmmeter between breakout box pins No. 4 and 11 (DTC 211), or between pins No. 3 and 18 (DTC 212). If ohmmeter reads 1040-1160 ohms, go to step 5). If ohmmeter does not read 1040-1160 ohms, go to next step.
Remove wheel in question. Clean wheel sensor contact brush and blow clean with air. Disconnect wheel sensor 2-pin connector. Connect ohmmeter between wheel sensor connector terminals No. 1 and 2. If ohmmeter reads 1040-1160 ohms, DTC was caused by poor terminal contact. Repair as necessary. If ohmmeter does not read 1040-1160 ohms, replace wheel sensor.
Ensure ignition is off. Reconnect ABS control module. Turn ignition on. Connect voltmeter between breakout box terminals No. 4 and 8 (DTC 211), or between breakout box terminals No. 3 and 8 (DTC 212). If voltmeter reads 2.3 volts, go to step 8). If voltmeter reads greater than 2.3 volts, go to step 7). If voltmeter reads less than 2.3 volts, go to next step.

Check for a short to ground in wiring between wheel sensor connector terminals and ABS control module. See DTC 211 & 212 TERMINAL IDENTIFICATION table. Refer to wiring diagram for control module terminal identification. Repair as necessary.

1		18

Check for a short to voltage in wiring between wheel sensor connector terminals and ABS control module. See DTC 211 & 212 TERMINAL IDENTIFICATION table. Repair as necessary.
Check wheel bearing for suspect wheel. Front wheel bearings are not adjustable. Repair as necessary. If wheel bearing is okay, check for possible seized brakes. Repair as necessary. If brakes are okay, check wheel sensor for dirt, damage, or looseness. Repair or replace as necessary. If wheel sensor is okay, ensure pulse wheel is positioned securely, all teeth are intact, and not scratched. Repair or replace as necessary. If pulse wheel is okay, DTC was caused by poor contact in wheel sensor or ABS control module terminals. Repair as necessary.
If fault is intermittent, check for causes of a locked wheel, such as wheel bearing, brake caliper or parking brake. Check wheel sensor and pulse wheel. Check wiring between ABS control module and wheel sensor for intermittent opens, short to ground, or short to voltage. See DTC 211 & 212 TERMINAL IDENTIFICATION table. Repair as necessary.
