Operation CHARM: Car repair manuals for everyone.

Four Wheel Anti-Lock Brake System (4WABS)

NOTE: Do not raise vehicle on hoist and accelerate to 40 km/h (25 mph) to simulate driving the vehicle. Erroneous sensor codes will be set.

NOTE: The NGS is used to clear DTCs by performing the ABS code clear procedure. No other manual method can be used to clear DTCs.

All diagnostic trouble codes must be output, all concerns corrected (Antilock light off) and vehicle driven about 40 km/h (25 mph) before diagnostic trouble codes will be erased.
