Test K
PINPOINT TEST K: THE ANTI-LOCK BRAKE SYSTEM/TRACTION CONTROL (ABS/TC) MODULE OR STABILITY ASSIST MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOLTest K1:
Test K1-K2:
Normal Operation
The ABS/TC module or stability assist module communicates with the diagnostic tool through the SCP communications network circuits 914 (TN/OG) and 915 (PK/LB). If one of the bus wires becomes shorted to ground or voltage, or if some but not all termination resistors are lost communications can continue. Check circuits 914 (TN/OG) and 915 (PK/LB) between the ABS/TC module or stability assist module C155 and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in circuit 914 (TN/OG) or 915 (PK/LB), damage to the DLC C251, damage to the ABS/TC module or stability assist module C155, or a problem in the in-line connectors.
Possible Causes
- SCP circuits 914 (TN/OG) or 915 (PK/LB) shorted to ground or open
- DLC C251
- ABS/TC module or stability assist module
- ABS/TC module or stability assist module C155
