Pinpoint Test 2: DTC C1186-ABS Power Relay Output Open Circuit and B1317 and B1318-Battery Voltage High/Battery Voltage Low
PINPOINT TEST 2: DTC C1186-ABS POWER RELAY OUTPUT OPEN CIRCUIT AND B1317 AND B1318-BATTERY VOLTAGE HIGH/ BATTERY VOLTAGE LOWNormal Operation
Fused battery voltage is sent from battery junction box (BJB) fuses 33 (30A) and 17 (40A) to the anti-lock brake system (ABS) module along circuits (W/R) and (R) respectively Fused ignition voltage is sent from smart junction box (SJB) fuse 20 (10A) to the ABS module along circuit (Y/V) and 2 grounds are provided for the module along circuit (B). Operating voltage for the ABS module is normally between 10 and 17 volts.
Possible Causes
^ BJB fuse 33 (30A)
^ BJB fuse 17 (40A)
^ SJB fuse 20 (10A)
^ Circuit open
^ Vehicle battery
^ Charging system
^ ABS module
Caution:
^ Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
Note:
^ DTC B1317 and B1318 are generated when the anti-lock brake system (ABS) module detects system voltage is less than 9 volts or greater than 19 volts for more than 1 second.
