PINPOINT TEST L: DTC C1730-REFERENCE VOLTAGE OUT OF RANGE (+5 V)Tests L1 - L2:
Tests L2 (continued) - L4:
Tests L5 - L7:
Normal Operation
The 5-volt reference voltage is supplied by the Anti-Lock Brake Module (ABS).
Reference voltage is supplied by circuit 7-CF64 (YE/BK). The reference voltage circuit returns to the ABS module through the PTS switch circuit 9-CF65 (BN/WH) and the brake pressure transducer circuit 9-CF64 (BN/YE).
Possible Causes
^ circuit 7-CF64 (YE/BK)
^ ground circuit 9-CF65 (BN/WH)
^ ground circuit 9-CF64 (BN/YE)
^ ABS module
^ IVD input/output components: -PTS switch -brake pressure transducer
CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
