PINPOINT TEST K: DTC C1288-BRAKE PRESSURE TRANSDUCER INPUT CIRCUIT FAILURE

Test K1:

Tests K1 (continued) - K3:

Tests K3 (continued) - K5:

Test K5 (continued):

Normal Operation
The brake pressure transducer sends current to the ABS module proportional to the driver's brake pedal application.

Reference voltage is supplied by circuit 7-CF64 (YE/BK). Ground is provided through circuit 9-CF64 (BN/YE). The transducer current is supplied by circuit 8-CF64 (WH/BK).

Possible Causes
^ reference voltage circuit 7-CF64 (YE/BK)
^ ground circuit 9-CF64 (BN/YE)
^ transducer signal circuit 8-CF64 (WH/BK)
^ brake pressure transducer
^ 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.
