View Full Version : SES Light
1999 GAGT, The SES light comes on usually after hitting a bump in the road such as railway tracks. I've read and cleared the code several times. The code is P1671 ( MIL Malfunction Indicator Lamp) this is the only code displayed. Does anybody know where I should start with this code??

Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition ON and observe a digital multimeter connected between the MIL control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the MIL. A change in voltage will indicate the location of the malfunction.
Seeya, thanks for the information , I'll try that and post the results.:thumbs:
