DTC 96

DTC 96:

Low Oil Lamp Circuit:

CIRCUIT DESCRIPTION
Ignition voltage is supplied directly to the low oil lamp on CKT 39. The Powertrain Control Module (PCM) controls the lamp by providing the ground path through CKT 1173.

When the PCM is commanding a component "ON," the voltage of the control circuit should be "low" (near 0 volts). When the PCM is commanding the control circuit to a component "OFF," the voltage potential of the circuit should be "high" (near battery voltage). The primary function of the driver is to supply the ground for the component being controlled.

Each driver has a fault line which is monitored by the PCM. The PCM will monitor the voltage at the driver. If the fault detection circuit senses a voltage other than what is expected, the fault line status will change and the DTC will set.

DTC 96 WILL SET WHEN:
The PCM detects the wrong voltage potential for 26 seconds on CKT 1173.

ACTION TAKEN (PCM WILL DEFAULT TO)
DTC 96 will be stored in the PCM memory but will not turn "ON" the Malfunction Indicator Lamp (MIL).

DTC CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.

1. Disconnecting the PCM connector will determine if CKT 1173 is shorted to ground or the PCM is at fault.

DIAGNOSTIC AIDS
Inspect the harness and all related connectors including the PCM connections. These may cause an intermittent. Check for damaged or pushed out terminals. Refer to Instrument Panel.
