DIAGNOSTIC RESPONSE:None CIRCUIT DESCRIPTION:The difference in pressure between main (before the filter) and Torque Converter Clutch (TCC) lockup determines whether to stroke or destroke the Filter Life Indicator (FLI) pressure valve in the prognostics valve body within the control valve module. When this pressure differential exceeds 175-200 kPa (25-30 psi), the FLI pressure valve moves against the return spring and allows control main pressure to open the Pressure Switch 2 (PS2). When the pressure differential is less, the hydraulic circuit to PS2 switch exhausts and closes the PS2 switch. An active DTC P0847 indicates that the PS2 circuit is detected...

DIAGNOSTIC RESPONSE:No CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) requires direct battery voltage input to operate. This test detects abnormal power down of battery voltage to the TCM on terminals 10 and 70 with ignition sense ON. NOTE: The TCM battery power signal must be provided through a 10A or 15A fuse, or a manually-reset circuit breaker. CONDITIONS FOR RUNNING THE DTC:1. Engine speed above 350 rpm for at least 0.5 seconds,2. DTC test runs at after each normal TCM initialization or after TCM reset. CONDITIONS FOR SETTING THE DTC:DTC P0880 sets during the next ignition cycle if battery power is...

DIAGNOSTIC RESPONSE:None CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) requires direct battery voltage input to operate. This test monitors for low or excessive swings in battery voltage to the TCM on terminals 10 and 70. NOTE: The TCM battery power signal must be provided through a 10A or 15A fuse, or a manually-reset circuit breaker. CONDITIONS FOR RUNNING THE DTC:1. Engine speed above 500 rpm or more for at least 1.5 seconds.2. DTC test runs at 0.50 second intervals. CONDITIONS FOR SETTING THE DTC:DTC P0881 sets when the TCM detects battery voltage is less than 9 volts after engine runtime over...

DIAGNOSTIC RESPONSE:DNS, SOLD OFF (hydraulic default) CIRCUIT DESCRIPTION:The Transmission Control Module (TCM) requires direct battery voltage input to operate. This test monitors for low battery voltage to the TCM on terminal 10 and 70. NOTE: The TCM battery power signal must be provided through a 10A or 15A fuse, or a manually-reset circuit breaker. CONDITIONS FOR RUNNING THE DTC:1. Engine speed above 400 rpm for at least 30 seconds.2. DTC test runs at 0.025 second intervals. CONDITIONS FOR SETTING THE DTC:DTC P0882 sets:When battery voltage is less than 9 volts after engine runtime over 30 seconds. ACTION TAKEN WHEN THE...
