P0888-TRANSMISSION RELAY ALWAYS OFF (CONTINUED)
6.
(T15) TRANSMISSION CONTROL RELAY CONTROL CIRCUIT OPEN
Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector.
NOTE: Check connectors - Clean/repair as necessary.
CAUTION: Do not probe the PCM harness connectors. Probing
the PCM harness connectors will damage the PCM terminals
resulting in poor terminal to pin connection. Install Miller Special
Tool #8815 to perform diagnosis.
Measure the resistance of the (T15) Transmission Control Relay Con-
trol circuit between the Transmission Control Relay connector and the
appropriate terminal of special tool #8815.
Is the resistance above 5.0 ohms?
Yes
>> Repair the (T15) Transmission Control Relay Control cir-
cuit for an open.
Perform 42RLE TRANSMISSION VERIFICATION TEST -
VER 1.
No
>> Go To 7
7.
(T15) TRANSMISSION CONTROL RELAY CONTROL CIRCUIT SHORT TO GROUND
Measure the resistance between ground and the (T15) Transmission
Control Relay Control circuit.
Is the resistance below 5.0 ohms?
Yes
>> Repair the (T15) Transmission Control Relay Control cir-
cuit for a short to ground.
Perform 42RLE TRANSMISSION VERIFICATION TEST -
VER 1.

CAUTION: Do not probe the PCM harness connectors. Probing
the PCM harness connectors will damage the PCM terminals
resulting in poor terminal to pin connection. Install Miller Special
Tool #8815 to perform diagnosis.
Measure the resistance between ground and the (T16) Transmission
Control Relay Output circuit.
Is the resistance below 5.0 ohms?
Yes
>> Go To 10
No
>> Repair the Fused B+ circuit for an open.

INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set the DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wiring and connectors while checking for shorted and open circuits.
With the scan tool, check the EATX EVENT DATA to help identify the conditions in which the DTC was set.
Were there any problems found?
Yes
>> Repair as necessary.
