ON-BOARD DIAGNOSTIC [AW6A-EL, AW6AX-EL]
STEP
3 INSPECT VOLTAGE OF STARTER RELAY NO.2
CIRCUIT
• Turn the ignition switch to the ON position
(engine off).
• Shift the selector lever to P or N position.
• Inspect for voltage TCM connector terminal A5
(wiring harness-side).
• Is the voltage 0 V?
4 INSPECT TCM CONNECTOR FOR POOR
CONNECTION
• Disconnect the TCM connector.
• Inspect for poor connection (such as damaged/
pulled-out pins, corrosion).
• Are terminals normal?
5 INSPECT VOLTAGE OF STARTER RELAY NO.2
CIRCUIT
• Shift the selector lever to D range or R position.
• Inspect for voltage TCM connector terminal A5
(wiring harness-side).
• Is the voltage B+?
6 INSPECT VOLTAGE OF STARTER RELAY NO.2
TERMINAL E
• Inspect for voltage starter relay No.2 terminal E
(wiring harness-side).
• Is the voltage B+?
7 INSPECT STARTER RELAY NO.2 FOR POOR
CONNECTION
• Turn the ignition switch to the LOCK position.
• Disconnect the starter relay No.2 connector.
• Inspect for poor connection (such as damaged/
pulled-out pins, corrosion).
• Are terminals normal?
8 INSPECT STARTER RELAY NO.2
• Inspect the starter relay No.2.
(See 09-21-4 RELAY INSPECTION)
• Is the relay normal?
9 INSPECT STARTER RELAY NO.2 CIRCUIT FOR
OPEN CIRCUIT
• Inspect for continuity between TCM connector
terminal A5 and starter relay No.2 terminal A
(wiring harness-side).
• Is there continuity?
10 INSPECT STARTER RELAY NO.2 CIRCUIT FOR
SHORT TO GROUND
• Inspect for continuity between starter relay
No.2 terminal A (wiring harness-side) and body
ground.
• Is there continuity?
11 INSPECT STARTER RELAY NO.2 CIRCUIT FOR
SHORT TO POWER
• Turn the ignition switch to the ON position
(engine off).
• Inspect the voltage at starter relay No.2
terminal A (wiring harness-side).
• Is the voltage 0 V?
12 VERIFY TROUBLESHOOTING OF DTC P0817
COMPLETED
• Make sure to reconnect all the disconnected
connectors.
• Clear the DTC from the memory using the M-
MDS.
• Drive the vehicle in D range.
• Is same DTC present?
