6. Circuit integrity C1835/31 (G) - C1452/5 (G).
7. Gearbox Gear Selector Switch.
8. Electronic Automatic Transmission ECU.

1. Connectors C1835, C1452.
CONNECTOR
Check for connector not correctly latched, backed out pins, damaged pins, corroded pins

2. Circuit integrity C1835/34 (B) - C1452/1 (B).
CIRCUIT_INTEGRITY
Check for open circuit, short circuit to ground, supply or other circuit, damaged or unlatched connector, intermediate connectors or headers

3. Circuit integrity C1835/24 (O) - C1452/2 (O).
CIRCUIT_INTEGRITY
Check for open circuit, short circuit to ground, supply or other circuit, damaged or unlatched connector, intermediate connectors or headers

4. Circuit integrity C1835/14 (P) - C1452/3 (P).
CIRCUIT_INTEGRITY
Check for open circuit, short circuit to ground, supply or other circuit, damaged or unlatched connector, intermediate connectors or headers

5. Circuit integrity C1835/4 (Y) - C1452/4 (Y).
CIRCUIT_INTEGRITY
Check for open circuit, short circuit to ground, supply or other circuit, damaged or unlatched connector, intermediate connectors or headers

6. Circuit integrity C1835/31 (G) - C1452/5 (G).
CIRCUIT_INTEGRITY
Check for open circuit, short circuit to ground, supply or other circuit, damaged or unlatched connector, intermediate connectors or headers

7. Gearbox Gear Selector Switch.
CHECK THE FOLLOWING:
Check the state of each gear switch input against each gear position against the following table. Each entry in the table states, for each gear position, the expected connectivity between the common line, C1452/5, and each gear switch line.
P R N D
L1 C1452/1 SC OC SC OC
L2 C1452/2 SC OC SC OC
L3 C1452/3 SC SC OC OC
L4 C1452/4 OC SC SC SC

PASS VALUES:
Short circuit (SC) less than 2.0 Ohms.
Open circuit (OC) greater than 2.0 Ohms.
