PINPOINT TEST A : P0740
TEST CONDITIONSDETAILS/RESULTS/ACTIONS
A1: RETRIEVE DTCS
• NOTE: Battery and or ECM disconnection prior to scanning wi
ll erase all data, ensure that the correct DTC is present.
Connect the scan tool 1
Have the DTC(s) and freeze frame data been recorded?
Yes GO to A2
A2: CHECK TORQUE CONVERTER CLUTCH SOLENOID RESISTANCE
With, EM062 disconnected, measure the resistance between 1

EM062/017 and EM062/038.
Is the resistance >4.0 and <8.0 OHM?
Yes GO to A6
No GO to A3
A3: CHECK HARNESS SIGNAL CONTINUITY
With EM062 and GB001 disconnected, measure the resistance between GB001/011 and EM062/017. 1
Is the resistance < 0.5 OHM?
Yes GO to A4
No
Inspect EM062, EM044 and GB001 for corrosion, bent /
pushed back pins or locate harness. Repair as necessary and
test the system for normal operation.
A4: CHECK HARNESS +VE CONTINUITY

With EM062 and GB001 disconnected, measure the resistance between GB001/006 and EM062/038 1
Is the resistance < 0.5 OHM?
Yes GO to A5
No Inspect EM062, EM044 and GB001 for corrosion, bent /
pushed back pins or locate harness. Repair as necessary and
test the system for normal operation.
A5: CHECK FOR SHORT TO B+

Pinpoint test B: P0740, P1744
With EM062 and EM061 disconnected, measure the voltage
between EM062/038 and EM061/030. 1
0V?
Yes GO to A6
No Inspect EM062, EM063, EM044 and EM061 for corrosion,
bent / pushed back pins or locate harness. Repair as
necessary and test the syst em for normal operation.
A6: END
Perform appropriate service drive cycle and check for the
presence of DTC. 1
Has the fault code cleared?
Yes
STOP
No Contact Jaguar Service
PINPOINT TEST B : P0740, P1744
TEST CONDITIONSDETAILS/RESULTS/ACTIONS
B1: RETRIEVE DTCS
• NOTE: Battery and or ECM disconnection prior to scanning wi ll erase all data, ensure that the correct DTC is present.

Pinpoint test C: P0702, P0753, P0758, P0763
Connect the scan tool 1
Have the DTC(s) and freeze frame data been recorded?
Yes GO to B2
B2: RENEW TORQUE CONVERTER
Renew the torque converter 1
Has the torque converter been renewed?
Yes GO to B3
B3: END
Drive the vehicle for a period from cold to include idle, brisk
acceleration and steady state cruising up to and including
normal engine temperature. Check for the presence of DTC 1
Has the fault code cleared?
Yes STOP
No Contact Jaguar Service
PINPOINT TEST C : P0702, P0753, P0758, P0763
TEST CONDITIONSDETAILS/RESULTS/ACTIONS
C1: RETRIEVE DTCS

Connect the scan tool 1
Have the DTC(s) and freeze frame data been recorded?
Yes GO to C2
C2: CHECK HARNESS +VE CONTINUITY

With EM062 and GB001 disconnected, measure the
resistance between GB001/006 and EM062/038 1
Is the resistance < 0.5 OHM?
Yes GO to C3
No Inspect EM062, EM044 and GB001 for corrosion, bent /
pushed back pins or locate harness. Repair as necessary
and test the system for normal operation.
C3: CHECK FOR SHORT TO B+

With EM062 and GB001 disconnected, measure the
resistance between EM062/038 and EM061/029 1
> 10 MOHM?
Yes GO to C4
No Inspect EM062, EM044 and GB001 for corrosion, bent /
pushed back pins or locate harness. Repair as necessary
and test the system for normal operation.
C4: CHECK HARNESS SHORT TO GROUND

With EM062 and GB001 disconnected, measure the
resistance between EM062/038 and EM008R 1
Is the resistance > 10 MOHM?
Yes GO to C5
No Inspect EM062 for corrosion, bent / pushed back pins or
locate harness. Repair as necessary and test the system
for normal operation.
C5: CHECK HARNESS CONTINUITY - SOLENOID
